Slope=change in y/change in x (y2-y1/x2-x1)

Slope=-2-(-5)/3-0=3/3=1

answer: slope=1

Answer:

<h2>1</h2>

Step-by-step explanation:

The formula of a slope:

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

We have the points (3, -2) and (0, -5).

Substitute:

m=\dfrac{-5-(-2)}{0-3}=\dfrac{-5+2}{-3}=\dfrac{-3}{-3}=1

P+45267=87012 evaluate
Rainbow [258]
Answer:

p+45267=87012

We move all terms to the left:

p+45267-(87012)=0

We add all the numbers together, and all the variables

p-41745=0

We move all terms containing p to the left, all other terms to the right

p=41745

PLS HELP ME ASAP ON COMPLETING THE COMBINATION CHART, OR ENOUGH TO ANSWER QUESTION “D”
Kitty [74]
In the table and chart, we have let x represent numbers of Rock CDs and y represent numbers of Rap CDs.

a) The purple dots represent feasible solutions. Their coordinates are listed in the table (for coordinates on the lines) and as a list of points (for points between the lines).

b) The feasible region for total time in hours is shaded blue.

c) The feasible regiion for total cost is shaded red.

d) The overlap of the two regions is shaded purple. The combinations that are feasible are purple dots in that region.

e) The equations used are listed at the left side of the chart. The equations are labeled by color. (≤112 is the cost equation; ≥75 is the hours equation)

ea) The area that is feasible with respect to both constraints is doubly-shaded.

eba) Too much money is spent to the right of the red line.
ebb) Too few hours are used to the left of the blue line.

f) The line for the desired profit is parallel to the "hours" line, but has x-intercept 10 and y-intercept 6. All the points shown except the two on the lower line will give the desired profit.

g) The higher profit line goes through the points (3, 7) and (8, 4). Those two combinations and the points on or near the upper line above y=4 will meet the higher profit requirement.
