Answer: Yes, at the 1st hour and 6th mile.

Step-by-step explanation:

If x= The number of hours and y= The number of miles, then the system of equations is \left \{ {{y=4x+2} \atop {y=6x}} \right.where Micah is the first equation and Luke is the second.

Solve by Substitution:

1) Solve y=4x+2 for y:

y=4x+2

2) Substitute 4x+2 for y in y=6x:

y=6x

4x+2=6x

3) Add -6x to both sides:

4x+2+-6x=6x+-6x

4) Simplify both sides of the equation:

-2x+2=0

5) Add -2 to both sides:

-2x+2+-2=0+-2

6) Simplify both sides of the equation:

-2x=-2

7) Divide both sides by -2:

\frac{-2x}{-2} =\frac{-2}{-2}

8) Simplify both sides of the equation:

x=1

9) Substitute 1 for x in y=4x+2:

y=4x+2

y=(4)(1)+2

10) Simplify both sides of the equation:

y=6

Therefore, They meet at the 1st hour at the 6th mile

Solve by elimination:

You can't solve the system of equations by elimination

Solve by graphing:

They cross at (1, 6), which supports my answer.

Help pleaseeeeeee, I need help
Arlecino [84]

Answer:

15, 60, and 61

Step-by-step explanation:

First we have to find the 3rd side length from 2 side length chosen. So let’s pick 8 meters and 11 meters, to find the third side length we use the Pythagorean theorem: c^2 = a^2 + b^2

c = 11^2 + 8^2 = 121 + 64 = 185 = 13.6

13.6 isn’t one of the answers so we can’t pick 11 & 8. Let’s try 11 & 15:

c = 15^2 + 11^2 = 225 + 121 = 346 = 18.6

18.6 isn’t one of the answers either. Let’s try 15 & 60:

c = 60^2 + 15^2 = 3600 + 225 = 3825 = 61.85

61.85 might be it but let’s try one more just in case:

c = 60^2 + 61^2 = 3600 + 3721 = 7321 = 85.6

Nope! That means 15, 60, and 61 are the answer. I hope this is correct!
