Answer:
-80 percent
Step-by-step explanation:
Y = 3x + 4
y = 3x + 7
3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.
or look at it this way..
y = 3x + 4
y = 3x + 7
both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution
M=3q because 93/31=3 so 3 minutes per question will allow you to find how many minutes it took him for any number of questions
3(2x+1)=15
6x+3=15
-3 -3
6x=12
divide each side by 6
x=2
