Alg Ch. 3 Closure

How many bricks were originally in the wall that Horace started tearing down?

What is Horace's equation? (let x=mins and y=bricks)

What is Martin's equation? (let x=mins and y=bricks)

When (in minutes) did the two walls have the same number of bricks?

6x(2x + y - 5)

(7x)(2xy)

(x - 2)(3 + y)

Write as the product equal to the sum. (If yours is not exactly like mine, it will be marked wrong, just know there are multiple correct ways to write the answer)

(x-1)(x+7)=(x+1)(x-3)

2x - 5(x + 4)= -2(x + 3)

|x+7|=11

|2x - 3|=23

Solve for y:

6x - 2y = 4

Solve for y:

6x + 3y = 4x - 2y + 8

(My answer has fractions not decimals)

What is the slope and y-intercepts for the equations above. (Yours will be marked wrong because you will not have the exact same wording as me.)
