A quadratic equation is usually in the form:

where a, b and c are the coefficients of the expression and a ≠ 0.
If a = 0, the equation becomes a linear expression and is no longer quadratic.
Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.
Hope you understand it and see what I did.
Answer:
<h2>138°</h2><h2 />
Step-by-step explanation:
∡5 = 42°
find: ∡ 14
solution:
since ∡5 = ∡13 = 42°
∡14 = 180 - ∡13
= 180 - 42
= 138°
Answer:
The inequality is 12.5v + 70 ≥ 215
and the amount of visits they can make is 12 visits
Step-by-step explanation:
if you take away (subtract) 70 from both sides, you'll get
12.5v ≥ 145
and when you divide both sides by 12.5, you'll get 11.6, or 12
