Answer:

Yes, because when the values are substituted in, the equation becomes a true statement

Step-by-step explanation:

plug in the values for x and y and see if the equation makes sense

x=3

y=11

1/3(3)+11=12

1+11=12

12=12

Since the above equation is true, the point is a solution for the linear equation.

asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades :​ C, A,​ B, and A

Corresponding numbers of credit​ hours : 44​, 66​, 11​, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average​ (GPA):

\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}

=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}

=\frac{649}{13}=49.9230\approx 49.92

The grade point average of the student is 49.92.
