Your answer is 25. You do 40 times 5 divided by 8 or 8 times 5 is 40 and 5 times 5 is 25. Hope this helps
Most textbooks interpret standard form of a quadratic function to be as follows:
f(x) =

In the function f(x) =

, notice we do not have a value for "c". Just place a "0" in for the c and you have standard form.
the criteria for standard form:
1. All like terms are combined
2. Degree must drop from left to right
3. The leading coefficient cannot be equal to zero.
Answer:
Second option: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We know that a line goes through the points
and 
Since the line intersects the y-axis when
, then the y-intercept of this line is:

Substitute the y-intercept and coordinates of the point
into the equation
and solve for "m":

By definition, the slopes of parallel lines are equal, then the slope of the other line is:

Knowing that it passes through the point
, we can substitute values into the equation
and solve for "b":

Therefoe, the equation of this line is:

Answer:
21
Step-by-step explanation:
Do 225 divided by 15 and divide 15 by 5 which gives you 3
