W+D=659
W=D-91
---------------------------
(D-91)+D=659
D-91+D=659
2D=750
D=750/2=375
------------------------------
W+375=659
W=284
------------------------------
So the dryer had cost $375 and the washer had cost $284.
Answer:
5(2x(2x + 3) - 3 ( 2x +) or 5(2x -3) (2x + 3)
Hello!
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
First, let's find the y-intercept. This is where the line hits the y-axis. Therefore, it hits at 4 on the y-axis, so our y-intercept is 4.
To find the slope, let's find 2 points on our line. Let's use (0,4) and (2,5). We divide the difference in the y-values by the difference in the x-values as shown below.

Therefore, our slope is 2.
Now we plug these values into our equation.
y=2x+4
I hope this helps!
