Part 1We are given

. This can be rewritten as

.
Therefore, a=1, b=-18, c=0.
Using the quadratic formula

The values of x are
Part 2Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a
quadratic function. Part 3.The first equation is

.
The second equation is

.
We have

Factoring, we have

Equating both factors to zero.

When the value of x is 6, the value of y is

When the value of x is -3, the value of y is

Therefore, the solutions are (6,38) or (-3,11)
Answer: 34+35
Step-by-step explanation: 35+33 bc that equals 69
x = y^2 + 10y + 22
Divide 10 by 2 to give 5 which becaoses the second term in the parentheses
x = (y + 5)^2 - 25 + 22
x = (y + 5)^2 - 3 Answer.
6.5 liters per 100 km travelled. 30% of 5 is 1.5, so adding this to the original amount results in 6.5
The answer is 360 miles since he can drive 60 miles per hour so just multiply 60x6 and your answer is 360
