Take the equation: y = 520 + 14x and put each value from the table in for x and y.
100 = 520 + 14 * -30
100 = 520 + -420
100 = 100 When we get an answer like this where the numbers on both sides of the equation match, we know that this (x,y) point is a part of the solution to the function.
So, you would work through each line in the table. If they are all like the one above, the answer is Yes. If not, it is no.

Answer:
0.15
Step-by-step explanation:
Answer:
B. The x-intercept of function A is less than that of function B.
Step-by-step explanation:
Both functions have y-intercepts of -1. Function A has a slope of 2, while function B has a slope of 1. Since Function A has a steeper slope, its x-intercept will be closer to x=0 than that of Function B.
___
The x-intercept of Function B is given as (1, 0). The x-intercept of Function A can be found by solving for x when y=0:
... 0 = 2x -1
... 0 = x - 1/2 . . . . divide by 2
... 1/2 = x . . . . . . . the x-intercept is (1/2, 0), so is less than (1, 0)
