Answer:

Step-by-step explanation:

At y intercept, x = 0. So, y-intercept = b = 9

Slope intercept form : y = mx + b

y = mx + 9

To find the slope, take any point on the line.(2 , 5)

Substitute x and y values in the above equation and now we can find the value of m

5 = m*2 + 9

5 - 9 = 2m

-4 = 2m

-4/2 = m

m = -2

Equation of the line:

y = -2x + 9

The domain of a relation tells us the possible x-values.

The range of a relation tells us the possible y-values.

When we're given a set of data, we can find the domain or range by simply naming the x-values or y-values, respectively.

It is preferred that we order the values from least to greatest.

We are asked to find the range of the relation. This means that we need to name all the y-values of the given data:

2, 4, 5, 2, 9, -5

Notice how the y-values of 2 occurs twice. We only have to name it once:

2, 4, 5, 9, -5

Now, order the numbers from least to greatest:

-5, 2, 4, 5, 9

The range of this relation is {-5, 2, 4, 5, 9}.

Hey there!

40 - x^2 = 0

-x^2 + 40 = 0

SUBTRACT 40 to BOTH SIDES

-x^2 + 40 - 40 = 0 - 40

SIMPLIFY IT!
-x^2 = -40

DIVIDE -1 to BOTH SIDES

-x^2/-1 = -40/-1

SIMPLIFY IT!
x = ± 2√10

Therefore, your answer is:

x = 2√10 or x = x = -2√10

Answer:

Mostly likely it's True

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

The square of an even number is always even.

Examples:

8² = 64

64² = 4096

6² = 36

13040² = 170,041,600

The length of the ramp is  61 feet.

In order to determine the  length of the ramp, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where a = length

b = base

c = hypotenuse

√11² + 60²

√121 + 3600

√3721

= 61 feet

Answer:

72

Step-by-step explanation:

You can find ten percent of 180 pretty easily, it is 18 (divide by 10) then multiply by 4 to get 40%.

Answer:

72

Step-by-step explanation:

10% of 180 = 180 ÷ 10 = 18

⇒ 40% = 4 x 10% = 4 x 18 = 72

Or,

convert 40% into a decimal:

40% = 40/100 = 0.4

⇒ 40% of 180 = 0.4 x 180 = 72

The cost will be $164.49 if the first five CD's for a total cost of 5.00, and then will pay 15.99 for each Cd option (D) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Alan joined a CD's, and you club where he gets the first five CDs for a total cost of 5.00, and then will pay 15.99 for each Cd.

The linear equation is:

y = 15.99x + 5.00

Plug x = 10

y = 15.99(10) + 5.00

y = $164.49

Thus, the cost will be $164.49 if the first five CD's for a total cost of 5.00, and then will pay 15.99 for each Cd option (D) is correct.

Based on the calculations, the ratio 28:40 is proportional to the ratio 7:10.

Ratio can be defined as a mathematical expression that is typically used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

In this exercise, we would determine a ratio that is proportional to the given ratio by dividing it in simplest form as follows. Thus, we would divide both sides by 4:

[tex]28:40 = \frac{28}{4} :\frac{40}{4} =7:10[/tex]

Answers:

5) A.) 26 and 6) D.) 30

Step-by-step explanations:

Question 5)

For this question, we need to analyze the graph given and look at how many people scored 601 or above on the math portion. So, looking at the answers given we aren't going to have a smaller number of only 16 or 10, since they are both equal to or higher than 601. So, we need to add the amount of students that scored the 601 or higher amount.

16 + 10 = 26.

This answer matches up with the answer given of A).

Question 6)

For this question, it is similar except you don't add the numbers given. Instead, the question is asking for a specific amount given. So, looking at the answers given, yes 18 and 6 did score below 500, but the question asked "...scored 500 or below?" This is a specific question telling us about the 500 or below, which is in one column. As shown in the graph, 30 students scored this specific amount, which gives us our answer of D).

Answer: Below

Step-by-step explanation:

This is pretty simple. Since we know that it's a sum of two numbers, we can divide 68 by 2.

68/2 = 34

So we know that 34 + 34 is 68.
Now what we do is subtract 3 from one side and add 3 to the other 34. Note it is not 6 because subtracting and adding separates them by 2 units.

So, our large number is 37 and our small is 31.

Answer:

larger #=32

smaller #= 26

Step-by-step explanation:

We can solve this by using x for the larger number.

larger #= x

smaller #= x-6

x+x-6=58

2x-6=58

2x=64

x=32

The larger number is 32. To find the smaller # you simply substitute the variable x-6 which is now 32-6 which is 26.
