Answer:

x=4

Step-by-step explanation:

think of the equation like this: you have to do the inverse(opposite) operations so for adding you would subtract it. So for the adding 3 you would subtract it from both sides of the equation and get X=4

Please help ASAP!! I'm really struggling at this problem. Will give 10 points & to the brainliest!
Jlenok [28]

Answer: B

Step-by-step explanation:

To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.

Pls help! I need help with a and c I did b already!
laila [671]

Answer:

A= y= -2x+7.

B= y= -\frac{3}{2}x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= -\frac{3}{2}x+ 6

-\frac{3}{2} is the slop and 6 is the y intercept.

Hope this helps :)
