Answer:

x = 1/2

Step-by-step explanation:

8(-2x+1) =0

Divide each side by 8

-2x+1 = 0

Add 2x to each side

-2x+1+2x = 2x

1 = 2x

Divide by 2

1/2 = 2x/2

1/2 =x

Answer:

1/2

Step-by-step explanation:

8(-2x+1)=0

Use distributive property first

-16x+8=0

Subtract 8 on both sides

-16x=-8

Divide both sides by -16 to get x by itself

x=0.5

Which is also equal to 1/2

Therefore, x is equal to 1/2

F(x) = -5x; vertical shrink by a factor of 1/5
tatiyna

In order to vertically stretch a function by a factor k, we have to multiply the function expression by k.

So, in order to stretch the function by a factor of 1/5, we simply have to multiply:

f(x) = -5x \implies g(x) = -5x\cdot\dfrac{1}{5}=-x

So, if we shrink the function -5x by a factor of 1/5, we get the function -x.

What value of c makes the equation true?<br><br><br><br> −3−3/4(c−4)=5/4
Anuta_ua [19.1K]
C = -5/3 = -1 2/3



Write down the equation and solve for c

-3 - 3/4(c-4) = 5/4



Distribute the 3/4

-3 -(3/4)c + 3 = 5/4



Perform the addition of -3 and 3

-(3/4)c = 5/4



Divide both sides by -(3/4)

c = 5/4 / (-3/4) = 5/4 * (-4/3) = -20/12 = -5/3



So the value of c is -5/3. Let's verify it.

-3 - 3/4(-5/3 - 4) = x



Distribute the -3/4

-3 - (3/4)(-5/3) + (3/4)4 = x

-3 +15/12 + 3 = x



Combine terms

15/12 = x



Simplify

5/4 = x
