Answer:

slope = $\frac{5}{3}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, - 2) and (x₂, y₂ ) = (2, 3)

m = $\frac{3+2}{2+1}$ = $\frac{5}{3}$

Answer: 5 /3

Step-by-step explanation: 5 /3 is correct. Point S has coordinates (-1, -2) and point R has coordinates (2, 3). Use the slope formula.

There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)

There's no solution to this particular system because the two lines are parallel.

How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.

The line on the left passes through the points (-1, 0) and (0, -2), so it has slope

(-2 - 0)/(0 - (-1)) = -2/1 = -2

The line on the right passes through (0, 2) and (1, 0), so its slope is

(0 - 2)/(1 - 0) = -2/1 = -2

The slopes are equal, so the lines are parallel.

Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.

Answer:

Cube Root

Step-by-step explanation:

Because there is a 3 outside the symbol.

That means the equation is stating: y * y * y = x

Beth works 8 2/4 hours, drives 1 1/4 hours, cooks 3/4 hours, and sleeps 7 2/4 hour's each day. How many hours of free time does

Jobisdone [24]

--------------------------------------------------------------------
Total time spent on work, drive cook and sleep
--------------------------------------------------------------------

$8 \frac{2}{4} + 1 \frac{1}{4} + \frac{3}{4} + 7 \frac{2}{4}$

$= 16 \frac{8}{4}$

$= 18$

------------------------------------------------------------------
Calculate Free Time
------------------------------------------------------------------
24 - 18 = 6

------------------------------------------------------------------
Answer: 6 hours of free time
