Answer:

17.5

Step-by-step explanation:

y=kx

35=140k

k= 35/140

k= 1/4

y=1/4X

when X=70

y= 1/4*70

y= 17.5

ANEK [815]

Answer:

100

Step-by-step explanation:

well, you can just use a calculator, or your mind if that's possible, to solve this.

at least, what i think you're asking.

400 × 0.25 = 100.

this one is extra easy because you should know that 25% is a quarter, and 400 can just be divided by 4 to get your answer.

Let f(x)= 12/4x+2 find f(-1)

denis23 [38]

F(x) = 12/(4x+2)

x = -1

f(-1) = 12 / [4(-1)+2]

f(-1) = 12 / (-4+2)

f(-1) = 12 / -2

f(-1) = -6

Hey there! I'm happy to help!

Lines that are parallel have the same slopes because they are increasing or decreasing at the same rate and therefore will never bump into each other.

We see that y=2 has a slope of 0 because there is no x that we can see in the equation. This is just a flat line.

If the line we are looking for is flat; it stays at the same y-value the entire time. We see that the y-value for this line of ours is -6. Therefore, the answer is C. y=-6.

I hope that this helps! Have a wonderful day!
