Answer:

[-8 1]

[ 0 4]

[ 6 3]

[ -3 -4]

Step-by-step explanation:

The given matrix is;

[-1 2]

[ 0 4]

[ 6 3]

[ -3 -4]

From the image given;

Row 1 is; (-1, 2)

Therefore, 2R1 = 2(-1, 2) = (-2, 4)

Row 3(R3) is; (6, 3)

Thus;

2R1 - R3 = (-2, 4) - (6, 3) = (-8, 1)

The new matrix after the transformation is;

[-8 1]

[ 0 4]

[ 6 3]

[-3 -4]

Nonamiya [84]

Answer:

1/6

Step-by-step explanation:

the form you're using is slope-intercept. That is

y=mx+b

where y= y coordinate

m=slope

x= x coordinate

and b= y intercept

so, m in that equation is 1/6, so the slope is 1/6

Hope this helps!

0.5s + 1 = 7 + 4.5s<br><br> Show work, and answers please. This is for algebra 1.
ioda
0.5s + 1 = 7 + 4.5s   Subtract 4.5s from both sides
  -4s + 1 = 7              Subtract 1 from both sides
       -4s = 6              Divide both sides by -4
          s = -\frac{6}{4}   Simplify
          s = -\frac{3}{2}

A box in the shape of a rectangular prism has a width that is 5 inches greater than the height and a length that is 2 inches gre
aliina [53]

The volume of the rectangular prism can be express in standard polynomial as follows:

x³ + 12x² + 35x

<h3>How to find the volume of a rectangular prism?</h3>

volume of a rectangular prism = lwh

where

  • l = length
  • w = width
  • h = height

Therefore,

let

height = x

width = x + 5

length = x + 5 + 2 = x + 7

Therefore,

volume = x(x + 5)(x + 7)

volume = x(x² + 7x + 5x + 35)

volume = x(x² + 12x + 35)

volume = x³ + 12x² + 35x
