We can check by subbing in the values.

7x + 2y = -7
(7,9).....x = 7 and y = 9
now we sub
7(7) + 2(9) = -7
49 + 18 = -7
67 = -7 (incorrect)....therefore, (7,9) is NOT a solution for this equation

stellarik [79]
1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls

The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls

x=12*48=576

So it's 576 hours.

The slope intercept form of the equation of a line that passes through point (-2, -13) is y = 5x - 3. What is the point slope fo
Alona [7]

Answer:

B. y+13=5(x+2)

Step-by-step explanation:

I personally do y=_+_(x-_) when solving these equations

Plug in -2 the x coordinate for (x- (-2) to be (x+3)

Plug in -13 for the y intercept.

5 from 5x is the slope.

Thus y=-13+5(x+3)

Then just move 13 to the other side

Find the least common multiple of the following polynomials: 5y^2-80 and y+4
algol [13]
5y^2 - 80 = 5(y^2-16) = 5(y - 4)(y + 4)

LCM of 5(y - 4)(y + 4) and (y + 4) is 5(y - 4)(y + 4)
