pls tell me I am not the only person who sucks at math :|
*pls answer correctly tho. it'd be nice O_O....yes brainlest and ect.. are included*

Consider this equation and the steps taken to solve it.

–9(a – 5) = –18 (distribute)
–9a + 45 = –18 (subtract 45)
–9a = –63 (divide by –9)
a = 7


What steps might you take to verify the solution? Check all that apply.

A) Substitute 7 for a.
B) Pick any value for a and substitute.

C) Simplify the equation after substituting the value for a.

D) Verify that a = 7 is correct when the result is a true statement.

E) Verify that a = 7 is correct when the result is a false statement.

Abe has 150 t-shirts to sell before the playoffs begin. The table shows the linear relationship between the number of t-shirts remaining, y, and the number of days he has been selling, X. T-shirt Sales Number of Number of Days T-shirts Remaining х

Which function can be used to find y, the number of t-shirts remaining after x days?​

Answers

Answer:

Y= -12x + 150

Step-by-step explanation:

1. You do the change in y over the change in x to get the slope.

y1 - y2 / x1 - x2 and you get the slope of -12

2. Making a point-slope form equation

y-y1=m(x-x1)

y-138= -12(x-1)

3. Turning point-slope form equation to slope-intercept

y-138= -12(x-1)

distributive property

y-138=-12x+12

add 138 on both sides

y= -12x+150
