Answer: see below...
Step-by-step explanation:
a)
48 = 30%
100/30 = 10/3
48 x (10/3) = 160
$160 = 100%
b)
160 - 48 = $112
Answer:
b
Step-by-step explanation:
Y = -2x + 4
y = x² + 4x + 13
-2x + 4 = x² + 4x + 13
<u>+ 2x + 2x </u>
4 = x² + 6x + 13
<u>- 4 - 4</u>
0 = x² + 6x + 9
x = <u>-(6) ± √((6)² - 4(1)(9))
</u> 2(1)<u>
</u> x = <u>-6 ± √(36 - 36)
</u> 2<u>
</u> x = <u>-6 ± √(0)
</u> 2<u>
</u> x = <u>-6 ± 0
</u> 2<u>
</u> x = <u>-6
</u> 2
x = -3
y = -2x + 4
y = -2(-3) + 4
y = 6 + 4
y = 10
(x, y) = (-3, 10)
The y - coordinate of the solution is 10.
