You should plug the x and y values into the original equations to get your b value. You should get a b value of 7. Your new equation should be y=2x+7
Answer:

Step-by-step explanation:
The given polynomial equation is

We perform the synthetic division as shown in the attachment by dividing by x-2.
This gives a remainder of 0 and a quotient of

This means the polynomial equation becomes:

We factor the quadratic term by splitting the middle term;


Collect common factors again:

The solution is:

Answer:
Its either 300 or 315
Step-by-step explanation:
Mainly because 20 ×15= 300 but the triangles on the side, I can't figure it out. I eliminated 82 and 420, 420 mainly because I got it wrong and 82 doesn't make sense.
Answer:11x
Step-by-step explanation:
W = 7/15 L
w = 56
56 = 7/15 L
56 x 15/7 = 7/15 x7 L
L = 120
