Y=a(x-h)^2+k
-5=a(1-0)^2+2
-5=a+2
-3=a
y=-3x^2+2
The answer would be prime
First, figure out what you do and don't know....
You do know that 3 times the sum of a number and 4 is 18 more than the number....you don't know the number so you make it the variable x
now take 3 times the sum of a number and 4 and make that an expression 3x+4 this expression is the same or equal to the sum of x and 18 x+18
3x+4=x+18
2x+4=18
2x=14
x=7
hope this helped :)
Answer:
$28
Step-by-step explanation:
Given that:
Value of Winning bid = $52
Winning bid 65% of the maximum bid.
To find:
How much more is the maximum bid from the winning bid ?
Solution:
We are given that the winning bid is 65% of the maximum bid.
Using this percentage value, we need to first find the value of maximum bid and then we need to subtract the value of winning bid from the maximum bid to find the answer.
Let the value of maximum bid = $
As per question statement:

Therefore, maximum bid = $80
Our answer is:
$80 - $52 = <em>$28</em>
0.8
you find how much he needed so:
24*0.3=7.2
than 8 he had , so whats left over
8-7.2=0.8
