2. 3 1/3 cups water to 1 cup concentrate
Step-by-step explanation:
1. You have done the math. Copy your answer into the blanks that are waiting for it.
9/20 hours on math for 1 hour reading
__
2. 1 2/3 ÷ 1/2 = 5/3 × 2/1 = 10/3 = 3 1/3
3 1/3 cups of water to 1 cup of juice concentrate
-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
F(x) = (x + 3)²
g(x) = f(x) - 7.
g(x) = (x + 3)² - 7
g(x) = (x + 3)(x + 3) - 7
g(x) = x*x + x*3 +3*x + 3*3 - 7
g(x) = x² + 3x + 3x + 9 - 7
g(x) = x² + 6x + 2
