Answer:8.5

Step-by-step explanation:

Pythagorean Theorem

a^2 + b^2 = c^2

3^2 + 8^2 = c^2

9 + 64 = c^2

73 = c^2

C= Sqrt (73)

C = 8.5

$2.30 x 4 = $9.20

$25.50 - $9.20 = $16.30

$16.30 ÷ 3 = $5.43

What equation is represented by the equation on the graph ?

solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Since the ien passing through (2,0) and (0,2).

$y-0=\frac{2-0}{0-2}(x-2)$

$y=-1(x-2)$

$y=-x+2$

This equation is represented by option D, therefore the option D is correct.

Can you help with did pretty please I'm stuck help just a, c ,d thanks luv.

Answer:

a) The slope of the function is 3.

c) The equation is represented by $n(t) = 3\cdot t + 35$ .

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

$n(t) = m\cdot t + n_{o}$ (1)

Where:

$m$ - Slope, measured in number of pieces per minute.

$t$ - Time, measured in minutes.

$n_{o}$ - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

$n$ - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that $n(15\,min) = 80\,p$ and $n(45\,min) = 170\,p$ , then the following system of linear equations is formed:
