So in matt's equation, he made a mistake in the a transision from line 2 to line 3
in line 2: -4(-2)2
in line 3: -4(4)
the mistake is that -2 times 2 is not equal +4 it is equal to -4
also from lines 5 to 6 he made a mistake in order of opperations (mulit division then addition and subtract)
line 5: -10+30/5
line 6: 20/5
so he first subtracted 10 then divided, he should have divided then subtracted
so the equation should have equaled
Karen used the correct (-) times (+) property and the order of operations
so Karen is correct and Matt is wrong.
I think the answer your after is 150.
Because she had the $12 dollars on their but she can only use it at a certain store
Answer:
139/100
Step-by-step explanation:
- Slope-Intercept form: y = mx + b, with m = slope and b = y-intercept
The easiest method to find the slope and y-intercept is to convert this standard form equation to slope-intercept form. Firstly, subtract 8x on both sides of the equation: 
Next, divide both sides by 12, and your slope-intercept form is: 
Now looking at this slope-intercept form, we can see that the <u>slope is -2/3 and the y-intercept is (0, 3/4).</u>
