Answer:

The subtraction property of equality

Option A is correct

Explanation:

The given equation is:

12 - x = 7x + 32

Subtract 12 from both sides

12 - 12 - x = 7x + 32 - 12

-x = 7x + 20 (Step 1)

From step 1 above, subtract 7x from both sides

-x - 7x = 7x - 7x + 20

-8x = 20 (Step 2)

Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality

Answer:

y = -3/2x + 3

Step-by-step explanation:

First, know that slope-intercept form is y = mx + b. Since our y-intercept is 3, we can plug that in for B, and since the slope goes down 3 and over to the right 2, it is -3/2. So, when everything's plugged in, we get y = -3/2x + 3.

I hope this helped! Please leave Brainliest if it did.

Five less than half the distance from Delaney’s home to the mall is more than 6 miles.
vovikov84 [41]

let x = the distance from Delany's house to the mall

 so half the distance would be 1/2x

then it is 5 miles less than that so you would subtract 5 to give you 1/2x-5

and that is more than 6 miles so you get 1/2x-5>6

Judah's family wants to ride the bumper boats at a water park. There are 4 children (c) and 2 adults 9 (a) in Judah's family. Th
zhannawk [14.2K]

Answer:

Yes, the boats are safe to ride.

Step-by-step explanation:

40 (4) + 12 (2) ≤ 500

160 + 24 ≤ 500

184  ≤ 500

184 is less than 500.

because I was not sure if you had 9 adults instead of 2, this is the answer:

40 (4) + 12 (9) ≤ 500

160 + 108 ≤ 500

268 ≤ 500

268 is less than 500

What is the reflection in the x-axis & what’s the reflection in line y=x?
marishachu [46]

Answer:

  a) (3, -4), (2, 4), (-5, -6)

  b) (4, 3), (-4, 2), (6, -5)

Step-by-step explanation:

a) Reflection in the x-axis negates the y-coordinate:

  (x, y) ⇒ (x, -y)

  (3, 4) ⇒ (3, -4)

  (2, -4) ⇒ (2, 4)

  (-5, 6) ⇒ (-5, -6)

__

b) Reflection in the line y=x swaps the x- and y-coordinates:

  (x, y) ⇒ (y, x)

  (3, 4) ⇒ (4, 3)

  (2, -4) ⇒ (-4, 2)

  (-5, 6) ⇒ (6, -5)
