TiliK225 [7]3 years ago
4 0

Answer:

The answer is

p =  \frac{ - 3}{1000} n + 97

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

m =  \frac{91 - 82}{2000 - 5000}  =  \frac{ - 3}{1000}  \\ to \: find \: the \: b \\ 91 =  \frac{ - 3}{1000}  \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \:  \\ p =  \frac{ - 3}{1000} n + 97

(a) Write down the gradient of the line with equation y = 7 - 4x The line L passes through the points with coordinates (- 3, 1)
lesya [120]

Note: Let us consider, we need to find the gradient of line L.

Given:

The given equation of a line is:

y=7-4x

The line L passes through the points with coordinates (- 3, 1) and (2, - 2).

To find:

The gradient of the given line and the gradient of line L.

Solution:

Slope intercept form of a line is:

y=mx+b                ...(i)

We have,

y=7-4x                   ...(ii)

On comparing (i) and (ii), we get

m=-4

Therefore, the gradient of the given line is -4.

The line L passes through the points with coordinates (- 3, 1) and (2, - 2). So, the gradient of line L is:

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{-2-1}{2-(-3)}

m=\dfrac{-3}{2+3}

m=\dfrac{-3}{5}

Therefore, the gradient of the line L is \dfrac{-3}{5}.

Schach [20]

Answer:

Ok so what you are suppose to do is find the area

Step-by-step explanation:

Which here is an explanation of how to find area (The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.)
