What is the slope of the line? ​
Alexxx [7]

Answer:

Should be, (-3,5) (if rise over run aka y,x)

Step-by-step explanation:

When attempting to find a slope like this, you need to locate pretty points. Pretty points are any time the line meets an exact corner on the box. If you look at -3,1, you can see the line makes a pretty point there. Then, try to find the next one, which is at 2,-3. Once you found these pretty points, try to connect them by drawing a line towards each other THAT IS STRAIGHT until those intersect. Where they intersect is where the slope of the line is. In this case, when I drew the line, they met at <em>down three</em>, <em>over (right) 5.</em>

The Wellbuilt Company produces two types of wood chippers, economy and deluxe. The deluxe model requires 3 hours to assemble and
seropon [69]

Answer:

The maximum profit is reached with 4 deluxe units and 6 economy units.

Step-by-step explanation:

This is a linear programming problem.

We have to optimize a function (maximize profits). This function is given by:

P=98D+72E

being D: number of deluxe units, and E: number of economy units.

The restrictions are:

- Assembly hours: 3D+2E\leq24

- Paint hours: 0.5D+1E\leq8

Also, both quantities have to be positive:

D\geq 0\\\\E\geq0

We can solve graphically, but we can evaluate the points (D,E) where 2 or more restrictions are saturated (we know that one of this points we will have the maximum profit)

(8;0) \rightarrow  P=98*8+72*0= 784\\\\(0;8) \rightarrow P= 98*0+72*8=576\\\\(4;6) \rightarrow P=98*4+72*6=824

The maximum profit is reached with 4 deluxe units and 6 economy units.
