Answer:
(4,9) is in quarter I and (4,-9) is in quarter IV of the graph. (4,-9) is the point (4,9) reflected over the x-axis. they are similar bc both have 4 as their x coordinate.
Step-by-step explanation:
We can use the points (-2, -5) and (18, -5) to solve.
Slope formula: y2-y1/x2-x1
= -5-(-5)/18-(-2)
= 0/20
= 0
Best of Luck!
20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
Answer:
Step-by-step explanation:
The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.
Perform the indicated multiplication, obtaining:
8x - 20 = 9x - 18.
Then combine like terms: -2 = x, or
x = -2.
To complete the formal check, substitute -2 for x in the first equation. This results in:
(1/3)(-4 - 5) = (3/4)(-2 -2), or
-3 = -3
... which is obviously true.
