A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The membe
Setler79 [48]

Answer:

Equation = 225 + 50y

Step-by-step explanation:

Given

Members = 75

Cost of Shirt = $3

Color = $50 on all shirts

Required

Determine an equation to represent the scenario

Represent the members with x

Such that:

x = 75

First, we need to determine the total cost of ordering x shirts

A shirt costs $3;

So,

x\ shirts = 3 * x

x\ shirts = 3 x

Next, we determine the total cost of colors

Represent each color with y

1\ color = \$50

y\ color = \$50 * y

y\ color = 50 y

The required equation is calculated as thus;

Equation = x\ shirts + y\ color

Equation = 3x + 50y

Substitute 75 for x

Equation = 3 * 75 + 50y

Equation = 225 + 50y

If h and k are constants and x^2+kx+7 is equivalent to (x+1)(x+h), what is the value of k?
pantera1 [17]
The answer is K=(xh+x+h-7)/x
First you multiply the (X+1)(X+H) and get x^2+XH+X+H

Then you set it equal to X^2+KX+7=X^2+XH+X+H

Both X^2 CANCELS then move the 7 over by subtracting it giving you

KX=XH+X+H-7
Then divide by x giving you K by itself the answer bein K=(XH+X-H-7)/X
