Average is the sum divideided by the number of numbers added together
so avarage of 3 number is 15 means
three numbers represented as x+y+z so
= 15
(x+y+z)/3=15
multiply both sides by 3 to clear fraction
x+y+z=45
45 is the sum of the 3 numbesr
double of that is
45 times 2=90
Answer:
the number that is greater than or less than
Answer:
The function with the largest value will be
Step-by-step explanation:
we know that
As x increases beyond 25 , that means
x> 25
so
Assume x=30
Substitute the value of x in each equation and find the value of the function, and then compare the results
case 1)
For x=30
case 2)
For x=30
case 3)
For x=30
case 4)
For x=30
therefore
The function with the largest value will be
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x=1+or- i square root of 22
