Answer:
b. 7x3 + 9x2 - 3x - 8
Step-by-step explanation:
Write the problem as a mathematical expression.
(4x3+6x2+2x−3)+(3x3+3x2−5x−5)
Remove parentheses.
4x3+6x2+2x−3+3x3+3x2−5x−5
Add 4x3
and 3x3
.
7x3+6x2+2x−3+3x2−5x−5
Add 6x2
and 3x2
.
7x3+9x2+2x−3−5x−5
Subtract 5x
from 2x
.
7x3+9x2−3x−3−5
Subtract 5
from −3
.
7x3+9x2−3x−8

Answer:
B. Exponential
Step-by-step explanation:
The annual wolf population in each year is
w = 500 500(0.9) 500(0.9)² 500(0.9)³ …
n = 1 2 3 4 …
The model is w = 500(0.9)ⁿ⁻¹.
This is an exponential model, because the independent variable is in an exponent.
Answer:
slope of y = -7 is 0
Step-by-step explanation:
y = any number forms a graph of a horizontal line
x = any number forms a graph of a vertical line
For any horizontal line , the slope is always 0
for any vertical line , the graph is always undefined
So for y =-7 we will get a horizontal line at -7 on t
the slope of horizontal line y=-7 is 0
