Using the unit rate, the graphs that best represent the amount they earn for different amount of time is: C.

The slope of a graph can be interpreted as the unit rate of the scenario that is being represented by the graph. For example, money earned in dollars per hour worked is the unit rate or slope of the graph given in this scenario.

The larger the unit rate value, the steeper the slope of the line of the graph.

Let Lin's unit rate be represented as x, therefore,

Lin's unit rate = x

Diego's unit rate = 2x

Jada's unit rate = 2(2x) = 4x

This shows that unit rate of Jada is the highest, and therefore, the graph that would represent how much Jada earns would be the steepest, followed by Diego's, and the least is Lin's.

Therefore, the all the graphs would be: C.

The machine will use 90 gallons of water to wash 24.5 pounds of laundry.

                     y ∝ x

Consequently, y = kx, where k is the proportionality constant.

Given:

The amount of water used by a washing machine varies directly with the weight of the load being washed.

Let's assume,

The amount of water used by a washing machine is y.

The weight of the load being washed is x.

According to the question,

y = 28 gallons

x = 7 pounds

Putting the values we get,

y = kx

28 = k × 7

k = 4

Now, we have to find y when x = 24.5

y = 4 × 24.5 = 98

Hence the machine will use 90 gallons of water to wash 24.5 pounds of laundry.

The new conditional statement that follows from the pair of true statement is If 4x + 5 = 13; then -5x = -10

The law of Syllogism states that if the following two statements are true:

Statement 1: If x , then y

Statement 2: If y , then z

Then we can derive a third true statement:

Statement 3: If x , then z

From the given;

Statement 1: If x , then y

If 4x + 5 = 13; then x = 2

Statement 2: If y , then z

If x = 2; then -5x = -10

Statement 3: If x , then z

If 4x + 5 = 13; then -5x = -10

Answer:

35+15 =50

50/2= 25 dollars

Answer:

1. C: y = 3x - 5

2. B: y = -3x - 9

Step-by-step explanation:

1.

y = 3x + 9; (2, 1) (parallel)

                 (x₁, y₁)

y - y₁ = m(x - x₁)

y - 1 = 3(x - 2)

y - 1 = 3x - 6

   +1         +1

-------------------

y = 3x - 5

----------------------------------------------------------------------------------------------------------

2.

y = (1/3)x - 6 ; (-3, 0) (perpendicular)

                     (x₁, y₁)

y - y₁ = m(x - x₁)

y - 0 = -3(x - (-3))

y - 0 = -3(x + 3)

y - 0 = -3x - 9

   +0          +0

----------------------

y = -3x - 9

Our range is 0 x  10, We could also graph this with x along with the x-axis and w along the y-axis then every minute 50x gallons are gone

We have 500 gallons of the water tank and it drains at the rate of 50 gallons per minute,

.Let's suppose after 5 minutes,

W = 500 - 50 * 5W = 500 - 250W = 250

After 5 minutes, 250 gallons are left in the water tank.

Here the lowest value is 0 so our maximum time is once the tank emptied, or when w is equal to 0.

0 = 500 - 50x

50x = 500X = 500/50X = 10

So, our range is 0 x  10

Answer:

18. m<EBC = 43°, m<CBD = 47°

19. m<EBC = 50°, m<ABC = 130°

Step-by-step explanation:

18. Find m<EBC and m<CBD

m<EBC = (5x + 8) and m<CBD = (6x + 5)

these two angles add up to a right angle, therefore their sum is 90°

5x + 8 + 6x + 5 = 90

11x + 13 = 90 , 11x = 77 , x = 7

m<EBC: 5(7) + 8 = 43

m<CBD: 6(7) + 5 = 47

19. Find m<EBC and m<ABC

m<EBC = (3x + 20) and m<ABC = (17x - 40)

these two angles are supplementary, meaning that they add up to 180°

3x + 20 + 17x - 40 = 180

20x - 20 = 180, 20x = 200, x = 10

m<EBC: 3(10) + 20 = 50

m<ABC: 17(10) - 40 = 130

Graphs are used mostly to show the relationship between two variables (usually x and y).

