saul85 [17]
X = number of lessons, y = total cost

y = 15x + 20 <== ur equation

when total bill was 125...y = 125
125 = 15x + 20
125 - 20 = 15x
105 = 15x
105/15 = x
7 = x <=== if Bill took 7 lessons, it would cost 125 <==

PLEASE SOLVE FOR Y: <img src="https://tex.z-dn.net/?f=7y%2B4%3D3-2y" id="TexFormula1" title="7y+4=3-2y" alt="7y+4=3-2y" align="a
ehidna [41]

Answer:

y = \frac{-1}{9}

Step-by-step explanation:

7y + 4 = 3 - 2y

add 2y  to both sides

7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3

add -4 to both sides

9y + 4 -4 = 3 - 4 \\9y = -1

divide both sides by 9

\frac{9y}{9} = \frac{-1}{9} \\

y = \frac{-1}{9}

For the following problem state the objective function and the constraints. DO NOT solve:
Mama L [17]

Answer:

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit P can be expressed as:

P=3S+5H

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

Step-by-step explanation:

We have an objective function that, in this case, we want ot maximize.

This function is the Profit (P).

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit can be expressed as:

P=3S+5H

We have 3 restrictions, plus the condition that both S and H are positive.

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0
