Answer:
37
Step-by-step explanation:
h(x) = x² - 5x + 7
First let's just look at the h(-8) before we add the 1/3. Substitute the -8 into the place of x.
h(-8) = (-8)² - 5(-8) + 7
h(-8) = 64 + 40 + 7
h(-8) = 111
Now let's add the 1/3.
1/3 · h(-8) = 1/3 · 111 = 37
The answer is 37.

Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6
Let's solve this system of 2 equations:
x + y =63
x + 0.1 y = 12.6
Solving it will give you:
x= 7 liters at 100%
y = 56 liters at 10%
The answer is A because if you divide 30 by 6 you get 5 and if you divide 48 by 6 you get 8, that is your ratio 5:8, I hope this helps!
