I do believe it would be x=30
0.3333333333... = 1/3
You can just say 0.3 repeating to say 0.33333...
Answer:
no
Step-by-step explanation:
to know if it is a function or not look at the x coordinate if any of the x coordinates repeat then its not a function but of any of the x coordinates don't repeat than it is a function
Answer:
13x^2-4
Step-by-step explanation:
(5x^2-3)+(8x^2-1)=
5x^2+8x^2-3-1=
13x^2-4
Answer:
x=8 and y=21
Step-by-step explanation:
12x-28=7x+12 (the 2 angles are equivalent)
12x-7x=12+28
5x=40
x=8
9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))
9y-77+12*8-28=180
9y=180+28+77-96
9y=189
y=21
