The larger triangle is 5x the size of the smaller triangle.
5*5=25 and 3*5=15
So I figured that would be the same for the 3x+8 side and the 4 side.
4*5=20, So you'd set 3x+8 equal to 20 and solve from there.
3x+8=20
-8 -8
x=4
Answer:
When we have a function f(x), the values of x at which the function is not differentiable are:
1) values at which the function is not "soft". So if we have a really abrupt change in the curvature of the function, we can not differentiate in that value of x, because in those abrupt changes there are a lot of tangent lines to them.
One example of this is the peak we can see at x = -4
Then we can not differentiate the function at x = -4
2) When we have a discontinuity.
If we have a discontinuity at x = x0, then we will have two possible tangents at x = x0, this means taht we can not differentiate at x = x0, and remember that a discontinuity at x = x0 means that:
f(x0₊) ≠ f(x0₋)
where x0₊ is a value that approaches x0 from above, and x0₋ is a value that approaches x0 from below.
With this in mind, we can see in the graph a discontinuity at x = 0, so we can not differentiate the function at x = 0.
Answer:
x=-4
Step-by-step explanation:
x+12+x+16=20
2x=20-28
x=-8/2
x=-4

Answer:
33
Step-by-step explanation:
396/x - 10 = -22
add 10 to each side
396/x = -12
multiply both sides by x
396 = 12x
divide both sides by 12
33 = x
