Answer:

- 18m² - 4m - 16

Step-by-step explanation:

2B - 2A

= 2(- m + 1 - 9m²) - 2(m + 9) ← distribute both parenthesis

= - 2m + 2 - 18m² - 2m - 18 ← collect like terms

= - 18m² - 4m - 16 ← in standard form

Find the slope and y-intercept of the line is parallel to y=-x-1 and passes through the point (5,-5)
Elanso [62]

Answer:

Step-by-step explanation:

y = -x - 1

the slope here is -1. A parallel line will have the same slope

y = mx + b

slope(m) = -1

(5,-5)....x = 5 and y = -5

now we sub....we are looking for b, the y int

-5 = -1(5) + b

-5 = -5 + b

-5 + 5 = b

0 = b

so ur equation is : y = -x + 0....or just y = -x

A gym membership charges $100 for a start up fee and $40 a month for
slamgirl [31]

The equation that represents the cost of membership is  $100 + $40c

The cost of 1 year membership is $580.

The number of months you have paid for is 9 months.

<h3>What is the equation that represents the cost of the gym membership?</h3>

The cost of gym membership is the sum of the fixed cost and the variable cost. The fixed cost is the start-up fee while the variable cost is the cost per month.

The equation that represents the cost of the gym membership is: c = $100 + $40m

Where m represents the number of months

The cost of 1 year membership =  $100 + $40(12)

$100 + $480 = $580

How many months would $460 cover = ($460 - $100) / 40 = 9 months
