The anwer plus working is 6668/4=151.55
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
x = 50
m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
Problem 3
This is not an exponential function. If you were to graph this out, you would see a parabola forming. Or at the very least, a parabolic-like curve forms. An exponential curve only increases or only decreases for the entire domain. However, in this case, we have an increasing portion, and then it decreases.

Problem 4
This is an exponential function. Each time x increases by 1, y is multiplied by 4. The equation that models these points is y = 4^x. Note how the function is strictly increasing and there are no decreasing portions mixed in.
Answer:
Slope =
or -1
y = 6
Step-by-step explanation:
The equation given (y = 6 - x) is the same as saying
y = -1x + 6
Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be
Slope =
or -1
While the y-intercept would be
y = 6 - x
y = 6 - 0
y = 6
96.5 times 2.54
the answer is 245.11
