1.) A linear function is two or more points on a graph that create a straight line.

2.) A non-linear function is two or more points on a graph that do not make a straight line.

3.) Area of a Triangle = 1/2 (Base x Height)

4.) Add all of the lengths of the sides together.

5.) pi = circumference/diameter, should give you approximately 3.14 which is pi.

6.) negative / negative = positive
negative / positive = negative
positive / negative = negative

7.) Multiply across and simplify.

8.) Length X Width

9.) You can count integers up and down the number line? That is my best answer for that question.

You will need 120 feet of fencing to put all the way around a rectangular garden. The length of the garden is 40 feet. What is the width?


A. 20 feet


B. 40 feet


C. 4,800 feet


D. 80 feet

Answers

Answer:

A. 20 ft

Step-by-step explanation:

(120/2)-40=20

Answer:

a) 20 feet

Step-by-step explanation:

We know it's a rectangle so lengths are the same and widths are the same

If length is 40

That would mean 120-2(40) = 80

We know 2 widths of a rectange so 40/2 is 20

Therefore 20 feet.

Your answer is (3, -4) .. to get that I plugged each set into the equation and solved to figure out which ordered pair makes this statement equivalent.. I got 13=13 after plugging in and solving so that makes it equivalent the other ordered pair makes an inequivalent outcome which was 9=13 ... I hope this helps

A basketball team needs to score more than 725 total points this season to set a new record. The team has already scored 165 points and it averages 70 points per game. How many more games does the team need to play if in order to set a new record? Assume the teams average number of points scored per game does not change.

Select the number line that includes the fewest number of games the team can play and still set the record.

Answers

Answer:

D.

Step-by-step explanation:

First, let's work out how many points they have to go. 725 - 165 = 560.

If they average 70 points per game, you'll need to divide 560 by 70.

560 / 70 = 8. Therefore, the team needs to play 8 or more games to get at least 725 points.

The answer
D because they need to play 8 games

Answer:

40 by 2.5 ?

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the equation of the line in slope-intercept form we to find the y-intercept(b) and the slope(m)

For the y-intercept(b) we can see that the line crosses/intersects the y-axis at 40 so the value of b equals 40 which means our y-intercept is 40

now all that is remaining is the value of m which we can find through the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

we take any two coordinates which lie on the line for example

(0 , 40) and (2 , 140) and plug it into our formula

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{140-40}{2-0}\\\\m=\frac{100}{2} \\\\m=50[/tex]

so the slope of the line is 50 which is m , so the equation of the line in slope-intercept form would be:

[tex]y=mx+b\\y=50x+40[/tex]

solve for x: -7 + x = 32

Answers

Answer:

X = 39

Step-by-step explanation:

Answer: 39

Work: So, we need to get x by itself, so we need to get -7 away from that side. So, we are going to add -7 to both sides, cancelling it on the side it's currently on. So, the equitation // answer is x = 39.

Check: Okay, let's add in 39 for x and solve the equitation. -7 + 39 = ? It equals 32. So, this is correct. I hope this helps, and Happy Holidays. :)
