Answer:
x=10.5
Step-by-step explanation:
5(x+3)=(6)(12)-[.5(6)(12-x)]
5x+15=72-36+3x
reduce
2x=21
x=10.5
check
5(10.5+3)=(6)(12)-[.5(6)(12-10.5)]
52.5+3=72-4.5
reduce
67.5=67.5
I agree with Josie, because it would be easier since the other three numbers are decimals. If you prefer fractions, then change the three decimals to mixed numbers.
Answer:
(1, -1), (1, -2), (2, -3), (2, -4)
NO
Step-by-step explanation:
✔️Each ordered pair is written as (input, output).
Thus, we would have the following:
(1, -1), (1, -2), (2, -3), (2, -4)
✔️This cannot be a function because every input value do not have exactly one output value related to it. A function should not have an input value related to more than one output value.
So, the answer is NO. It is not a function.
Answer:
My answer is D) y = 2(x - 2.5)^2 + 6
I hope it helps
Hi there!

We can begin by setting the two expressions equal to solve for t:
2t - 1 = 5t
Subtract 2t from both sides:
-1 = 3t
Divide both sides by 3:
t = -1/3
Plug in this value of t into x(t) and y(t):
x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3
y(-1/3) = 5(-1/3) = -5/3
Thus:
(-5/3, -5/3) are the corresponding coordinates.
