Answer:

1

Step-by-step explanation:

Solve the equation for x:

3(x + 5) = -4x + 8

<em>Distribute.</em>

3x + 15 = -4x + 8

<em>Combine like terms.</em>

3x + 15 = -4x + 8

+4x         +4x

7x + 15 = 8

     -15   -15

7x = -7

<em>Divide both sides by 7.</em>

x = -1

The following equation has one solution, x = -1.

Aisha recorded the heights, in centimetres, of some girls.
sertanlavr [38]

Answer:

The median is marked at 161cm instead of 162cm.

The right part of the box (the upper quartile) is marked at 172cm, while the interquartile range is 17cm, so the upper quartile should be at 154cm + 17cm = 171cm.

Transform the equation 3x + y = 5 into slope-intercept form.
marin [14]

Answer: y=-3x+5

Step-by-step explanation:

Slope-intercept form is y=mx+b. So to make your equation into slope-intercept form, simply subtract 3x from both sides, which results in y=-3x+5

Answer:

  (13,-23)

Step-by-step explanation:

Comparing the image coordinates to the transformation rule, you see that ...

  (x -4, y +15) = (9, -8)

Adding (4, -15) to these coordinates, we get ...

  (x -4, y +15) +(4, -15) = (9, -8) +(4, -15)

  (x-4+4, y+15-15) = (9+4, -8-15)

  (x, y) = (13, -23) . . . . coordinates of D
