The scale of a map says that 3 cm represents 10 km.
What distance on the map (in centimeters) represents an actual distance of 5 kilometers?
Answer:
1.5 cm
Step-by-step explanation:
5 km is half of 10 km.
1.5 cm is half of 3 cm.
y= 10x +2 and -5x + 4y=-27
Answer:
x = -1
y = -8
Step-by-step explanation:
if y=10x+2 then we can substitute that expression in for 'y' in the second equation to solve for 'x':
-5x + 4(10x+2) = -27
-5x + 40x + 8 = -27
35x + 8 = -27
35x = -35
x = -1
now solve for 'y':
y = 10(-1) + 2
y = -10 + 2
y = -8
-5 ( x - 1 ) - x + 1 = -18
Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
Answer:
x=-4
Step-by-step explanation:
-5 ( x - 1 ) - x + 1 = -18
-5x+5-x+1=-18
6x+6=-18 <- -6 from both sides
6x=-24 <- divide 6 by both sides
x=-4

What is the equation of the line?
A. Y=1/2x-3
B. Y= -3x+1/2
C. Y=-3x+6
D. Y= 6x-3
Answer:
A
Step-by-step explanation:
y=mx+b
- m is your slope
- b is the y-intercept
if you look at your graph you can see the y-intercept is -3 because its on the y-axis
for the slope you do rise/run

Answer: x = 90°, therefore 3x = 270°
Step-by-step explanation:
The null space on the left of the shape is a 45-45-90 triangle. Since the internal angle is therefore 90°, 3x = 360°-9°, solving for x this yields x= 90°.

Determine whether or not the relation is a function. Please help asap
Answer:
A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function
Step-by-step explanation:
Find f(-2) and g(5)
f(x)=-2x³-5 g(x)=-4x+2
Answer:
f( -2) = 11
g(5) = - 18
Step-by-step explanation:
#1. Solving for f(-2)We're given a function "f" such that when it accepts a variable x, it's output, f(x), is:
[tex] \boxed{ \mathsf{f(x) = - 2 {x}^{3} - 5}}[/tex]
The value of f(x) depends upon what value of x is being inserted.
If x = -2
All the places taken by x will be given to -2
[tex] \implies \mathsf{f( - 2) = - 2( { - 2}^{3} )- 5 }[/tex]
(-2)³ is the cube of (-2) with -8 as it's result
[tex] \implies \mathsf{f( - 2) = - 2( { - 8}^{} )- 5 }[/tex]
when there's no operating sign between two numbers from different origin, they're multiplied
[tex] \implies \mathsf{f( - 2) = 16 - 5 }[/tex]
[tex] \implies \mathsf{f( - 2) = 11 }[/tex]
That gives us the value of f(-2) :
11
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#2. Solving for g(5):Here's another function, "g", taking x as input and giving us an output g(x), such that:
[tex] \boxed{ \mathsf{g(x) = - 4x + 2}}[/tex]
If x = 5
All the positions taken by x will be given to 5:
[tex] \implies \mathsf{g(5) = - 4(5) + 2}[/tex]
no sign between two numbers from different origin results in their product.
[tex] \implies \mathsf{g(5) = - 20+ 2}[/tex]
[tex] \implies \mathsf{g(5) = - 18}[/tex]
Thus, the value of g(5) is:
-18
To convert miles per hour to feet per second, which conversion factor would not be used?
1 hr60 min
1 hr60 min
1 min60 sec
1 min60 sec
5280 ft1 mi
5280 ft1 mi
1 mi
5280 ft
I'm doing this right now too :)
You start by writing the original numbers given into a proportion, which would be
miles
_____
hours
Then you have to convert the top unit, miles, into feet. You have to use the rate 1mile:5280 feet. You write that as a proportion too.
miles 1
_____ = ___
hours 5280
Next, you have to add a conversion rate for changing the hours into seconds. You'd use the rate 1 hour: 60 seconds.
miles 1 60
_____ = ___ = ____
hour 5280 1
Then you'd cross multiply to solve.

When x² is divided by (x – 3), the quotient is 12 and the remainder is 1. Find the
possible values of x
Answer:
Posible answers can be x=7 or x=5
Step-by-step explanation:
A box contains 6 black pens, 4 blue pens, and 7 red pens. Without looking, Clarissa randomly picks a red pen out of the box. If she chooses another pen out of the box without replacing the first one, what is the probability that she will pick a red pen both times? Write your answer as a percent rounded to the nearest whole.
Answer:
37.5%
Step-by-step explanation:
without replacing 7 becomes 6 so
6+6+4=16
and you have 6 red pens in the box so. 6/16 as a decimal is 37.5%

solve 6y + 8y =17 + 81
Answer:
y= 7
Step-by-step explanation:
6y + 8y =17 + 81
Combine like terms
14y = 98
Divide by 14
14y/14 = 98/14
y =7
Answer:
y=7
Step-by-step explanation:
Add 17 and 81 which is 98
then add 6y and 8y because they are also like terms which is 14y
now you have 14y = 98
then divide by 14 on both sides to get y by itself
then you will need to do 98/14 which is 7
answer is y=7
Which statement about the following equation is true. 2x^2 -9+2=-1
Step-by-step explanation:
2x² - 9x + 2 = -1
2x² - 9x + 3 = 0
D = b² - 4ac
D = (-9)² - 4.2.3
D = 81 - 24
D = 57
D > 0 , so there are two real roots
Option → C
_________
[tex] \: [/tex]
2x² - 9x + 2 = -1
2x² - 9x + 2 + 1 = 0
2x² - 9x + 3 = 0
a = 2 b = -9 c = 3Soo :
D = b² - 4ac
D = (-9)² - 4(2)(3)
D = 81 - 4(6)
D = 81 - 24
D = 57
Option (C.)

Answer:
B
Step-by-step explanation:
Let's eliminate the incorrect answers. C and D are incorrect, since anything to the power of 0 is equal to 1. A is incorrect, because -1 * -1 = 1 since the negatives cancel out. B is correct, because -1*-1*-1*-1*-1 has an odd number of negatives, and thus you are left with -1 instead of 1. Therefore, the answer is B.
Alejandra states that ax+ b= a(x+ c), given a, b, and c are not equal to 0. What must be the value of c for Alejandra's statement to be true? (Hint: Solve for c.)
Answer: c = b/a
Step-by-step explanation:
ax+ b= a(x+ c)
ax+ b= ax+ ac
b= ac
c = b/a

If two angles of one triangle equal in measure to two angles of another triangle then the third angles of the triangle
Answer:
Are also equal
Step-by-step explanation:
Say triangle A has the angles 30 and 60. triangle b also has those angles. Total angle of any triangle is 180 so 180-60-30 = 90 for triangle A and it is also the same for triangle b. Thus 90 = 90 angles are the same.

Plz HELP Directions: Write your own recipe for trail mix with a catchy name that will make
people want to eat it. You can also create a slogan, logo, or package design for the
mix. Your recipe must meet the following contest guidelines:
1. It must have at least five different ingredients.

• Prove that your recipe makes exactly 10 cups.
• Explain the most efficient method for measuring each ingredient using only
the following two measuring cups:
1
3
cup and

cup. You can use one or
both of the measuring cups. Note: Depending on the fractions that you chose
for your ingredient amounts, it may not be possible to create each exact
amount using only
