Answer:
2(x+1)²-3
Step-by-step explanation:
Using the vertex formula we can write the follwoing equation
y=a(x+1)²-3
We need to solve for a
we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3
15=9a-3
18=9a
a=2
Which means our final equation is
2(x+1)²-3
in standard form (just in case)
2x²+4x-1
Answer:
5 hours
Step-by-step explanation:
1. Find out how many dollars he earned on Saturday
3 x 6 = 18
He earned 18 dollars on Saturday.
2. Subtract 18 from 48 since that is from Saturday, not Sunday
48 - 18 = 30
3. Divide 30 by 6 to see how many hours he worked on Sunday
30/6 = 5
Answer:
approximately
1623.6
Step-by-step explanation:
16 1/2%=.165 which is approximately equal to 1/6, so we can just multiply the original number by 6.
Answer:
Your answer will be D. He knows that 30 × 16 is 5 then multiples 5 by 5 to get 25.
Answer:
Step-by-step explanation:
Subtract 7 From both sides
7-7 = 0, 16 - 7=9
That leaves
