ANTONII [103]3 years ago

Answer:

  • - 10

Step-by-step explanation:

<u>Use two ordered pairs from the table to find the slope  of f(x):</u>

  • (-4, - 9) and (6, 6)
  • m = (6 - (-9)) / (6 - (-4)) = 15/10 = 1.5

<u>Find the equation of f(x) using point-slope form:</u>

  • y - y₁ = m(x - x₁)
  • y - (- 9) = 1.5(x - (-4))
  • y + 9 = 1.5(x + 4)

<u>The y-intercept is the value of y when x = 0:</u>

  • y + 9 = 1.5*4
  • y + 9 = 6
  • y = - 3

<u>Use two points on the graph and find the slope of g(x):</u>

  • (0, 4) and (1, - 3)
  • m = (- 3 - 4) / 1 = - 7

<u>Find the required sum:</u>

  • - 3 + (- 7) = - 10

Allushta [10]

Answer:

<h2>  $24</h2>

Step-by-step explanation:

The question is not complete, here is the complete question

"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>

<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24

PLEASE HELP WITH PART B!!<br><br> can you also explain y and x, I dont understand part B &gt;
Doss [256]

A. I would suggest including <em>all</em> units in your answer. Both answers are correct but the unit is also important.

average rate of change:

($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year

initial value:

$350

B. Take 2010 to be year 0. Then for year <em>x</em> = 0, the fee is <em>y</em> = $350.

If the fee increases at a rate of $100 per year, this means that when <em>x</em> = 1, <em>y</em> = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is

(450 - 350) / (1 - 0) = 100/1 = 100

which is the same as the average rate of change.

Using the point-slope formula for a line, the equation you want is then

<em>y</em> - 350 = 100 (<em>x</em> - 0)

<em>y</em> - 350 = 100<em>x</em>

<em>y</em> = 100<em>x</em> + 350
