M = - 10 + 9 / 2 + 5
m = - 1 / 3
answer:
21 + 3x (you would not put the x again since it is already given)
step-by-step explanation:
- we have to distribute 3 to the expression in the parenthesis
3 (7 + x)
= 21 + 3x
- this will be the expression once we distribute
Answer:
The 45% off discount saves an additional $10 compared to the 15% discount for a total of $15 off regular price.
Step-by-step explanation:
We can find the original price of the game through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $. Since 15% of 100% is the same ratio as $5 to the unknown original $ price, I write:

I can now cross-multiply by multiplying numerator and denominator from each ratio.

I now solve for y by dividing by 15.

The original price was $33.34.
Now, we can find the amount if 45% off and then then compare the two discounts. To find the percent off I can multiply by 0.45(33.34)=15. The 45% off discount saves an additional $10 compared to the 15% discount.
The equation of the line in slope intercept form is y = 7x - 2
<h3>How to find the equation of a line?</h3>
The equation of the line can be solved with the following equation.
y = mx + b
where
Therefore,
m = -2 - 5 / 0 - 1 = -7 / -1
m = 7
Hence, using (1, 5)
y = 7x + b
5 = 7(1) + b
5 - 7 = b
b = -2
Therefore,
y = 7x - 2
Hence, the equation of the line in slope intercept form is y = 7x - 2
