Question

which of the followingis a solutuion to the inequality y>3x-4?
a)(2,2)
b)(-1,-9)
c)(1,1)
d)(0,-6)

Answer 1

Did you know that if you plug in the numbers, you could just check. (x,y) = (.. , .. ). Throw them into the inequality and see which ones work. If you end up with something like 3 > 4, then that one didn't work...

Answer 2

yea i dont even no how to do the problem....

Answer 3

Take (b) for example. it's given you (-1, -9). This is saying that it wants you to try x = -1, and y = -9.

Now have a look at the inequality, with those numbers for x and y.

y = -9.

3x-4 = 4 * (-1) - 4 = -4 - 4 = -8.

Now, is y > 3x-4?

No. So (b) is not a possible solution.

Do the same with the rest.

Answer 4

can i just have the answer bec i have 30 mins left t take this timed test an i have a whole bunch more problems to do..

Answer 5

In the time it took you to type that, you could have solved it yourself, rather than thinking that a stranger might do it all for you for some unknown reason.

Answer 6
