The slope-intercept form is written as: y = mx+b

Rearranging -7x + 4y = -12,

4y = 7x - 12
y = (7/4)x -3

This would be how it must be written.

I hope I was able to help you with your question. Have a good day.

What is the volume of the pyramid
alexgriva [62]

Answer:

Option A - 32 cm³

Step-by-step explanation:

Volume of a pyramid is given by the formula :

V = \frac{lwh}{3}

Substituting values given gives us :

V = (4)(4)(6)/3

V = (16)(6)/3

V = 96/3

V = 32

Units will be cm³ as this is volume

Hope this helped and have a good day

He is paid a commission of 9 percent of his first $6,000 in sales during the month and 14 percent on all sales over $6,000. What
Agata [3.3K]

Answer:

  $1,956.80

Step-by-step explanation:

For amounts over $6000, the commission can be computed as ...

  0.14s -300 . . . . . . for sales (s) ≥ 6000

So, for $16,120 in sales, the commission is ...

  0.14×$16,120 -300 = $2,256.80 -300 = $1,956.80

__

The commission schedule suggests that for larger amounts, you divide the problem into two parts: calculate the commission on $6000, and separately calculate the commission on the amount over $6000.

  0.14(s -6000) + 0.09(6000)

  = 0.14s - 0.14·6000 +0.09·6000

  = 0.14s -300 . . . . the formula used above for s ≥ 6000
