5x - 6y = 4
3y + 2x = 7
How many times will the lines intersect?
Answer:
Once
Step-by-step explanation:
I put it into slope intercept first
(5/6)x - (2/3) = y
(2/3)x - (7/3) = y
Both lines are linear so they are straight. Since the two are not parallel or have the same slope then they will cross once.

The units of the subway map at the right are in miles. Suppose the routes between stations are straight, find the distance you would travel between each the Elm and Symphony Stations. Round your answer to the nearest tenth of a mile.
Answer:
[tex]4\sqrt{5}[/tex] miles.
Step-by-step explanation:
From the given figure it is clear that the coordinates of Elm station are (-3,-6) and coordinates of Symphony station are (1,2).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the distance between Elm and Symphony stations is
[tex]D=\sqrt{(1-(-3))^2+(2-(-6))^2}[/tex]
[tex]D=\sqrt{(1+3)^2+(2+6)^2}[/tex]
[tex]D=\sqrt{(4)^2+(8)^2}[/tex]
[tex]D=\sqrt{16+64}[/tex]
[tex]D=\sqrt{80}[/tex]
[tex]D=4\sqrt{5}[/tex]
Therefore, the distance between Elm and Symphony stations is [tex]4\sqrt{5}[/tex] miles.

Answer: A
Step-by-step explanation:
6x + 12x + 90 = 180
18x + 90 = 180
-90 -90
18x =90
x= 5
6(5) + 12(5) + 90 = 180
30 + 60 + 80 = 180
180= 180 It makes sense that it is A because there is one right angle which has a measure of 90 degrees and the other one have two measures 6x and 12x and both of them have to also equal 90 degrees. So 90 pluse 6x plus 12x has to equal 180 because they all lie on a straight line and a straight line has an angle measure of 180 degrees.

PLEASE HELP ME FOR BRAINLIEST ANSWER An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 280 feet of antique picket fencing are to be used to enclose the garden, find the dimensions of the garden. The length of the garden is ? feet.
Answer:
Length: 84 ft
Width: 56 ft
Step-by-step explanation:
Let's define some variables first.
Call the length l and width w.
We know that w = 2/3l. Therefore, we can express w in terms of l with this expression.
Now, let's set up an equation. The flower garden is rectangular, and 280 feet of fencing are used to enclose the garden. This represents perimeter.
Remember the formula for perimeter of a rectangle: 2l + 2w
Let's substitute 2/3l for w:
2l + 2*2/3l = P
2l + 4/3l = 280
2 4/3l = 280
10/3l = 280
l = 84
Now, we know that the length is equal to 84 feet. We can multiply 84 feet by 2/3 to find the width.
84*2/3 = 56
Length: 84 ft
Width: 56 ft
Let's plug these values into the formula and see if they give us the correct perimeter:
2l + 2w = P
2*84 + 2*56 = P
168 + 112
= 280 feet
These are the correct dimensions!
Hope this helps! You can reach out to me if you have further questions or concerns! :)

You pay $8 to play the following game of chance. There is a bag containing 15 balls, 7 are red, 6 are green and the rest are yellow. You will win $14 if you draw a yellow ball, and $11 if you draw a green ball. What is the expected value of the game?
Answer:
Green ball. $11
Step-by-step explanation:
Let's see.
15 balls. 7 are red. 6 are green. rest are yellow. That means there are 2 yellow balls.
Since there are more greens than yellows, you have a better chance of getting a green. That means you have a higher chance of getting $11
The total expected value of the game is $2 if you pay $8 to play the following game of chance.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
You pay $8 to play the following game of chance. There is a bag containing 15 balls, 7 are red, 6 are green and the rest are yellow.
Yellow balls = 15 - 7 - 6= 2
Probability of yellow = 2/15
Probability of green = 6/15
Expected value of the game = 6(2/15) + 3(6/15) = $2
Thus, the total expected value of the game is $2 if you pay $8 to play the following game of chance.

A scientist is running an experiment with
two species of bacteria that grow exponentially.
If species A doubles in population every
two days, species B doubles in population
every five days, and each species began the
experiment with a population of 50 bacteria,
what will the difference be between the
populations of the two species after ten days?
(A) 200
(B) 800
(C) 1,200
(D) 1,400
Answer:
D 1,400
Step-by-step explanation:
Species A doubles every 2 days and species B doubles every 5 days, so in 10 days, species A will double 10/2 = 5 times and species B will double 10/5=2 times. After 10 days from an initial population of 50 in each species, species A will have 50 x 2 ^5= 50 x 32 = 1,600 population while species B will have 50 x 2 ^2 = 200 population. Their difference is 1,600-200 = 1,400.

