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

Rzqust [24]

Answer:

The equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order is Y = $225 + X × $50

Where;

Y = The total cost of the order

X = The number of colors on the shirts

Step-by-step explanation:

The number of T-shirts required by the members of the school choir = 75

The amount charged by the printing company per shirt = $3

The charge for each color to be printed on the shirts = $50

The number of T-shirts ordered = 75

The charge per shirt = $3

The number of colors on the shirts = X

The fee per color on the shirts = $50

The total cost of the order = Y

Therefore, we have;

The basic cost of printing the 75 shirts = The charge per shirt × The number of T-shirts ordered

∴ The basic cost of printing the 75 shirts = $3 × 75 = $225

The total fee of the added colors to the shirt = The number of colors on the shirts × The fee per color on the shirts

∴ The total fee of the added colors to the shirt = X × $50

The total cost of the order, Y = The basic cost of printing the 75 shirts + The total fee of the added colors to the shirt

∴ Y = $225 + X × $50

The equation is therefore;

Y = $225 + X × $50.

F(x) = x2+3x+2 x2+5x+4 Why is there no zero at x = –1?

dmitriy555 [2]

You could rewrite $F(x)$ as

$\dfrac{x^2+3x+2}{x^2+5x+4}=\dfrac{(x+1)(x+2)}{(x+1)(x+4)}$

and be tempted to cancel out the factors of $x+1$ . But this cancellation is only valid when $x\neq-1$ .

When $x=-1$ , you end up with the indeterminate form $\dfrac00$ , which is why $-1$ is not a zero.
