Question

how to rewrite the equation in function form.
7+7x=8

Answer 1

are you sure you posted the question correctly?

Answer 2

oops y+7x=8

Answer 3

y = -7x + 8

Answer 4

y = f(x) = -7x + 8

Answer 5

8y-16x=4

Answer 6

y = (4 +16x)/8

Answer 7

you just want to isolate y

Answer 8

ok, don;t understand the/8

Answer 9

it's a function becuase you can plug in for x and you'll get a function of x or a y

Answer 10

this is how you will plot points on xy plane graph

Answer 11

plug in for x coordinates and you get y coordinates

Answer 12

when they ask you to rearrange in function for then just solve for y lol

Answer 13

tell wether the ordered pair is a solution of the equation? 7=3x+4;(1,6)

Answer 14

yes it is

Answer 15

when you see (1, 6) that usually means (x, y)

Answer 16

plug in 1 for x then 7 = 3 (1) + 4

Answer 17

ok don't laugh at me heres another one, 7=-5x=2;(-3,-13)

Answer 18

you wrote it wrong i think

Answer 19

y=-5x=2

Answer 20

no

Answer 21

-5(-3) = 15

Answer 22

y = -13 so it's wrong

Answer 23

ok get it. how bout this 1. Your science class wants to visit an aquarium. Tickets cost $12.95/person. You also need to pay for the bus, which is $120. use the equation C=12.95p+120. where C is the total cost of the trip and p is the number of people going. If the final cost is $767.50, how many people went on the trip?

Answer 24

just plug in 767.50 for C

Answer 25

then solve for p

Answer 26

(767.50 - 120)/12.95 = p

Answer 27

o ok, thank you sooooo much

Answer 28

p = 50

Answer 29

ok good luck :)
