Answer:-5/2
Step-by-step explanation:
When there are two points given like above use this formula.
y2-y1/x2-x1
(The 1 and 2 is gonna be on the bottom right. It represents the number of y and x as there is two sets of (x,y)
Answer:
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Step-by-step explanation:
Given expressions are;
4(5x-8) and 2(4-x)
For 4 more than the second expression, we will add 4 with second expression.
4(5x-8) = 2(4-x) + 4
20x - 32 = 8 -2x +4
20x + 2x = 12 + 32
22x = 44
Dividing both sides by 22
![\frac{22x}{22}=\frac{44}{22}\\x=2](https://tex.z-dn.net/?f=%5Cfrac%7B22x%7D%7B22%7D%3D%5Cfrac%7B44%7D%7B22%7D%5C%5Cx%3D2)
Hence,
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
The answer to your questions is 3.12
B=-3
because you divide 27 by -9 to get y by its self
