A=(2x+1)/B
C=(5x-14)/B
AC=(2x+1)/B * (5x-14)/B
AC=(10x² - 23x - 14)/BE
Answer:
The two graphs are perpendicular
Step-by-step explanation:
The slope of the first one is the reciprocal of the second. Also I graphed it.
Answer:
x+7
Step-by-step explanation:
Remove Parentheses

Calculate
Answer:
The answer is 2.
2 since 6/4=3/2
Step-by-step explanation:
Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)
If y=kx then y/x=k.
So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.
So we are going to solve this proportion:

Again I put y/x from each point. They should have same ratio because this is a direct variation.
Cross multiply:


Divide boht sides by 6:
