Answer:
B
Step-by-step explanation:
30 are unusable in 200. So how many are unusable in 17,000??
<em>We can set up a ratio and figure out the answer right away! Let x be the number of unusable bolts in 17,000, so we can write:</em>
<em>
</em>
<em />
<em>THus, number of unusable bolts is 2550. B is right.</em>
F(x) = 2x^2 - x
if x=-3
f(-3) = (2*(-3)^2) - (-3)
f(-3) = (2*9) + 3
f(-3) = 18 + 3
f(-3) = 21
