C + D + E = 180
C + 63 + 35 = 180
C + 98 = 180
C = 180 - 98
C = 82°
Answer:
Step-by-step explanation:
A is a quadratic. Quadratics are not linear. It contains an x^2 term.
B isn't really a true value for a solution to a linear equation because there are x's on both sides of the equation. They can be divided out leaving you with 12 = 17.
C is linear It has 1 solution The answer to C is 3.64
D is linear it has 1 solution The answer to D is 5/12
Both C and D have only 1 solution each. That is one of the characteristics of linear equations.
The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be
