Answer: James will save $3 for 18 weeks before he can buy the telescope
Step-by-step explanation:
3x+4=-5x-3+15
First combine like terms:
3x+4=-5x+12
Get x on one side:
3x+4=-5x+12
-3x -3x
4=-8x+12
Next get x by itself:
4=8x+12
-12 -12
-8=8x
Now divide one more time to get x by itself since 8x is 8 times x and we must do the opposite (÷).
-8/8=8x/8
-1=x ---> x=1
Answer:
- <u><em>x-int: (2, 0)</em></u>
- <u><em>y-int: (0, -5)</em></u>
To find the x-intercept, substitute in 0 for y.
To find the y-intercept, substitute in 0 for x.
