If k3 – 9 = 12, what is the value of k? A. 1 B. 7 C. 9 D. 63

63

Step-by-step explanation:

The answer is 63 because k/3 =63

k/3-9=12

We move all terms to the left:

k/3-9-(12)=0

We add all the numbers together, and all the variables

k/3-21=0

We multiply all the terms by the denominator

k-21*3=0

We add all the numbers together, and all the variables

k-63=0

We move all terms containing k to the left, all other terms to the right

k=63

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
