It would be 90 degrees. :)
Answer:
I don't think that there is two same results. sorry I couldn't help
Step-by-step explanation:
for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4
and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.
for III it should be y = 8 or 4
Ok so slope is y2-y1/x2-x1. the question is asking you to find the value of x1 that will make the slope 7. plug in your coordinates to get (7-(-7))/(4-s)=7, then you simplify to get 14/(4-s)=7, multiply both sides by (4-s) to get 14=7(4-s), divide both sides by 7 to get 2=4-s, and then solve to get that s=2. hope this helps!
