Answer:
12 boys
Step-by-step explanation:
I believe the answer is 12 boys. I hope this helps!
Using derivatives, it is found that the x-values in which the slope belong to the interval (-1,1) are in the following interval:
(-15,-10).
<h3>What is the slope of the tangent line to a function f(x) at point x = x0?</h3>
It is given by the derivative at x = x0, that is:
.
In this problem, the function is:

Hence the derivative is:

For a slope of -1, we have that:
0.4x + 5 = -1
0.4x = -6
x = -15.
For a slope of 1, we have that:
0.4x + 5 = 1.
0.4x = -4
x = -10
Hence the interval is:
(-15,-10).

It would be answer choice A (10^5) because there are 5 10s in the problem
Here, we can formulate the slope-intercept equation from the point and the slope:
Slope = -4/-4 = 1
x1 = -2
y1 = 5
By point-slope form:
(y-y1) = m (x - x1)
(y-5) = 1(x +2)
y-5 = x +2
Simplifying to slope-intercept form:
y = x + 7
Therefore, the slope-intercept form would be y = x+7
I hope my answer has come to your help. God bless and have a nice day ahead!
