Answer:
0.83r + 0.91
Step-by-step explanation:
-0.17r + 0.91 + r
Combine like terms (so, that would be r)
0.83r + 0.91
(x + 8)(x - 5)
= x (x - 5) + 8(x - 5)
= x² - 5x + 8x - 40
= <u>x²</u><u> </u><u>+</u><u> </u><u>3</u><u>x</u><u> </u><u>-</u><u> </u><u>4</u><u>0</u><u> </u><u>(</u><u>a)</u>
Answer:
b. 8
Step-by-step explanation:
12/30 = x/20
x = 12/30 × 20
x = 8
Answer:
y = -2
Step-by-step explanation:
The line that is perpendicular to y-axis will be a horizontal line so it's slope is 0 => y = 0x + b or y = b
Using (5,-2) => -2 = b => b = -2
then y = -2
It would be: 18/15 * 100 = 1800/15 = 120%
