Answer: f(3) = 7
Step-by-step explanation:
f(3) = 5(3) - 8
15 - 8
f(3) = 7
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
So basically you are going to line up your equations (already done). Next, you will just add each term. So x + 3x = 4x, then 2y - 2y = 0 (we wouldn't put anything) then 7 - 3 = 4
So then we have all of our terms figured out and will have 4x = 4 then divide 4x by 4 to get x alone and then you will also divide the four that is by itself by four to equal one. So, your answer is x = 1. I hope that helps!
Answer:
2 = 65
1= 115
Step-by-step explanation:
angles 2 and 65° are equal
so input that in for 2
then subtract it by 180°
