13(y+3)=13y+39
mutiply the bracket by 13
(13)(y)= 13y
(13)(3)= 39
13y+39= 13y+39
move 13y to the right side
sign changes from +13y to -13y
13y-13y+39= 13y-13y+39
0+39= 0+39
39= 39
Answer:
all real numbers
Graph A, I just graph it trust me
Answer:
6+4*(5-3)
Step-by-step explanation:
Because of PEMDAS l, we first solve in the parantheses. So 5-3 would be 2, then we multiply 2 by 4 which would be 8 obviously. Then we do the final step, add 6 and 8 which would be 14. Cheers!
In this case y=-7. Hope this helps :)
i know there's a way to calculate that with just a pencil ,
but nobody ever uses it.
This is one of the few situations where I gladly refer you
to a calculator. There, you'll find that the angle is
(<em>26 degrees</em>) plus or minus any multiple of 180 degrees.
