Question

Can someone please help me solve this math problem? Thanks!

Answer 1

Using a system of equations, it is found that the value of “b” in ax^2 + bx + c would be of:

B. 6

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, when x = 0, y = 15, hence c = 15.

When x = -1, y = 10, hence:

a - b + 15 = 10

a - b = -5

a = b - 5.

Then, when x = 1, y = 22, hence:

a + b + 15 = 22

a + b = 7

b - 5 + b = 7

2b = 12

b = 6.

Hence option b is correct.
