37. Construct Arguments Luis and Raul are

Katarina [22]

Using the slope - intercept relation, the required equation which models the scenario and Raul's speed are ;

y = - 7.5x + 15
4 miles per hour

Time difference, Δt = 1.2 hours - 0.5 hours = 0.7 hours

Change in distance, Δd = 11.25 - 6 = 5.25 miles

Assuming a constant speed :

Speed = (Δd ÷ Δt) = (5.25 ÷ 0.7) = 7.5 mi/hr

Using the general form :

y = bx + c

At, x = 1.2 hours ;

Miles left, y = 6 miles

End point decreases by 7.5 mi/hr (-7.5 mi/hr)

Inputting the data into the equation :

6 = - 7.5(1.2) + c

6 = - 9 + c

c = 6 + 9 = 15 miles

The expression in slope intercept form becomes ;

y = -7.5x + 15

If Raul lives 5 miles closer to the beach ;

Time it will take Luis to get to the beach :

Time taken = (15 ÷ 7.5) = 2.5 hours

Distance Raul has to cover = 15 - 5 = 10 miles

To reach the beach after 2.5 hours ;

Speed required = (10 ÷ 2.5) = 4 mi/hr

Therefore, Raul has to ride at 4 miles per hour for the plan to work.

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

$(\frac{2^1(2)^3}{4}^2)\\\\= (\frac{\frac{2(2^3)}{2} }{4})^2 \\\\= (\frac{1(2^3)}{4}) ^2\\\\= ( \frac{(1)(8)}{4} )^2\\\\= (\frac{8}{4})^2\\ \\= 2^2\\= 4$

So the answer is : $= 4$

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go

ki77a [65]

Answer:

10 visits

Step-by-step explanation:

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.

Let the number of visits be represented as: x

For John

John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.

The equation = $30 + $5 × x

= 30 + 5x

For Caleb

Caleb decided to go to Club4Fitness, which just charges $8 per visit.

The Equation = $8 × x

= 8x

We equate both equations to each other

30 + 5x = 8x

Collect like terms

30 = 8x - 5x

30 = 3x

x = 30/3

x = 10

Therefore, John and Caleb would spent the same amount of money after 10 visits.
