Answer:
D
Step-by-step explanation:
She spent $12 and *$ on two separate things, meaning she spent $20 on both.
So, 12 + 8 = 20.
If she started with 25, we subtract 20 from 25 to get how much she has left.
So, 25 - 20 = y.
Therefore, the answer is D.
Answer:
(1,–1), (4, –2), (9, –3)
Step-by-step explanation:
In the picture attached, the plot of the function f(x) = -√x is shown.
To verify which points lie on the line we compute the following table.
x √x f(x) = -√x
1 1 -1
4 2 -2
9 3 -3
Answer:
B and C
Step-by-step explanation:
They're congruent
multiply both sides by 2 to get
2A = (a+b)*h
divide both sides by h
to get 2A/h = a+b
subtract b from both sides to get a = 2A/h -b
