Question

If the graph of 3x-5y=s passes through points (3,1) and (5,r) what is the value of r??

a)2
b) 11/5
c) 16/5
d) 4
e) 25/4

how did you do this?

Answer 1

1) Substitute (3,1) into the equation of the graph to get a value of s.
2) Substitute the value of s into the 3x-5y=s equation to get a general form of the equation.
3) Substitute (5,r) into the equation to find for r.

Answer 2

ohhhh so b? :D

Answer 3

THANK YOU THANK YOU SOSOSO MUCH

Answer 4

Yea

Answer 5

can u help me with another?

Answer 6

if g(x)= f(x)+k and the graph of g(x) (greater than or equal to ) 0 for all vlaues of x, which of the following CANNOT be the value of k?

3
4
5
6
7

Answer 7

those are the choices

Answer 8

hellooooo???? :(

Answer 9

oh nvm LOL i see you typingg

Answer 10

when g(x) is >= 0, means that f(x) + k is >= 0 also.

Will you have expressions of fx and gx?

Answer 11

no

Answer 12

is the answer 7???

Answer 13

herro???
