How many posible solutions for x-3y=-3 and -2x+6y=12
Alexus [3.1K]

Answer:

there are no solutions

Step-by-step explanation:

x-3y=-3

-2x+6y=12

multiply the first equation by 2

2( x-3y)=-3*2

2x-6y = -6

add the 2 equations together


2x-6y = -6

-2x+6y=12

-------------------

0 = -6

this is not true

so there are no solutions

John is a quarterback. This year, he completed 350 passes, which is 70% of all the passes he's attempted this
diamong [38]

Answer:

455 passes

Step-by-step explanation:

If 350 is only 70% of his passes, take the remaining percentage which is 30% and multiply it to the known value of completed passes which is 350. So 350x.30= 105. Then just add 105 to 350 and you get the total number of passes. Hope this helped!

What is slope between the points (-5,7) and (4,-8)?
WINSTONCH [101]
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
