Answer:

y = -1/5x + 6

Step-by-step explanation:

First rearrange x + 5y = 10 into y = mx + b format.

x + 5y = 10

5y = -x +10

y = -1/5x + 2

If a line is parallel to y = -1/5x + 2, it must have the same slope (-1/5).

Plug in for y = mx + b

x (x coordinate) = -5

y (y coordinate) = 7

m (slope) = -1/5

Solve for b.

7 = -5(-1/5) + b

7 = 1 + b

b = 6

y = -1/5x + 6 is parallel.

Answer:

Cheetah

Blue Wildebeest

Brown Hare

Elk

Step-by-step explanation:

Divide the distance by the time.

Blue Wildebeest: 33 1/3 divided by 2/3 = 50

Brown Hare: 8 divided by 1/6 = 48

Cheetah: 7 divided by 1/10 = 70

Elk: 18 divided by 2/5 = 45

Now you have to order the animals from who has the biggest number(top) to who has the smallest number (bottom).

Answer:

Elk

Brown Hare

Blue Wildebeast

Cheetah

Step-by-step explanation:

Divide the distance by time to make percent

Blue Wildebeast- 33 1/3 ÷ 2/3 = 50%

Brown Hare- 8 ÷ 1/6 = 48%

Cheetah- 7 ÷ 1/10 = 70%

Elk- 18 ÷ 2/5 = 45 %

Least to Greatest: 45%, 48%, 50%, 70%

Least (top) to Greatest (bottom): Elk, Brown Hare, Blue Wildebeast, Cheetah

Answer: The side of the house will the ladder reached by ladder = 16.52 feet

Step-by-step explanation:

House is standing vertical on the ground.

By placing ladder, it will become a right triangle with hypotenuse as ladder.

By Pythagoras theorem,

[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]

i.e.

[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]

Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

Answer:

EZ Excavation: y = 24.5x

Happy Hauling Service: y = 25x

Step-by-step explanation:

✔️Equation for EZ Excavation:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using any given pair of values from the table, say, (8, 196),

k = 196/8

k = 24.5

To write the equation, substitute k = 24.5 into y = kx

Thus:

y = 24.5x

✔️Equation for Happy Hauling Service:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using the coordinate of any point on the line, say (1, 25),

k = 25/1

k = 25

To write the equation, substitute k = 25 into y = kx

Thus:

y = 25x

Step-by-step explanation:

[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]

[tex]s = - \frac{28}{25} [/tex]

Answer: 195

Step-by-step explanation:

585/9=65

65*3=195

Answer:

The answer is 195 students.

Step-by-step explanation:

There are 2 solutions for this.

1st solution.

1. Start with the basics, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of students which is 3 to identify the total number of students that reported the 585 pictures.

3. 585/3 = 195, the total number of students.

2nd solution.

1. Start with the total again, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of pictures in each group total received pictures which is 9.

3. 585 divided by 9 = 65.

4. Take the number 65 which is the number of groups and multiply it by 3 the number of students in each group which will lead to the answer 195 again.

5. 195 is the number of students in total.

6. Extra: to even re-check your answers, multiply 195 by 3 and u will get 585, because each student did 3 reports.
