T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
So Andrew is 4 years old
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
A way that I use to determine if something is a function or not is to ask whether or now it passes the “vertical line test”. In other words, does an x have two y’s? if we graphed these points, and proceeded to draw a vertical line through it, if it touches the function twice, then it is not a function. So I believe your answers would be A and C (In A, when x is 2, there are two y’s. Same goes with C, when x is 1, 4, 9 etc).
I hope this answer helps! :)
Answer:
i think it's this Bh(x) = (x + 1)(10x - 1)
Since it says when Added they are a negative and when multiplied they are positive, we know our two numbers are negative.
think of all multiples of 24
6 and 4
8 and 3
12 and 2
24 and 1
however, none of our choices here would be correct.
Answer:
see below
Step-by-step explanation:
m<Q: 360-68-71-124= 97 degrees
m<Y: 360-95-46-74=145 degrees
m<K: 360-49-89-72=150 degrees
m<R: 360-98-65-69=128 degrees
m<C: 360-77-123-86=74 degrees
m<X: 360-135-105-67=53 degrees
m<T: 360-66-114-92=88 degrees
m<F: 360-146-91-75=48 degrees
