Sophie [7]

Answer:

4 × ( 9 + 2z)

Step-by-step explanation:

36 + 8z = 4 × (9) + 4 × (2z) ; so here 4 is a common factor

= 4 × ( 9 + 2z)

we can also write it like this

36 + 8z = 2 × ( 18 + 4z)

Karyn proofreads 15 pages in 2 hours for $40.

OLEGan [10]

Hi there.

Since she reads 15 pages in 2 hours, all we have to do to find out how much she reads in 1 hour is divide.

15/2 = 7.5

7.5 pages/hour

Same applies to the pay

40/2 = 20

$20/hour

Karyn proofreading rate is 7.5 pages per hour. Karyn receives on average $20 per hour.

Through point (0, 10) and PERPENDICULAR to the line through (-2, -9) and (-4, -17)?

inn [45]

Compute the slope of the line through (-2, -9) and (-4, -17):

$\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4$

Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes

$y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}$
