First subtract the constant to the other side to simplify it for now
y-5=-x^2+6x
Then pull out a common factor so the coefficient is x^2
y-5=-1(x^2-6x)
Next you take 1/2 of the b value (-6) and square it to find your c value
[1/2(-6)]^2=9
After that plug 9 into your equation as your c value
y-5=-1(x^2-6x+9)
Adding the C-value (9) causes the equations to become unbalanced so you need to balance them back out by minus 9 to the other side
y-14=-1(x^2-6x+9)
Now you want to simplify the equation on the right side.
y-14=-1(x-3)^2
Finally you want to add the constant back to the right side.
y=-1(x-3)^2+14 <——— vertex form
maximum=(3,14)
Answer:
<h3>(xy)/2 is the right answer.</h3>
60mins in 1 hour
80mi per 10min=xmi per 60min
ration and porportion
80mi/10min=xmi/60min
times both sides by 60min
480mi=xmi
answer is 480miles per hour
Hello,
we suppos the numbers are 1 and 2.
1+2=3
67-3=64
We must thus add 32 to each number
numbers are 1+32=33
and 2+32=34
(we don't need equation to solve that!)
Answer:
18.18%
Step-by-step explanation:
-Percent error is defined as the deviation as a percentage of the actual value.
#Given the actual sold units is 110 and the predicted is 90, the percent error can be calculated as:
Hence, the perecent error is 18.18%
