Answer:
Step-by-step explanation:
x²-x-30=0
x² - 6x + 5x - 30 = 0
(x² - 6x) + (5x - 30) = 0
x(x - 6) + 5(x - 6) = 0
(x + 5)(x - 6) = 0
x + 5 = 0 or x - 6 = 0
x = -5 or x = 6
3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.

Using the concept of function, it is found that:
- Graphs B, C, D and F are functions.
- Graphs A and E are not functions.
-----------------------------
- In a function, one value of the input can be related to only one value of the output.
- In a graph, it means that for <u>each value of x(horizontal axis), there can only be one respective value of y(vertical axis). </u>That is, if a vertical line is traced at a value of x, it can cross the function only once, that is, there cannot be points aligned vertically.
- In graphs B, C, D and F, it can be seen that <u>for each x value, there is only one respective y-value</u>, thus, they are functions.
- In graphs A and E, for <u>values of x,</u> such as x = 3 for both, there are <u>two respective values of y</u>, thus they are not functions.