Sean is one-fourth his dad's height. If his dad is 6 feet, 6 inches tall, how tall is Sean?
Answer:
19 1/2 inches.
Step-by-step explanation:
edge 2020 OwO
Answer:
19.5 inches a.k.a. 1 foot and 7.5 inches
Step-by-step explanation:
1) To make it easier, convert Sean's dad's height into solely inches.
6 feet and 6 inches = 6(12) + 6 = 72 + 6 = 78 inches
2) Find out what is one-fourth of Sean's dad's height.
In order to do that, you must simply multiply 78 by [tex]\frac{1}{4}[/tex].
[tex]78(\frac{1}{4} ) = 19.5[/tex]
3) Convert back to feet and inches (if necessary)...
19.5 inches = 12 + 7.5 = 1 foot and 7.5 inches

I’m stuck with this question :(
Answer:
The same number was not added to both sides.
Step-by-step explanation:
Given:
t - 8 = 65
in the next step it states something wrong, because it should have been this:
t - 8 = 65
add +8 left and right of the = sign.
t - 8 + 8 = 65 + 8
t + 0 = 73
t = 73
So the error made what's that
The same number was not added to both sides.
Answer:
The same number was not added to both sides
Step-by-step explanation:
t - 8 = 65
Add 8 to each side
t - 8+8 = 65+8
The student added 8 on one side and 65 on the other
t = 73
Graphs of functions on the interval [−4, 4] are depicted below. For each function, find:
1) The domain
2) Zeros of a function (the values of x where the function is zero)
3) Intervals where the function is positive and intervals where it is negative
Answer:
Domain : [-4,4} or [tex]-4\leq x\leq 4[/tex]
Zeros of the function: (-2, 0, 2)
Intervals when function is positive: (0,2)
Intervals where function is negative: (-4,0), (2,4)
Step-by-step explanation:
Domain can be defined as the input of all possible values of x in the given interval. We can se from the graph that minimum value of x is -4 while maximum value of x is 4. So
[tex]-4\leq x\leq 4[/tex]
The value of function becomes 0 at three places, when x becomes -2,0 or 2
We can see that the function is negative throughout the interval (-4,0), then it become positive from (0,2), then it becomes negative again from (2,4)

n+7=3n ⇒ 2n=7 ⇒ n= 3.5
VX= 2*(n+7) = 2*(3.5+7)= 21
in case you need
WY= 2*(4n+1)= 2*(4*3.5+1)= 30
Write the equation of a line that passes through (-5,6) and has a slope of 4, please!
Answer:
y = 4x + 26
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (-5, 6) and Gradient (m): 4
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - 6 = 4(x-(-5))
This becomes:
y - 6 = 4 (x+5)
y - 6 = 4x + 20
Keep solving by moving the 6 over to the other side:
y = 4x + 20 + 6
y = 4x + 26
An easy way to double check:
1) the coefficient of x is the slope. We got 4x, and the slope is 4, so that's correct.
2) Substitute x=-5 into the equation, and we get 6, which is the exact coordinate that they gave us. This is also right.
Hope this helped : )

Joe is commissioned to build a small rectangular garden area on community property. The landscape committee requested that the garden be 10 feet longer than it is wide. Joe has up to 90 feet of material to use for the perimeter. What is the maximum width w of the garden?
Write an expression that represents the length of the garden.
Write the inequality that models the perimeter of the garden.
Solve the inequality.
Answer:
length = width + 10
4*width + 20 ≤ 90
width ≤ 17.5 feet
Step-by-step explanation:
The perimeter of a rectangle is given by:
Perimeter = 2*length + 2*width
The length needs to be 10 feet longer than the width, so we have:
length = width + 10
Using this length in the perimeter equation, we have:
Perimeter = 2*(width + 10) + 2*width = 4*width + 20
The perimeter needs to be up to 90 feet, so we have:
P ≤ 90
4*width + 20 ≤ 90
4*width ≤ 70
width ≤ 17.5 feet
the maximum width of the garden is 17.5 feet
A school has a square playground with each side
measuring 120 feet. A scale drawing of the
playground uses the scale = inch equals 12 feet.
What is the length of a side of the playground on
this scale drawing?
Help!
Answer:
10 inches
Step-by-step explanation:
The length of the playground in its actual size is 120 feet.
The scale drawing uses a scale of 1 inch to 12 feet.
This means that 1 inch in the drawing equals 12 feet in actual size.
Therefore, the length of the playground on the scale drawing is:
1 inch = 12 feet
x = 120 feet
Cross-multiply:
120 * 1 = 12 * x
=> x = 120 / 12 = 10 inches
The length of a side of the playground on the scale drawing is 10 inches.

K. 28
Answer:
5
Step-by-step explanation:
first you do 11 divided by 5
then you multiply it by 2
which gives you 4.4
the closest number is 5
correct me if i am wrong
Answer:
H. 22
Step-by-step explanation:
- The car travels 11 inches every 5 seconds, so in one second it travels:
11 inches / 5 seconds = 2.2 inches/second
- In 2 minutes (120 seconds), the car travels:
2.2 inches/second * 120 seconds = 264 inches
- To convert inches to feet, we can divide by the number of inches in a foot:
264 inches / 12 inches/foot = 22 feet