The graph of y = f(x) is attached

To get the values of x when f(x) = 0 , we  consider where the line of the graph crosses the x-axis.

The graph crosses the x-axis at:

x = 2

x = 8

This means that the values of x when f(x) = 0 are 2 and 8

Step-by-step explanation:

Hi there,

For us to answer the question we have to check if whether the end product on the both LHS and RHS are equal or not , so lets take each equation is whether both the sides are similar or not :

First eq :-

[tex]-2(x-5) = -2x + 5\\giving\\-2x+10\neq -2x+5[/tex]

Since it is not equal it is incorrect.

Second eq:-

[tex]-2(x+5) = -2x-5\\giving\\-2x-10\neq -2x-5[/tex]

Since it is not equal it is incorrect.

Third eq:-

[tex]-2(x+5) = -2x -10\\giving\\-2x-10=-2x-10\\[/tex]

The expected area of a circular sampling region is 531.56 m²

Given,

The radius of the circular sampling region = 13m

f(r) = [tex]\left \{ {\frac{3}{4} } \atop {0}} \right.[/tex] [1 - (13 - r)²] 12 ≤ r ≤ 14

We have to find the area of the circular sampling region = E (π r²)

E (π r²) = π E (r²)

Lets find E (r²)

E (r²) =₁₂ [tex]\int\limits^[/tex]¹⁴ r² f(r) dr

= ₁₂∫¹⁴ (3r²/4) (1 - (13 -r)²) dr

=  3/4 ₁₂∫¹⁴ r² (1 - 169 - r² + 26r) dr

= 3/4 ₁₂∫¹⁴ r² (26r³ - r⁴ - 168r²) dr

= 3/4 [ 26r⁴/4 - r⁵/5 - 168r³/3]₁₂¹⁴

= 3/4 [ (26 × 14⁴)/4 - 14⁵/5 - (168 × 14³)/3] - [ (26 × 12⁴)/4 - 12⁵/5 (168 × 12³)/3]

= 3/4 [ (26 × 38416)/4 - 537824/5 - (168 × 2744)/3] - [ (26 × 20736)/4 - 248832/5 - (168 × 1728)/3]

= 3/4 [ 249704 - 107564.8 - 153664] - [ 134784 - 49766.4 - 96768]

= 3/4 [-11524.8] - [-11750.4]

= 3/4 [225.6]

= 169.2

∴ E(r²) = 169.2

Now lets find the expected area of the circular sampling region:

Area = E(π r²) =  π E (r²)

Here, E(r²) = 169.2

So, area = π × 169.2 = 531.56 m²

By using division, if 89 members of the Taft school band spend a total of $4628 for tickets to Hammond's amusement park, The the cost of each amusement park ticket is $52

The total number of members of the Taft school = 89 members

The total cost for the ticket to Hammond's amusement park = $4628

The cost of each amusement park ticket = The total cost for the ticket to Hammond's amusement park ÷ The total number of members of the Taft school

Substitute the values in the equation

The cost of each amusement park ticket = 4628/89

= $52

Answer:

the vertical line is:

x = 5

The horizontal line is:

y = -9

Step-by-step explanation:

A vertical line has a fixed x-value, while a horizontal line has a fixed y-value.

Then we can write a vertical line as:

x = a

and a horizontal line as

y = b

Then, if we want a vertical line that passes through the point (5, -9), remember that the x-vale will be fixed, then we fix the x-value at the same x-value of the point, which we know that is 5, then the vertical line that passes through the point (5, -9) is:

x = 5

y = (3/2)x + 3

Step-by-step explanation:

Comment

The general equation is

y = mx + b

Finding m

The equation for the slope is

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

Givens

y2 = 3

y1 = 0

x2 = 0

x1 = - 2

m = (3 - 0)/(0 - -2)

m = 3 / 2

m = 3/2

Finding b

b is the y intercept which is (0,3)

x = 0

y = 3

3 = 0*3 + b

b = 3

So the equation is

y = (3/2) x + 3
