9.75 * 1.2 = 11.7
24.5 * .8 = 19.6
11.7+19.6= 31.3 minutes
hope this helped :)
A = 1/2 (b x h)
A = 1/2(12.5 x 2.4)
A = 1/2(30)
A = 15
To find the correct answer, you have to simplify the equation.
Multiply -1/2 by everything in the parenthesis.
3/4x - 3x - 1/2 - 3x. Combine like terms.
-21/4x - 1/2. Turn -21/4x into a mixed number.
-5 1/4x - 1/2.
Your answer is D
Non linear because the degree of variable y is 1 and the degree of variable x is 2
