What is the correct value of x?

Step-by-step explanation:

1. First calculate for the gradient m

2. Calculate for the constant C by using any point (0,3) or (3,9)

3. Lastly, put the values found in the equation y = mx + c

1. m = Y2-Y1/X2-X1

=9-3/3-0=2

2. input one point together with m into the equation y=mx+c

3=2(0)+C

C=3

3. Therefore equation of linear relationship is

y = 2x + 3

Answer:

to figure this out you would need to know the circumference of the dime. then divide 41.8 by the circumference.

Step-by-step explanation:

if the circumference is aprox. 2.2 inches, then you would divide 41.8 by 2.2.

Answer:

C) On average, children grow about 9 inches every 2 years.

Step-by-step explanation:

Think about what the slope 9/2 means:

Slope is Change in Y / Change in X which is Change in Height / Change in Age, so 9 inches / 2 years means that on average, children grow about 9 inches every 2 years.

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles

Charges for one mile by Prestige car rentals = $0.07

Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]

Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]

Charges for one mile by Gateway Auto = $0.12

Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]

Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]

As per question statement, the charges are same:

[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

Answer:

10 years

Step-by-step explanation:

We are told that One year after you buy a tree, it is 10 feet tall. Thus, it's initial height after 1 year is 10 ft.

Now we are told that each year after you buy the tree, it grows 2 feet. This means that it's height after you bought it was; f(0) = 10 - 2 = 8ft

Thus,

f(1) = 8 + 2 = 10

f(2) = 8 + 2 + 2 = 12

f(3) = 8 + 2 + 2 + 2 = 14

The pattern here is;

f(x) = 8 + 2x

Where x is number of years

Thus, for it to reach a maximum height of 28 ft;

28 = 8 + 2x

Subtract 8 from both sides to give;

28 - 8 = 2x

2x = 20

x = 20/2

x = 10 years

That should be it.

Answer:

[tex]J' =(1, 3)[/tex]

[tex]K' = (4,4)[/tex]

[tex]L' = (6,0)[/tex]

[tex]M' = (-1,-3)[/tex]

Step-by-step explanation:

Given

[tex]J = (-6,6)[/tex]

[tex]K = (-3,7)[/tex]

[tex]L= (-1,3)[/tex]

[tex]M = (-8,0)[/tex]

Transformation: [tex](x,y) = (x+7,y-3)[/tex]

This means that, we add 7 to the x coordinate and subtract 3 from the y coordinate.

For J, we have:

[tex]J = (-6,6)[/tex]

[tex]J' =(-6 + 7, 6 - 3)[/tex]

[tex]J' =(1, 3)[/tex]

For K, we have:

[tex]K = (-3,7)[/tex]

[tex]K' = (-3+7,7-3)[/tex]

[tex]K' = (4,4)[/tex]

For L, we have:

[tex]L= (-1,3)[/tex]

[tex]L' = (-1 + 7,3-3)[/tex]

[tex]L' = (6,0)[/tex]

For M, we have:

[tex]M = (-8,0)[/tex]

[tex]M' = (-8+7,0-3)[/tex]

[tex]M' = (-1,-3)[/tex]

Answer:

7 1/2 dozen of cookies

Step-by-step explanation:

If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;

3 dozens cookies = 8 cups of butter

x cups of cookies = 20 cups of butter

Cross multiply

8*x = 3 * 20

8x = 60

x = 60/8

x = 7 4/8

x = 7 1/2

Hence you will need 7 1/2 dozen of cookies

La distancia real entre el hotel y el parque es 960 metros.

Step-by-step explanation:

Este es un caso de factor de escala, donde 5 centímetros en el mapa equivalen a 600 metros a escala real. Por tanto, la distancia entre el parque y el hotel en el mapa halla su equivalente mediante la siguiente regla de tres simple:

[tex]x = \frac{600\,m}{5\,cm}\times 8\,cm[/tex]

[tex]x = 960\,m[/tex]

La distancia real entre el hotel y el parque es 960 metros.

I hope this helped

Answer:

to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled

to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour

Step-by-step explanation:

Answer:

Step-by-step explanation:

LV to Colorado Springs = 595 miles

Colorado Springs to Mil=  929 miles

Total distance =                1524  miles

Average Speed = 1524 miles / 3 hours

Average Speed =  508  miles / hour

Answer:

24 minutes

Step-by-step explanation:

Given

Ashley = 12 minutes

Becky = 8 minutes

Required

Determine when they will be at the same point again

To do this, we simply determine the least common factor of both.

Ashley = 12, 24, 36, 48....

Becky = 8, 16, 24, 32........

From above, the least common factor is 24

Hence, both of them will be at the starting point in 24 minutes
