Question

.

Answer 1

I can give you the answer.

Answer 2

The first one will be y = -x +5 which can be either c or d

Answer 3

both of them are correct

Answer 4

it is A

Answer 5

x+y=5

Answer 6

look parallel mean same slope = -1,
so equation is y=-x+k
now this line should pass through 4,1.. so put them in equation to get k

Answer 7

The second one is c

Answer 8

Yeah, @popitree got the first one right.

Answer 9

I made a mistake.

Answer 10

The second one is c

Answer 11

perpendicular, so slope1xslope2= -1,
so, slope 2 =2/3,

y=2/3x+k, now solve for k

yeah C is correct one

Answer 12

Well (f+g)(x) = f(x) + g(x) = -2x + 8 +3x = x +8. Now substitute x.

Answer 13

Ok substitute (-1) for x, we got (f+g)(-1) = (-1) + 8 = 7

Answer 14

Yes

Answer 15

I guessed its A im not sure if im right

Answer 16

d

Answer 17

wait a is right

Answer 18

are you sure a is right?
