Answer:
D
Step-by-step explanation:
A function of x means that there can only be one value of y per x value. Therefore, D does not match this because there are 4 values of y per x value (3).
Answer:
Step-by-step explanation:
x² + 7x + 10 = 0
x = [-7 ± √(7² - 4·1·10)]/(2·1) = [-7 ± √9[/2 = [-7 ± 3]/2 = -2, -5
Answer:
C. 2 to the 4'th power
Step-by-step explanation:
2x2x2x2 is 4 2's, the number of 2's indicates the power, so the answer would be 2 to the power of 4 because there are 4 2's

Given:
The given term is 3x.
To find:
The like terms.
Solution:
Like terms are the terms which contain same variable and degree.
In the given term 3x, the variable is x and its degree is 1.
The variable in 4y is y and, 8 and 0.257 are constant. So, 4y, 8, 0.257 and 3x are not like terms.
On 10 has variable x and degree 1. So, 3x and 10x are like terms.
Therefore, the correct option is B.
