Answer:
f(x)=8x-25
Step-by-step explanation:
A line perpendicular to y = -2x + 5 will have an equation in the form of:
y = (1/2)x + b
Since the graph must intersect (-2,9), we plug in this point to solve for b.
9 = (1/2)*(-2) + b
9 = -1 + b
10 = b
So the equation is:
y = (1/2)x + 10
The answer is A.
C would be the correct answer. You caanot multiply just one part of an equation, you must multiply the whole thing. All of the other steps follow this rule, so C is an incorrect step, and is therefore the correct choice.
Hope this helps!

Answer:
sin -1 degrees.
Step-by-step explanation:
sin (A - B) = sin A cos B - cos A sin B
Therefore sin 9° cos 10°- cos 9º sin 10° = sin (9 - 10)
= sin -1 degrees.
