Answers fast : y=3x−49x−3y=14 use the substitution method. a.) there is no solution. b.) the solution is (12, 14). c.) the solution is (14, 12). d.) there are an infinite number of solutions.

Option A. There is no solution.

Step-by-step explanation:

we have

------> equation A

------> equation B

substitute equation A in equation B

------> is not true

therefore

The system has no solution

Explanation

The slope of the line A  is equal to

Find the slope of the line B

------>

The slope of the line B is equal to

therefore

Line A and Line B are parallel lines, because the slope is the same

The system has no solution

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
