Answer:

You don't have enough money for 2 downloads

Step-by-step explanation:

<u><em>The complete question is</em></u>

The price for digital downloads of music is represented by the linear function f(x) shown on the graph. The price for digital downloads of movies is represented by g(x) = 3x, where x is the number of movies downloaded and g(x) is the total cost in dollars. Graph of a line with equation f of x equals one half times x plus 2. The x-axis is labeled Number of Songs, and the y-axis is labeled Price in Dollars. You want to make 2 downloads, and you have $2.50. Determine the least expensive option.

You download 2 songs.

You download 2 movies.

You download 1 song and 1 movie.

You don't have enough money for 2 downloads.

we have

f(x)=\frac{1}{2}x+2 ---> price for digital downloads of music

g(x)=3x ---> price for digital downloads of movies

<u><em>Verify all the options</em></u>

case 1) You download 2 songs

Calculate f(2)

For x=2

f(2)=\frac{1}{2}(2)+2=\$3

This option is not possible because

$3>$2.50 (don't have enough money)

case 2) You download 2 movies.

Calculate g(2)

For x=2

g(2)=3(2)=\$6

This option is not possible because

$6>$2.50 (don't have enough money)

case 3) You download 1 song and 1 movie.

Calculate f(1) and g(1)

For x=1

f(1)=\frac{1}{2}(1)+2=\$2.5

g(1)=3(1)=\$3

so

f(1)+g(1)=\$2.5+\$3=\$5.5

This option is not possible because

$5.5>$2.50 (don't have enough money)

case 4) You don't have enough money for 2 downloads

The statement is true

You have only enough money for download 1 song

Answer:

x=

Step-by-step explanation:

1.first solve the hypotenuse of (12 squared+16 squared) = (Hy squared)

2.then find the square root of the Hypotenuse

{h}^{2}  +  {b}^{2}  =  {hy}^{2}

What is the slope OF THE GRAPH, not what is A slope, what is THE slope
PtichkaEL [24]

You can find the slope either by just looking at the line or using the slope formula.

#1: The slope formula is:

m=\frac{y_2-y_1}{x_2-x_1}       Find two points and plug it into the formula

I will use (0, 2) and (1, -1)

(0, 2) = (x₁, y₁)

(1, -1) = (x₂, y₂)

m = \frac{y_2-y_1}{x_2-x_1}

m = \frac{2-(-1)}{0-1}   [two negatives cancel each other out and become positive]

m=\frac{2+1}{-1} =\frac{3}{-1}

m = -3

#2: To find the slope without having to do the work, you use this:

m=\frac{rise}{run}

Rise is the number of units you go up(+) or down(-) from each point

Run is the number of units you go to the right from each point

If we start at a defined/obvious point, like (0, 2), find the next point and see how many units it goes up or down and to the right. The next point is (1, -1), so from each point, you go down 3 units and to the right 1 unit. So your slope is -3/1 or -3. You can make sure the slope is right by looking at another point.
