The best answer is C.
The subtraction quality pf equality states that when you subtract a the same number from both sides of an equation, the result is still equal.
Substitute the given into the function
f(-4) = |7(-4) - 3|
now solve
f(-4) = |-28 - 3|
f(-4) = | -31|
the absolute value of |-31| is 31
so,
f(-4) = 31
Hope this helps :)
You are not right on #46. Since he is going 50 miles in 50 minutes, that means that he is going a mile a minute. That means in an hour, he will have gone 60 miles. That means he will have been going 60 mph, so the correct answer is (4)
I cannot help you with 47 because you did not include the picture it shows.
