You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.
3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
Ur equation would be y=3/4x-7
Answer:
Step-by-step explanation:
We have to use absolute value notation to express the given statement.
Absolute value function:
- It is a function that contains absolute value symbol.

is used to express the distance between two points a and b on a number line.
We want to write a absolute value function for all numbers x whose distance from 6 is no more than 7.5 units.
Thus, we can write:

This can be interpreted as the absolute value of difference between x and 6(both in positive sense and negative sense) is less than equal to 7.5 that is not more than 7.5 units.
slope: 4/5 is a positive slope
- positive slopes rises from left to right
- positive slopes falls from right to left
- neither horizontal or vertical.
The picture below shows some examples of <u>equation with positive slope</u>.
