Help me on number problem 4 please
kakasveta [241]

Answer:

y = -1/4x + 3

Step-by-step explanation:

Because you are finding the perpendicular slope, you need to find the negative reciprocal of the original line, which would be -1/4. You then use point slope form to find the y-intercept with the slope and given point:

y - 5 = -1/4(x + 8). That equals to y = -1/4x + 3.

So the equation of this line is y = -1/4x + 3.

Let x = hours spent babysitting on Saturday. Choose the equation that
Ne4ueva [31]

The equation that can be used to represent the situation given that x is the number of hours spent babysitting is 4(x + 8) = 56

<h3>How to write and solve equation</h3>

  • Amount paid per hour for babysitting =$4
  • Total amount made = $56
  • Hours spent babysitting on Sunday = 8 hours

Total earned babysitting on Sunday = Hours spent babysitting on Sunday × Amount paid per hour

= 8 × 4

= $32

Number of hours he babysat on Saturday = $56 - (8 × 4) ÷ 4

= 56 - 32 ÷ 4

= 24 ÷ 4

= 6 hours

  • check all that applies

A. 8x+4 = 56

8x = 56 - 4

8x = 52

x = 52/8

x = 6.5

B. 4x+8 = 56

4x = 56 - 8

4x = 48

x = 48/4

x = 12

C. 8(x + 4) = 56

8x + 32 = 56

8x = 56 - 32

8x = 24

x = 24/8

x = 3

D. 4(x + 8) = 56

4x + 32 = 56

4x = 56 - 32

4x = 24

x = 24/4

x = 6
