Which tables represent constant functions?

Answer:

1st and last group represent similar figures.

Step-by-step explanation:

We have been given a graph. We are asked to find the similar figures.

We can see that triangles in the 1st group are similar triangles as the measure of their corresponding angles are equal.

We can see that rectangle in the last group are also similar as the sides of the yellow rectangle is 2 times the sides of smaller rectangle, therefore, last pair is also similar.

Therefore, 1st and last group represent similar figures.

Answer:

(1,-32):

3x − 4y = 9

3(1) - 4(-32) = 9

3 + 128 = 9

131 = 9

NO

(-1,3):

3x − 4y = 9

3(-1) - 4(3) = 9

-3 - 12 = 9

-15 = 9

NO

(-5, -6)

3x − 4y = 9

3(-5) - 4(-6) = 9

-15 + 24 = 9

9 = 9

YES

(23, -74)

3x − 4y = 9

3(23) - 4(-74) = 9

69 + 296 = 9

365 = 9

NO

By substituting the x and y values from the given ordered pairs into the equation, we find that the only ordered pair on the line represented by the equation 3x−4y=9 is (-5,-6).

The equation 3x−4y=9 represents a line on a coordinate plane, and ordered pairs (x, y) are points on this plane. To determine which given ordered pairs are on the line, we substitute each x and y value into the equation.

The only correct ordered pair on the line 3x−4y=9 is (-5,-6).

Answer:

p = 3

Step-by-step explanation:

distribute parenthesis on both sides of the equation

10p - 3p + 4 = 4p + 4 + 9 ( simplify both sides )

7p + 4 = 4p + 13 ( subtract 4p from both sides )

3p + 4 = 13 ( subtract 4 from both sides )

3p = 9 ( divide both sides by 3 )

p = 3

The equation of line CD in standard form is;

B: 5x - 3y = 30

Formula for slope of line between two coordinates is;

m = (y2 - y1)/(x2 - x1)

Thus, slope of line CD is;

m = (0 - (-5))/(6 - 3)

m = 5/3

c is y - intercept which is when x = 0.

Point D gives us the x-intercept because y is zero.

Thus;

0 = (5/3)(6) + c

c = -10

Thus, the equation of the line CD is;

y = (5/3)x - 10

Multiply through by 3 to get;

3y = 5x - 30

>> 5x - 3y = 30

Answer:

24 students

Step-by-step explanation:

If 60% equals 72, then 20% would be 1/3 of 72 which is 24.

Answer:

24 students selected milk

Step-by-step explanation:

Let x be the total number of students,

Since, 60% of students selected soda,

⇒ Number of students who selected soda = 60% of x = 0.6x

According to the question,

0.6x = 72

Divide both sides by 0.6,

⇒ x = 120

Now, 20% students selected milk

Hence, the number of student who selected milk = 20% of 120 = 0.20 × 120 = 24

The area of the section she wants to paint is 48 square feet.

In Euclidean Geometry, the area of a rectangle can be calculated by using this formula;

Area of rectangle  = length × width

Area of rectangle 1 = 4 × 9

Area of rectangle 1 = 36 square feet.

For the area of rectangle 2, we have;

Area of rectangle 2 = 4 × 3

Area of rectangle 2 = 12 square feet.

Now, we can find the area of the figure;

Area of figure = 36 + 12

Area of figure = 48 square feet.

Final answer:

The amount of yearly depreciation for the table saw is calculated by subtracting the depreciated value from the original cost and dividing by the number of years, resulting in an amount of $105 per year.

Explanation:

The question involves calculating yearly depreciation of an asset, which is a common topic in accounting and finance sections of high school mathematics or business studies.

To find the amount of yearly depreciation, we subtract the end value of the asset after depreciation from its original cost and then divide by the number of years over which the depreciation occurred. In this case, we have:

Original cost of the saw = $735
Depreciated value after 2 years = $525

Depreciation over 2 years = Original cost - Depreciated value
Depreciation over 2 years = $735 - $525 = $210

Yearly depreciation = Depreciation over 2 years ÷ Number of years
Yearly depreciation = $210 ÷ 2 = $105

Therefore, the yearly depreciation of the table saw is $105, which corresponds to option A.

Put the numbers in the data set in order from smallest to largest:

44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56

The smallest number is 44, the largest is 56, so the outside lines need to be above those numbers.

Both A and B have that.

Now find the median ( the average of the middle two numbers)

The middle two numbers from the list are 50 and 50 so the median would be (50 +50) /2 = 100/2 = 50

The middle line inside the rectangle needs to be above 50.

This makes the answer A.

Because in substitution method we first substitute the value of coefficient which has smallest coefficient and as a result the coefficient with greater coefficient is solved.

Final answer:

When solving a linear system by substitution, choose the variable that is already isolated in one of the equations. Substitute the value of that variable into the other equation.

Explanation:

When solving a linear system by substitution, it is important to decide which variable to solve for first. One strategy is to choose the variable that is already isolated in one of the equations. This makes it easier to substitute the value of that variable into the other equation.

For example, consider the system:

Equation 1: x + 2y = 5

Equation 2: 3x - y = 2

In this case, Equation 1 is already isolated for x, so it would be a good choice to solve for x first. By substituting the expression for x from Equation 1 into Equation 2, you can solve for the remaining variable y. Once you have the value of y, you can substitute it back into Equation 1 to find the value of x.

Recursive formula                  

f(n) = aₙ₋₁ * r

Step-by-step explanation:

Since, Nathan has two parents, four grandparents, and so on, it would form a Geometric Progression (GP) series for the number of Nathan's ancestors as below:-

2, 4, 8, 16, 32, ....

First term (a₁) = 2

Common Ratio (r) = [tex]\frac{a_{2} }{a_1}[/tex]

                             = [tex]\frac{4}{2}[/tex]

                             = 2

So,

Number of ancestors of Nathan if we go back n generations = a₁r⁽ⁿ⁻¹⁾

Plugging in the values of a₁ and r, we get

f(n) = 2*2⁽ⁿ⁻¹⁾                       [Explicit formula]

Now,

A geometric progression (GP) series is of the form,

a, ar, ar², ar³, ar⁴, ar⁵........

Step-by-step explanation:

Let x be the number of hours.

18x=90

Divide by 18 on each side

x=5

Final answer:

Corey can rent the canoe for 5 hours with his $90 by setting up and solving the linear equation 18x = 90.

Explanation:

To determine how many hours Corey can rent a canoe, given that he has $90 to spend and the rental cost is $18 per hour, we can set up a linear equation. We let x represent the number of hours Corey can rent the canoe for.

The equation is simply 18x = 90, where 18 represents the hourly rental rate of the canoe and 90 represents the total amount Corey has to spend.

To solve for x, we divide both sides of the equation by 18:

18x / 18 = 90 / 18

x = 5

So, Corey can rent the canoe for 5 hours with his $90.

Each friend paid $22.05 before the tip.

Keith and Michelle's dinner bill is a mathematics problem that can be solved by subtracting the tip from the total bill to find the cost of the meal alone and then dividing that amount by two to find out how much each friend has to pay without the tip.

First, we subtract the combined tip of $9.60 from the total cost of the meal, which was $53.70. This gives us the cost of the meal before the tip was added:

$53.70 - $9.60 = $44.10

Next, since Keith and Michelle spent an equal amount, we divide the cost of the meal by 2 to find out how much each friend pays:

$44.10 / 2 = $22.05

So, each friend paid $22.05 for the meal before adding in the tip.
