A linear function contains the following points. What are the slope and y-intercept of this function?

Scrat [10]

Answer:

slope: -1

y-intercept: 6

Step-by-step explanation:

y-intercept is when x is 0 so it's 8 and the slope can be found using the slope formula (y2-y1)/(x2-x1)

(6-8)/(0 - (-2)) = -2/2 = -1

Answer:

The average height of poodles in your kennel is 25.19 inches.

Step-by-step explanation:

This is a weighed average problem.

To find the weighed average, we sum each value of the set multiplied by it's weight, and then we divide by the sum of the weights.

In this problem, we have that:

Average 20.5 inches has weight 28.

Average 32.1 inches has weight 19.

What is the average height of poodles in your kennel?

$A = \frac{32.1*19 + 20.5*28}{19+28} = \frac{1183.9}{47} = 25.19$

The average height of poodles in your kennel is 25.19 inches.

3) Find the area of JUST the wood portion of the frame. This is called a composite figure.

dlinn [17]

The length of given frame is 7 inches

The width of given frame is 5 inches

Assume the thickness of frame is 1 inches (as it is not clear in picture)

Area of square will be 7*5= 35 sq.inch.

Area of hollow surface 5*3= 15 sq.inch.

Area of frame = square area- hollow area= 35-15

Area of wooden portion of frame = 20 sq.inch.
