For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:

slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.

The equation of the line would be y = 0.5x + 9

Vesna [10]

Answer:

For a flag with 2 different colours, there are 8 possible colours for the first colour to be chosen from and 7 possible colours (excluding the first colour already chosen) for the second colour to be chosen from, given that colours are different. Hence there are a total of 8 x 7 = 56 possible flags to be created.

38.4;

Step-by-step explanation:

32.5% × ? = 12.48

? =

12.48 ÷ 32.5% =

12.48 ÷ (32.5 ÷ 100) =

(100 × 12.48) ÷ 32.5 =

A circular swimming pool has a radius of 28ft. There is a path all the way around the pool that's 4ft wide. A fence is going to
Natalka [10]

Answer:

Therefore 200.96 ft.of fencing are needed to go around the pool path.

Step-by-step explanation:

Given, a circular swimming pool has a radius of 28ft. There is a path all the way around the pool. The width of the path 4 ft.

The radius of the outside edge the pool path is

= Radius of the pool + The width of the path

= (28+4) ft

= 32 ft.

To find the length of fencing, we need to find the circumference of outside the pool path.

Here r= 32 ft

The circumference of outside edge of the pool path

=2\pi r

=(2\times 3.14 \times 32) ft

=200.96 ft.

Therefore 200.96 ft.of fencing are needed to go around the pool path.

Type the correct answer in each box. Use numerals instead of words.
Hatshy [7]

Answer:

(4,-3) and (-2,5)

Step-by-step explanation:


It was given that the points (-3,4) and (5,-2) are on the graph of the function f.


If g is the inverse function of f, then g will take the y-values as inputs and give the x-values as outputs.

Hence we will have the ordered pairs (4,-3) and (-2,5)

on g.


In other words, f and g are symmetric about the line y=x. This implies that when we reflect the points (-3,4) and (5,-2) in the line y=x we will obtain (4,-3) and (-2,5).


This point must lie on g.
