Step-by-step explanation:
The y-intercept is +4 for both lines, so only the third selection is appropriate. The lines appear to have a slope of magnitude less than 1, so ±1/2 seems about right.
(We expect at least one of the inequality symbols to include the "or equal to" case so there is no hole at x=0. Alas, it seems the third answer choice doesn't do that.)
Answer:
(nearest tenth)
Step-by-step explanation:
Given the distance formula,
, distance between (-4, 5) and (4, 0) is calculated as follows:
Let

Answer:
substitute 8 into x =(8-2)2
(6)2=12
Answer:
B 9, -9
Step-by-step explanation:
x^2 - 81 = 0
Add 81 to each side
x^2 = 81
Take the square root of each side
sqrt(x^2) = sqrt(81)
x = ±9
