Which equation has (100, –100) as a solution?
A. y = 0.1x – 99
B. y = – x – 100answer
C. y = x
D. y = –x
Answer:
D
Step-by-step explanation:
Ok so you just need to plug in the points
A. -100= 0.1(100)-99 (FALSE)
B. -100= -100-100 (FALSE)
C. -100= 100 (FALSE)
D. -100= -(100) (TRUE)
Why did I plug in the numbers? Because its (x,y) meaning 100=X and -100=Y. So just plug them in to know the correct answer.

Answer:
82.36
Step-by-step explanation:
284 x 0.29 = 82.36
Have an amazing day!
PLEASE RATE!
Answer:
Step-by-step explanation:
Alright, so the answer is $400. So we know that $284 is a discount on the whole price, 29% off. So 284 is 71% of the whole price, 100%-29%=71%. So then I just divided 284 by 71 and got 4. 284/71=4. Because I divided it by 71, $4 is 1% of the whole price, so I multiplied 4 by 100 and got $400 as the original price. You can just do this equation with any type of calculator, also please select my answer as the brainliest.✌

Answer:
First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex]

im so confused pls help
Step-by-step explanation:
for some reason the equation at the top says 7(x+2) but both of the equations at the bottom say 7(x-2)... I'm just going to do 7(x-2)
Emmanuels Work:
7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7
x-2=13
add 2 to both sides
x=15
I only know the first one with the method Emmanuel is doing sorry ;(
at least there's a guide in this image
