Answer:
I don't know the equation, but I will assume that 3 1/2 is the slope.
Step-by-step explanation:
For example, in the equation y = 10x - 9, the slope is 10.
Answer:
x = 9
Step-by-step explanation:
First, we want to isolate variable x on the left side of the equation. We can do this by adding 13 to both sides.
x - 13 + 13 = - 4 + 13
x = 9
Answer:
or
Step-by-step explanation:
The given quadratic equation is

Group the constant terms on the right hand side.


Divide through by 5.

Add the square of half the coefficient of x., which is
to both sides of the equation.

The left hand side is now a perfect square.

Take the square root of both sides;

Answer:
It's very simple. In 4 decimal digits there are 10,000 (0000 to 9999) possible values. The odds of any one of them coming up randomly is one in 10,000. A specific "4 digit number" would have 1/9000 chance, since there are 9000 4 digit numbers (1000-9999).
