Answer:

First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)

That is the first error of Alan.

Now, there is another error.

If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).

But we can not really divide by zero, so we should state that:

m can not be zero, if a line is horizontal, the perpendicular line must be vertical.

The functio p(x)= x(x-5)(x-2)(x+3) has four zeros. What is the smallest zero.
loris [4]

Answer:

x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root

Step-by-step explanation:

Solve for x:

x (x - 5) (x - 2) (x + 3) = 0

Split into four equations:

x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 5 to both sides:

x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 2 to both sides:

x = 5 or x = 2 or x = 0 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 5 or x = 2 or x = 0 or x = -3

Rus_ich [418]

Answer: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score are 720 which is considered a good payment point.

Explanation: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score is 720 which is considered a good payment point.

Explanation: Credit score is known as CIBIL. By this credit, score banks gauge the creditworthiness of a person. The data listed in our credit report CIBIL generate our credit score.

A person's credit history is submitted to CIBIL by banks and other financial institutions on a particular basis.

For example, if a person has a credit score of 600 then that person cannot be considered a good creditor. In this case, the bank doesn't lend him  .
