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:

So, if we shrink the function -5x by a factor of 1/5, we get the function -x.
5^(2/3)=25^(1/3)
Third one ( the one below your selection)
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
Answer:
d. 21
Explanation:
Step 1 - Subtract 13 from both sides
x + 13 = 34
x + 13 - 13 = 34 - 13
x = 21
9.
9 squared is 81. 81+4=85. 85 is divisible by 5.
