Make an inequality representing both constraints.
0.5x+y<20
x+y≥24

 Let x represent the number of magnets and y represent the number of key chains.

She must purchase at least 24 gifts but has to spend less than $20.


x + y >= 24

0.5x + y < 20


An appropriate solution is x=20 and y=5.  They satisfy both inequalities:


x + y = 25 so it is more than 24.

0.5x + y = 15 so it is less than 20.

A rectangular box with an open top has a length of x feet, a width of y feet, and a height of z feet. It costs $4.30 per square
almond37 [142]

Answer:

C=$(4.30xy+5.40(xz+yz))

Step-by-step explanation:

Surface Area of a Cuboid=2(LW+LH+HW)

Since the top is open

Surface Area = LW+2(LH+HW)

If Length = x feet,

Width =y feet

Height = z feet

Surface Area = xy+2(xz+yz)

Area of the base=xy

If it costs $4.30 per square foot to build the base

Cost of the base=Cost Per Square Foot X Area = $4.30xy

Area of the sides =2(xz+yz)

If it costs $2.70 per square foot to build the sides

Cost of the sides=Cost Per Square Foot X Area of the sides

= 2.70 X 2(xz+yz)

=5.40(xz+yz)

Cost of Constructing the Box = Cost of Constructing the Base + Cost of Constructing the Sides.

Therefore,

C=$(4.30xy+5.40(xz+yz))

What is the slope of the line that passes thru (7,2) and (9,6)?
Leya [2.2K]
Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:

y2-y1/x2-x1

Plug in the values.

6-2/9-7 =

4/2 =

2

Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.

Hope this helped!
