-7y-3x=21

-7y=21+3x

y=(21+3x)/-7

y=-3-3/7x

x inter

0=-3-3/7x

3=-3/7x

-7

(-7,0)

y inter

y=-3-(3/7)*(0)

y=-3

(0,-3)

Answer 2

I need to know How to evaluate the following expression for the given values of the variables.    4y^2t for y = -4 and t = -3      I'm having trouble working problem out and what the answer? Can you help?

Answer 3

x²+22x=0 ( complete the square.)

Answer 4

h(x)=x+2

grapgh h for x=-1,0,1,2

Answer 5

(2x2 -7x 6 ) (-3x2 7x)

Answer 6

could some one plese solve this problem and graaph it? y=2-4/3x

Answer 7

Answer 8

(4,7), y = 5X - 3

Answer 9

x=0 gives y intercept: -7y=21, y=-3; y=0 gives x intercept: -3x=21, x=-7.

Note how the line passes through the two intercepts.
