First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
If he decides to save 10% he decided to save 38.75 since 387.50×.10 is 387500 (move decimal 4 times to figure out what the percentage of 387.50 is since the $ already has 2 numbers after the decimals and so does .10 which =38.75 this is what he saves so subtract this from 387.50 to find out what he has left to spend
387.50-38.75= 348.75
Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
Answer:
J Monica is right
Step-by-step explanation:
Add three to both sides, divide by 4 you get x
4
