Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple
kipiarov [429]

34x + 14 = 30x + 22
X is the amount the multiple choice question is worth. Both girls had the same test score so both are equal. Isolate X and that will be the value.

34x -( 30x) + 14 = 22
4x = 22 - (14)
4x = 8
4x \div 4 = 8 \div 4
x = 2

Plug 2 back in for x in the original equation to check and both girls recieved a 82%

Explain why ???? ??
Oksana_A [137]
The answer is B.

A linear function is a first-order polynomial, which is of the form y = ax + b. It is called first-order because the power of x is 1.

A second-order polynomial is of the form y = ax^2 + b; which eliminates A. This is also known as a quadratic function.

C. can be simplified to y = 2/3 - 7/x, which probably has a name as well.

D. can be simplified to y - y = 3x/8 + 1/8, which is 0 = 3x + 1 or x = -1/3. Not a linear function
