Question

If f(x) = x + 5, find f(−9).

14

4

−14

−4

Answer 1

replace every copy of x with -9, then evaluate

Answer 2

plug in -9:
f(-9)=(-9)+5

Answer 3

Please help with these questions. I will try to answer as many as i can but am stuck on this one.

Answer 4

Thanks.
-4

Answer 5

correct

Answer 6

Select the equations that are parallel and perpendicular to y = −3x − 1 and that pass through the point (3, 1).

parallel: y = −3x + 6
perpendicular: y = one over threex + two and two thirds

parallel: y = −3x + 10
perpendicular: y = one over threex

parallel: y = negative one over threex
perpendicular: y = −3x

parallel: y = one over threex + 1
perpendicular: y = 3x − 1

Answer 7

I think that it is the top one.

Answer 8

you need to make sure the point (3,1) is on both lines

Answer 9

y = -3x + 6

1 = -3*3 + 6 ... plug in (3,1)

1 = -9 + 6

1 = -3 ... FALSE, so (3,1) is NOT on the line y = -3x + 6

Answer 10

Ok. I got it.
