−3x+3y=9
2x−7y=−14
What is the answer

x=-7/5 and y=8/5

Step-by-step explanation:

you can use direct substitution by solving the first equation for x

x=y-3

2(y-3)=-14

and you solve that for y

y=8/5

then you substitute that for the first equation

x=-3+8/5

x=-7/5

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
