Answer:
216 + 9i
Step-by-step explanation:
Given: f(x) = 3x² + 3 + 3x
When x = -9, f(x) equals to;
3(-9)² + 3(-9 + 3(-9)
243 + 3(3i) - 27
243 + 9i - 27
216 + 9i

Step-by-step explanation:
2x ≥ 4
Divide by 2
2x/2 ≥ 4/2
x ≥ 2
-x+7<-6
Subtract 7 from each side
-x+7-7<-6-7
-x < -13
Divide each side by -1, remembering to flip the inequality
x > 13
y>-x+3
This is a line with slope -1 and y intercept 3
This is a dotted line since there is no equals sign and graph above
