Is this correct?

yes if y = 0

Step-by-step explanation:

Yes you are correct. Here are the steps incase you need to find the y

Step-by-step explanation:

x−2y=2;3x+y=6

Step: Solvex−2y=2for x:

x−2y+2y=2+2y(Add 2y to both sides)

x=2y+2

Step: Substitute2y+2forxin3x+y=6:

3x+y=6

3(2y+2)+y=6

7y+6=6(Simplify both sides of the equation)

7y+6+−6=6+−6(Add -6 to both sides)

7y=0 Divide by 7

y=0

Substitute0foryinx=2y+2:

x=2y+2

x=(2)(0)+2

x=2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
