Your answer would be 4.
If we substitute in x = -8 and y = -4 into the expression, we get:
This then becomes:
=
= 4.
I hope this helps!
X divided by -7 is less than or equal too 8

Answer:
or approximately (0.544, 4.179)
Step-by-step explanation:
A function and its tangent lines intersect when their slopes are the same. Find the x-coordinate when the slope of f(x) is equal to 8/7 by taking the derivative of f(x):
Set equal to 8/7 and solve for x:
Therefore, will intersect at a point of tangency with a line of slope 8/7 at x=49/900. Plug in x=49/900 into
to get the y-coordinate:
⇒Answer: (49/900, 3761/900) or approximately (0.544, 4.179)
