Which of the following equations is quadratic? x(x2 + 1) = 0 5(4x + 2) = 3 (x + 3)(x + 4) = 5
ValentinkaMS [17]
An equation is quadratic if the highest power of the variable in it is 2.

1. \\
x(x^2+1)=0 \\
x^3+x=0 \\
\hbox{the highest power: 3} \\
\hbox{not quadratic} \\ \\
2. \\
5(4x+2)=3 \\
20x+10=3 \\
20x+7=0 \\
\hbox{the highest power: 1} \\
\hbox{not quadratic} \\ \\
3. \\
(x+3)(x+4)=5 \\
x^2+4x+3x+12=5 \\
x^2+7x+7=0 \\
\hbox{the highest power: 2} \\
\hbox{quadratic}

(x+3)(x+4)=5 is a quadratic equation.

Does the table of values below represent a proportional relationship?
ladessa [460]

Answer:

No

Step-by-step explanation:

The constant of proportionality is k = y/x. In this case, k is 5. When you multiply k which is 5 with the x value you should get the y value. You will see that 2 X 5  = 10, 3 X 5 = 15, and 5 X 5  = 25 but 4X 5 is not equal to 24. This means the ordered pair (4, 24) does not lie on the straight line that is formed where all the other ordered pairs (2,10), (3,15), and (5,25) lie.

For a proportional relationship in a table, the k is constant for all the ordered pair x and y values. All the ordered pairs in the table should also lie on the same straight line.

So the answer is no.
