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

The profit y (in dollars) for a business from selling x coats is represented by y=56x . Graph the equation.
Agata [3.3K]

Answer:

The graph of the equation is also attached.

From the graph, it is clear that at x = 0, the value of y = 0

Hence, the line passes through the origin with the y-intercept 0.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given that the profit y (in dollars) for a business from selling x coats is represented by the equation

y=56x

comparing with the slope-intercept form of the line equation

m = 56

<u>Determining the y-intercept</u>

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

substitute x = 0 in the equation

y = 56(0)

y = 0

Thus, the y-intercept b = 1

Thus,

The equation y = 5x has:

  • The slope m = 56
  • The y-intercept b = 1

The graph of the equation is also attached.

From the graph, it is clear that at x = 0, the value of y = 0

Hence, the line passes through the origin with the y-intercept 0.
