Answer:

see explanation

Step-by-step explanation:

A quadratic has a squared variable , this equation does not

The general form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

The equation here

x = 5 - 3x ( add 3x to both sides )

4x = 5 is not in quadratic form and is a linear equation, since the variable is x not x²

Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x  

2

+7x−8=0, b. (x+2)2=49(x+2)  

2

=49, c. 5x2−x−7=05x  

2

−x−7=0, d. x2+4x=−1x  

2

+4x=−1.

Can you help plz!!!!
Zolol [24]
Okay so the table represents B, in one hour of work, the person will make 18.25 (you get this by dividing 36.50 by two because that is how much they made in two hours, we need to know how much they make in one)
Therefore, the equation for A, which has to be less than B, would be either be Y=18x or Y=18.1x
