X = multiple choice and y = essay
x + y = 20.....x = 20 - y
3x + 11y = 100
3(20 - y) + 11y = 100
60 - 3y + 11y = 100
-3y + 11y = 100 - 60
8y = 40
y = 40/8
y = 5 <=== 5 essay questions
x = 20 - y
x = 20 - 5
x = 15 <== 15 multiply choice
Answer:
f(-3) = 21
Step-by-step explanation:
We "evaluate" the function f(x)=2x^2+3 at x = -3 by subbing -3 for x in f(x)=2x^2+3:
f(-3) = 2(-3)^2 + 3 = 2(9) + 3 = 21.
Thus, f(-3) = 21
