Answer 4

Just substitute the value of x into the equation
y = 3(-0.8) + 1
=?

substitute your x with its value , then solve

Answer 6

I dont get it?

Answer 7

Replace x in the equation with the x = value in the question.

Answer 8

y = 3x + 1
and x = -0.8
so y = 3(-0.8) + 1

Answer 9

haha ow come on, Incognlto already did it for you! just need to solve it :) coz we're teaching you how to fish, & not giving the fish to you directly :)

Answer 10

I get it now thanks

You're welcome :)

Answer 12

the value of x when y = 8.2?

Answer 13

Solve the inequality 4x-3<7?

Answer 14

Now you need to solve for x, so put x on one side and all the other values on the other. What do you get?

Answer 15

That works for both, but lets just do the first one now.

Answer 16

Come on, 8.2 = 3(x) + 1...
What next?
