Answer:
x=50
See below for word problem.
Step-by-step explanation:
While shopping, you spend $125 before tax. You buy 3 dresses at the same price each and receive a $25 discount. How much is the price of each dress?
3x-25=125
3x=125+25
3x=150
x=50
Answer:
![y=-2x+12](https://tex.z-dn.net/?f=y%3D-2x%2B12)
Step-by-step explanation:
To write the equation of a line, find the slope between two points. Substitute two points into the slope formula. If the equation has an x-intercept of 6 then the line passes through the point (6,0). Use (6,0) and (4,4) in the formula.
![m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-0}{4-6} =\frac{4}{-2} =-2](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%3D%5Cfrac%7B4-0%7D%7B4-6%7D%20%3D%5Cfrac%7B4%7D%7B-2%7D%20%3D-2)
Since m = -2, substitute its value and the point (6,0) into the point slope form. Then simplify.
![y-y_1 = m(x-x_1)\\y-0 = -2 (x-6)\\y=-2x+12](https://tex.z-dn.net/?f=y-y_1%20%3D%20m%28x-x_1%29%5C%5Cy-0%20%3D%20-2%20%28x-6%29%5C%5Cy%3D-2x%2B12)
