Answer:

Constraints:

0.50y+2.25x\geq 125\\x\geq 35\\y\geq 3x

Step-by-step explanation:

Let x represents the number of cards and y represents the number of cupcakes.

Carrie decides to sell cupcakes for $0.50 each.

Total amount earned from selling cupcakes =0.50y

Juanita decides to sell homemade cards for $2.25 each.

Total amount earned from selling cards =2.25x

As Carrie and Juanita need at least $125 to cover their start up costs,

0.50y+2.25x\geq 125

Juanita plans to make at least 35 cards.

x\geq 35

Carrie plans to sell cupcakes no less than 3 times the number of cards Juanita makes.

y\geq 3x

Constraints:

0.50y+2.25x\geq 125\\x\geq 35\\y\geq 3x

A flagpole casts a shadow that is 12 ft long. A 6-ft tall man casts a shadow
Vikentia [17]

Answer:

9ft

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are proportional.

Let the height of the flag pole be x feet.

\frac{x}{6}  =  \frac{12}{8}

We multiply both sides by 6 to get:

x =  \frac{12}{8}  \times 6

We reduce the fraction to get:

x =  \frac{3}{2}  \times 6

We now simplify

x = 3 \times 3

x = 9ft

What is the slope of the line through the points (-3,3) and (6,-8)
STatiana [176]

Answer:

\displaystyle \frac{-11}{9}

Step-by-step explanation:

       We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.

\displaystyle \frac{y_{2}-y_1 }{x_2-x_1}

\displaystyle \frac{-8-3}{6--3}

\displaystyle \frac{-8-3}{6+3}

\displaystyle \frac{-11}{9}
