Answer:
B. -5.
Step-by-step explanation:
fg(x) = (x - 1)(5x^2 + 19x - 3)
= 5x^3 + 14x^2 - 22x + 3
So fg(-4) = 5(-4)^3 + 14(-4)2 -22(-4) + 3
= -320 + 224 + 88 + 3
= -5.

Answer:
Hey there!
First, let's identify the point. We always go x axis first, then y axis, so the point is at (3, 8).
From the graph, we see that it means the tree is 8 feet tall and three years old.
Let me know if this helps :)
Answer:
Step-by-step explanation:
6x + 3y = -18
Taking 3 common from left side
so, 3(2x+y) = -18
2x+y = -18/3
2x+y = -6 (equation 1)
and, 7x + 7y = 0
Taking 7 as commom from left side
7(x + y) = 0
x + y = 0/7
x + y = 0 (equation 2)
now , by using elimination method
subtracting equation2 from equation1
2x + y - (x + y)= -6 - 0
2x + y - x - y = -6
x = -6
so, x = -6
substituting value of x in equation 1
2(-6) + y = -6
-12 + y = -6
y = -6 +12
y = 6
hence, the value of x = -6
and value of y = 6
