Two numbers multiply together to make 8, but add together to make - 6 What are the two numbers?​
Greeley [361]

Answer:

-4 and -2

Step-by-step explanation:

First find all the factors of 8, that would be 1 and 8, -1 and -8, 2 and 4, and -2 and -4.

Then, adding the groups of numbers you have should show you what would equal -6. So 1 + 8 = 9, -1 + (-8) = -9, same vice versa, 2 + 4 = 6, -2 + (-4) = -6. So -2 and -4 would be your two numbers.

Graph ​ 24x+25=−6y+7 ​.
MrRa [10]

Okay, So you have 24x+25=6y+7

Step 1: Pull out like factors : 24x + 18 + 6y  =   6 • (4x + y + 3)

Step 2: 4x+y+3  = 0

y-intercept = -3/1  = -3.00000

 x-intercept = -3/4  = -0.75000

Slope     = -8.000/2.000 = -4.000

And bam, you have a straight line
