If five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
tensa zangetsu [6.8K]

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:

half a slice = 0.55 $

Given f(x) = x − 7 and g(x) = x2 . Find g(f(4)). g(f(4)) =
joja [24]
<h3><u>The value of g(f(4)) is -9.</u></h3>

f(x) = x - 7

g(x) = x^2

g(f(4))


f(4) = 4 - 7 = -3

g(-3) = -3^2 = -9

A square carpet of side length 9 feet is designed with one large shaded square and eight smaller, congruent shaded squares, as s
Pepsi [2]

Answer:

3\sqrt{3} + 72

Step-by-step explanation:

I attached an image to aid the understanding of the question.

Looking at the image, we see that the 8 shaded parts are congruent, as affirmed in the question as well. And we are told that T = 3, this implies that the area of the square with T as it's side is 9ft². Since all the 8 squares are congruenrt, it means each square has its area to be 9. Therefore, the total area of the 8 shaded squares will be:

9 \times 8 = 72ft^{2}

It remains the area of the shaded square with side S.

From the question, we have the following ratio:

\frac{9}{S} = \frac{S}{T}[\tex]But[tex]\frac{9}{S} = \frac{S}{3}[\tex]Multiplying through by 3S we have27 = S² and this gives:[tex]S = \sqrt{27} = 3\sqrt{3}

I did not add ± because length is always positive, so the case of negative is eliminated.

Now the areas of S is 3\sqrt{3}

Therefore, the total area of the shaded squares is

3\sqrt{3} + 72
