Answer:
y = -1/2 x + 1
Step-by-step explanation:
(-2, 2) and (4, -1) are points of the linear function, that will be described as:
y = ax + b
setting x=-2, y=2:
2 = -2a + b, so b = 2 + 2a
setting x=4, y=-1:
-1 = 4a + b ⇒ -1 = 4a + 2 + 2a ⇒ -3 = 6a ⇒ a = -1/2, b = 1
y = -1/2 x + 1

Seth earns $20 a day and $2 for each ticket he sells at the local theatre. Write and solve an inequality that can be used to find how many tickets he must sell in a day to earn at least $85.
Write an inequality.
Answer:
2x + 20 >_ 85
Step-by-step explanation:
In this equation, the 85 represents how much he needs to make. The greater than or equal to symbol is basically stating that he needs to make an amount greater than or equal to 85. Our variable, x, will tell us how many tickets he needs to sell, and the 2 represents how much each ticket sells for. 2x is just saying that each ticket sells for 2 dollars. The 20 is how much he makes on a daily basis without the ticket sales. We have to include that in the 85. That's where our equation comes from :)

If I were to simplify the expression 10-19 would my answer be a positive or a negative an why
Answer:
It would be negative. 10 subtracted by any number higher then 10 will always be negative. Make a number line and go backwards 19 if you need the help.
Step-by-step explanation:
Answer: It will be negative because 19 is greater than 10 and 19 itself is being subtracted from 10.
Step-by-step explanation:
10-19 is equal to -9.
An example is using the number line to plot the solution, you will start from 10 and move backwards 19 units because you are subtracting 19 from 10. If a bigger number is being subtracted from a smaller number, the solution will be always negative.
7(3 + 4y) - 15y = 73
( Multi-step equations)
show work please and thank you
Answer:
Step-by-step explanation:
7(3+4y)-15y=73
21 plus 28y-15y=73
21 plus 13y = 73
13y=51
y=4
Step-by-step explanation:
Step 1: Multiply the 7 into the bracket.(make sure that your signs are correct)
Step 2: Minus the 21 from the 73.( Because when you take a value over the equal sign the value's sign changes)
Step 3: Minus 15y from 28y.
Step 4: Divide 52 by 13( because when you take the 13 over it divides ,because on the other side lf the equal the 13 multiples with the y)

How can the statement be rewritten as a conditional statement in if-then form? Lines on a coordinate plane are perpendicular if they have opposite reciprocal slopes. If lines on a coordinate plane have opposite reciprocal slopes, then they are perpendicular. If lines are on a coordinate plane, then they are perpendicular. If lines are on a coordinate plane, then they have opposite reciprocal slopes. If lines have opposite reciprocal slopes and are perpendicular, then they are on a coordinate plane.
Answer:
The first option. "If lines on a coordinate plane have opposite reciprocal slopes, then they are perpendicular."
Step-by-step explanation:
It is the only one that makes sense, tbh. But, it includes the proper "if-then" form like the question requests it have. It also incorporates all aspects of the original statement-
a.) lines on a coordinate plane
b.) perpendicular
c.) opposite reciprocal slopes.

An equation is shown below: 5(2x-8) +15 = -15 write the steps you will use to solve the equation and explain each step
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
Answer:
x=1
Step-by-step explanation:
First youd distribute the 5 to the 2x-8 so that way you can combine like terms and make the equation smaller
10x - 40 + 15 = -15
combine the -40 and 15
10x - 25 = -15
add 25 to both sides to get 10x by itself on the one side. you have to add 25 to the -15 because the two sides must stay balanced
10x = 10
divide by 10 to get x by itself. you must divide since x is being multiplied by 10
x=1
A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave
$10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is
A'Reana's weekly allowance?
Answer:
Answer: A'Reana's weekly allowance is $100
Step-by-step explanation:
Backward Solution
To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.
The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.
That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45
This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.
Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100
Answer: A'Reana's weekly allowance is $100

Change the positions of vertices A, B, and C to create a triangle of your choice. Does the relationship between and change when the vertices of ∆ABC are modified? Explain.
10+
Answer:
No, there is no change in the relationship. The slopes of AC and DE continue to be equal, and the length of DE remains half of the length of AC.
Step-by-step explanation:
The answer is from Plato. I hope this helps :)
Answer:
No, the connection has not changed. The slopes of AC and DE are still equal, and the length of DE is still half that of AC.

Step-by-step explanation:
A man wants to cut down a tree in his yard. To ensure that the tree doesn't hit anything, he needs to know the height of the tree. He measures his distance from the tree at 10 meters and angle of elevation to the tree at 54 degrees. What is the height of the tree to the nearest tenth of a meter?
Answer:
the height of the tree to the nearest tenth of a meter is 13.8 meters
Step-by-step explanation:
The computation of the height of the tree is shown below:
Given that
Distance from the tree is 10 meters
And, the angle of elevation of the tree is 54 degrees
Now here we used the trigonometry
[tex]tan \theta = \frac{Height}{distance} \\\\tan 54^{\circ} = \frac{height}{10}[/tex]
So, the height is
= 10 × 1.38
= 13.8 meters
hence, the height of the tree to the nearest tenth of a meter is 13.8 meters

D. If you subtract the sum of the areas of the four triangles from the complete figure in both steps, the remaining areas are equal.
Answer: B, the area of interior square in step 2 is greater than the combined area of the two interior squares in step 1.
Step-by-step explanation: I took the quiz and got it right
The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1. Then the correct option is B.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

Bridget goes to the mall and buys a shirt for $15.50, a pair of jeans for $32.00, and a belt for $24.30. She has a coupon and ends up getting $14.36 off her purchase. What percent off was her coupon for?
Answer:
20%
Step-by-step explanation:
Cost of Shirt = $15.50
Cost for a pair of jeans = $32.00
Cost for a belt = $24.30
Total cost = $15.50 + $32.00 + $24.30 = $ 71.8
Given that, coupon discount = $14.36
To find:
The percentage off on the coupon.
Solution:
The percentage off will be calculated on the total cost.
[tex]\text{Percentage\ off} = \dfrac{Coupon\ discount}{Total\ Cost}\times 100\\\Rightarrow \text{Percentage\ off}= \dfrac{14.36}{71.8}\times 100\\\Rightarrow \text{Percentage\ off} = 0.2\times 100\\\Rightarrow \text{Percentage\ off} = \bold{20\%}[/tex]
Therefore, the answer is:
20%
