Answer:
Kennan will be from home approximately an hour and 48 minutes.
Step-by-step explanation:
We must know that total time () that Keenan will be from home is the sum of run (), hang out () and walk times (), measured in hours:
If Keenan runs and walks at constant speed, then equation above can be expanded:
Where:
, - Run and walk distances, measured in miles.
, - Run and walk speeds, measured in miles per hour.
Given that , , and , the total time is:
()
Kennan will be from home approximately an hour and 48 minutes.
The system of equations has infinitely many solutions
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x + 3y = 12 ------- eqn 1
y = x + 4 --------- eqn 2
We have to find the solution to the system of equations
We can use substitution method
Substitute eqn 2 in eqn 1
-3x + 3(x + 4) = 12
-3x + 3x + 12 = 12
-3x + 12 = -3x + 12
If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions
Thus the system of equations has infinitely many solutions
Answer:
x=3, solution is not extraneous
Step-by-step explanation:
we have
Solve for x
squared both sides
<u><em>Verify</em></u>
For x=3
-----> is true
therefore
x=3, solution is not extraneous
It is number 1 and number 2 because the equation is 242× 62 and Number 1 and 2 are just breaking it down
