Answer: The maximum value of f(x) is when x = 225.
The equation given is an upside down parabola. Therefore, the maximum height of the parabola is at the vertex.
To find the vertex when the equation is in standard from, we can use "-b/2a" to find the x-value.
Our expression is:
-40/-2 = 20
(-5,-3), Parallel to -3x - 7y = 10, Put in slope-intercept form.
So, we must find the slope of this first.
-3x - 7y = 10
Add 3x to both sides.
-7y = 3x + 10
Divide both sides by -7.
y = -3/7x - 10/7
So, our slope is -3/7.
Remember, if you're looking for a line that is parallel to something, the slopes always stay the same.
*Also remember that slope-intercept form is y = mx+b*
Where m = slope, and b = y-intercept.
We have the points (-5,-3) so our y-intercept is -3.
Our slope is -3/7.
So, simply plug in those values into the slope-intercept form equation! :)
y = mx + b
y = -3/7x - 3

Answer:
The measure of the outside angle is the sum of the two inside angles:
68+52=120
Or you could do it the long way and find the third angle inside the triangle then do 180 minus that but this is easier.
