Which graph represents a linear function?
pshichka [43]

Answer:

y + 2x = 10 (third option)

Step-by-step explanation:

We can see that every time x increases by one, y increases by -2, meaning that the slope is -2.

We also know that the y-intercept is 10 because that is the value of y when x is equal to 0.

Now, we can create the equation using the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept).

y = -2x + 10

If you look at the third option, that equation is just a rearranged form of our equation (y + 2x = 10).

This means that the third option is correct.

apex if you put down 15% on a $9000 car and pay monthly payments of $189.40 for 48 months what is the total price of the car
defon

The total amount payable for the car if you put a down 15% on a $9000 car and payment of $189.40 for 48 months will be:

Amount=(15/100×9000)+(189.40×48)

=1350+9091.2

=10,441.2

The total amount of money paid for the car after a period of time will be $10,441.2

Final height of the rectangle picture of pharmacy area is 391 ft2.
ozzi

Answer:The height of the pharmacy area is 17 feet

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The pharmacy area is rectangular. The height of the pharmacy area becomes the width of the rectangle.

The area of the pharmacy area is given as 391 ft^2

The length of the pharmacy area is given 23 feet

Therefore

23 × h = 391

h = 391/23 = 17 feet

Find the volume V of the described solid S. The base of S is the triangular region with vertices (0, 0), (3, 0), and (0, 3). Cro
Reil [10]

Answer:

27/2

Step-by-step explanation:

Given

Vertices (0, 0), (3, 0), and (0, 3)

Since the base of the equilateral in the plane perpendicular to the x-axis goes from the x-axis to the line y = 3 - x.

So, the length of each side of the triangle is (3-x)

Calculating the area;

Area = ½bh

Where b = base = 3 - x

height is calculated as;

h² = (3-x)² + (½(3-x))² --- from Pythagoras

h² = 9 - 6x + x² + (3/2 - ½x)²

Let h² = 0

0 = 9 - 6x + x² + (9/4 - 6/4x + ¼x²)

0 = 9 + 9/4 - 6x - 6/4 + x² + ¼x²

0 = 45/4 - 30x/4 + 5x²/4

0. = 5x²/4 - 30x/4 + 45/4

0 = 5x² - 15x/4 - 15x/4 + 45/4

0 = 5x(x/4-¾) - 15(x/4 - ¾)

0 = (5x - 15)(x/4 - ¾)

5x = 15 or x/4 = 3/4

x = 3 or x = 3

So, h = 3

Area = ½bh

Area = ½ * (3-x) * 3

Area = ½(9-3x)

Volume= Integral of ½(9-3x) {3,0}

V = 9/2 - 3x/2 {3,0}

V = 9x/2 - 3x²/4 {3,0}

V = 9(3)/2 - 3(3)²/4

V = 27/2 - 27/4

V = 27/2
