So the whole goal of this is to get the variable (z) all by itself on one side with a coefficient (the number in front of the variable (z)) of one. All you have to do is add seven to each side to get z alone and then divide by two:
2z-7< or equal to 1
+7
2z< or equal to 8
/2
z< or equal to 4
Answer:
if you plug in (positive) five for x, the equation will equal 8
Step-by-step explanation:
f(5^2 - 5x + 8) = 8
please message me if you have any questions :) maybe mark me brainliest answer ??
Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x
X ÷ 5 if x = 5 is 1
five to the power of one is 5
any number ÷ by 0 is 0
yes
