F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==
It's asking you what percent of 500 is 430, and you can answer that by first dividing 500 by 100 to find 1%, which is 5, and then dividing 430 by 5, which is 86%, which is your answer. To fill in your sheet, you put the 430 in the left box and the 500 on the right. I hope this helps!
<span>√p − 1 − √p = 1
- 1 = 1 (</span>√p is canceled out)<span>
since -1 cant equal 1 so there's no solution</span>
X+2 < 7
Subtract both sides by 2
x < 5
Any value where x was less than 5 would be correct.
