(–2,–7)

(0,–8)

(2,–9)

(4,–10)

(7,–11)

Answer:

Step-by-step explanation:

Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.

I'm bad at transitions so here's the math:

(y2-y1)/(x2-x1)

((-10)-(-9))/(4-2)

-1/2 ------> Thats "m".

SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE

The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.

Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.

y=mx+b

m=-1/2

b=-8

y=-1/2x+-8-----> y=-1/2x-8

Step-by-step explanation:

14/15 - 9/15 = 1/3

1/3 = 5/15

Answer:

Step-by-step explanation:

In this problem, both 7 and 14 can be divided by 1 and 7, meaning these are the factors. This tells us that 7 is the Greatest Common Factor, as 7 is greater than 1.

To factor the expression, we take 7 out of both numbers and put it outside the expression. To do this, we have to divide both numbers by 7. Doing this gives us \(7(\frac{7}{7} +\frac{14}{7} )\), which simplifies to \(7(1 + 2)\).

Answer:

63 minutes

Step-by-step explanation:

40+13+10 = 63

Answer:

-63

Step-by-step explanation:

The time before the play are negative and the tmes during the play are positive

assembly = 40 min

organising the puppets = 13 min

greeting children = 10 min

All the above are done before the actual start of the play so they will be recorded in negative minutes

Total time:

(-40) + (-13) + (-10)

= - 40 - 13 - 10

= -63

Step-by-step explanation:

3 x 2 is 6 and 6 + 3 = 9

Answer:

From left to right, -3/2, -4/5, -3/10, 1/2, 7/8, 4/3

Step-by-step explanation

So what we're trying to do here is to order the numbers from greatest to least.

Let's start off with the negative numbers.

-3/10, -4/5, -3/2.

Now what we want to do is give them all a common denominator to figure out which one is the least of that group.

-3/10,-8/10,-15/10.

Now on to the positive numbers.

1/2, 4/3, 7/8

Turn the denominator into 24.

12/24, 32/24, 21/24

Then put them all in order.

Answer:

-3/2, -4/5, -3/10, 1/2, 7/8, 4/3

Step-by-step explanation:

IS THW ANSWER

All you have to do is subtract the equations to get your solution.

1. -18 1/5 - (-2 3/5)  = -15 3/5

2. 49.40 - (-85.63) = 135. 03

3.  -52.89 - (-25.63) = -78.52

4. -96 2/9 - 24 4/9 =  -120 2/3

Note - when there is follow by a subtraction sign and then parentheses such as the examples of 1,2, and 3 you distribute that subtraction sign over. Which will result in positive number.

So, like - (-85.63), distribute the subtraction sign which will result into a positive 85.63.

Answer:

in the figure, each of the small squares has an area of 1. what is area of the shaded region?

45

Answer:

45

Step-by-step explanation:

Area of each shaded small square = 1

Number of shaded small squares = 45

Area of 45 shaded small squares

= 45 x 1

= 45

To determine the best prediction about the number of students who prefer ice cream, let's analyze the data provided in the table. According to the table, out of the 225 surveyed students:

Ice Cream: 81 students

Candy: 9 students

Cake: 72 students

Pie: 36 students

Cookies: 27 students

To estimate the number of students who prefer ice cream among the 5,000 total students, we can use the proportions:

Ice Cream proportion = (Number of Ice Cream preference) / (Total surveyed students)

Ice Cream proportion = 81 / 225

To estimate the number of students who prefer ice cream among the 5,000 total students, we can multiply the Ice Cream proportion by the total number of students:

Estimated number of Ice Cream preferences = Ice Cream proportion * Total students

Estimated number of Ice Cream preference = (81 / 225) * 5000

Calculating the estimated number of students who prefer ice cream:

Estimated number of Ice Cream preference = (0.36) * 5000

Estimated number of Ice Cream preferences ≈ 1800

Therefore, the best prediction about the scoops of ice cream the college will need is:

The college will have about 1,800 students who prefer ice cream.

So, option A is the correct answer.

Step-by-step explanation:

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

D

Step-by-step explanation:

Replace by the coordinates

3*3 -1>1

Answer:

D. (3,1)

Step-by-step explanation:

Plug the X and Y values into the expression y<3x-4

Substitute 3 for X and 1 for Y and simplify

y < 3x - 4

1 < 3(3) - 4

1< 9 - 4

1< 5

In this case 1 is less than 5, that is a correct statement, so your answer is C.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day
