AveGali [126]
I think it’s a loyalty marking program. I think it’s that because I feel like it’s the only answer that really makes sense bc the customer is being loyal to the service in order to receive their “reward”

What are the x and y-intercepts of the line?
natta225 [31]

Answer:

B

Step-by-step explanation:

To find the y-intercept, plug in x=0 in the original equation. (You want to find what y is when x=0)

2x + 3y = -12

2(0) + 3y = -12 (Plug in x=0)

3y = -12 (2*0=0, so you can ignore that part)

y = -4 (Divide both sides by 3)

This narrows down our choices to either A or B.


To find the x-intercept, plug in y=0 into the original equation. (You want to find what x is when y=0)

2x + 3y = -12

2x + 3(0) = -12 (Plug in y=0)

2x = -12 (3*0=0, so you can ignore that part)

x = -6 (Divide both sides by 2)


If our x intercept is -6 and our y intercept is -4, that makes our answer B.

K = mv / 2 solve for m . HELP PLEASE HURRY!
Aleksandr-060686 [28]

9514 1404 393

Answer:

  m = 2k/v

Step-by-step explanation:

Identify the coefficient of m (v/2) and multiply by its inverse (2/v).

  (2/v)k = (2/v)m(v/2) . . . . multiply both sides of the equation by 2/v

  2k/v = m . . . simplify

  m = 2k/v

Which of the following are square roots of the number below? Check all that apply.
babunello [35]

We are to take the square root of 225. The only correct answer choices are plus or minus 15.


Thus, B is correct. C would be correct if you were to enclose the exponent (1/2) inside parentheses. E is correct, as it is one of two roots of 225.
