Could someone explain how to do this, I have no idea how...

Answer:

2.25

Step-by-step explanation:

Given the cost model:

C(l) = l3 – l2 + l + 2.5

l = Length fo package

The length of a package that cost $11.00

11 = l³ - l² + l + 2.5

From the table given :

Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50

Taking l as 2.20

2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508

Taking a slightly higher value :

Put l = 2.25

2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078

Ww can conclude that the length of mail would be 2.25

48[tex]x^{7}[/tex]y

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases , then

A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )

   = 2[tex]x^{5}[/tex] × 24x²y

   = 48[tex]x^{7}[/tex]y

The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

A trapezium is a quadrilateral with four sides where two sides are parallel to each other.

We have,

Trapezium.

Height = 4[tex]x^5[/tex]

Parallel sides are 15x²y and 9x²y.

The area of the trapezium.

= 1/2 x h x ( sum of the parallel sides )

Now,

Area of the trapezium.

= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)

= 2[tex]x^5[/tex] x (15x²y + 9x²y)

= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]

Thus,

The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

[tex]\boxed{\textsf{ The required graph of y = 4x will be a straight line passing through the origin . }}[/tex]

Step-by-step explanation:

Here we need to plot the graph for the function given to us . The function is ,

[tex]\sf \implies f(x)= 4x [/tex]

In order to plot a graph let us assume that ,

[tex]\sf\implies y = f(x) [/tex]

Hence we now get , that ,

[tex]\sf\implies y = 4x [/tex]

Now let's find out some values of x and y taking which we will plot the graph .

• So , firstly let , x = 0 then y will be equal to 4*0 = 0 . Hence we got one coordinates as (0,0) .

• Secondly let x = 1 , then y will be equal to 4*1 = 4 . Hence we get the third coordinate as (4,0) .

• Thirdly let us take that x = 0.5 then y will be equal to 4*0.5 = 2 . Hence we got the third coordinate as ( 0.5 , 2 )

• Fourthly let x = -0.5 then y will be equal to 4*-0.5 = -2 . Hence the fourth coordinate will be (-0.5 , -2)

Now when we plot it's graph taking suitable scale then it will look something like that as shown in attachment .

For the graph of y = 4x kindly refer to the attachment :) .

A 2-column table with 4 rows. Column 1 is labeled Store with entries A, B, C, D. Column 2 is labeled Advertised Bread Prices with entries 3 loaves for 5 dollars and 94 cents, 4 loaves for 7 dollars and 80 cents, 5 loaves for 10 dollars and 5 cents, 6 loaves for 12 dollars and 12 cents.

Camillo is making gourmet peanut butter and jelly sandwiches for a food challenge.

PLS HELP ASAP!!What is the unit price of a loaf of bread at each store?

Store A:

Store B:

Store C:

Store D:

Solution:

The unit price of an item is the price for a single unit of measure of that item. It is measured in price / unit measure.

unit price of a loaf of bread at each store = cost of the loaf of bread / number of loaves

For store A, unit price = $5.94 / 3 loaves = $1.98 per loaf

For store B, unit price = $7.80 / 4 loaves = $1.95 per loaf

For store C, unit price = $10.50 / 5 loaves = $2.10 per loaf

For store D, unit price = $12.12 / 6 loaves = $2.02 per loaf

yup the person above me is right but for C its $2.01 :>

2(12x + 6)

-6(-4x - 2)

12(1 + 2x)

The expressions that are equivalent to 24x + 12 are:

2(12x + 6)

-6(-4x - 2)

12(1 + 2x)

Let's go through each expression and simplify them to determine if they are equivalent to 24x + 12.

2(12x + 6):

We can use the distributive property to simplify this expression:

2 * 12x + 2 * 6 = 24x + 12

This expression is equivalent to 24x + 12.

–6(–4x – 2):

Again, using the distributive property, we simplify:

–6 * –4x + –6 * –2 = 24x + 12

This expression is equivalent to 24x + 12.

–3(8x – 4):

Once again, applying the distributive property:

–3 * 8x + –3 * –4 = –24x + 12

This expression is not equivalent to 24x + 12.

12(1 + 2x):

Using the distributive property:

12 * 1 + 12 * 2x = 12 + 24x = 24x + 12

This expression is equivalent to 24x + 12.

–4(–6 – 3x):

Applying the distributive property:

–4 * –6 + –4 * –3x = 24 + 12x = 12x + 24

This expression is not equivalent to 24x + 12.

Answer:

This is true look at picture for clarification

Answer:

True

Step-by-step explanation:

To see if the points all lie on the line y = 4/3x + 5, substitute their x and y values into the equation, solve, and see if the equation is true.

1) First, substitute the x and y values of (6,13) for the x and y in the equation and solve:

[tex]13 = \frac{4}{3} (6) + 5 \\13 = \frac{24}{3} +\frac{15}{3} \\13 = \frac{39}{3}\\13 = 13[/tex]

The result is a true equation. Thus, (6,13) is on the line.

2) Do the same with the point (21,33):

[tex]33 = \frac{4}{3} (21) + 5 \\33 = \frac{84}{3} +\frac{15}{3} \\33 = \frac{99}{3} \\33 = 33[/tex]

The result is a true equation. Thus, (21,33) is on the line.

3) Finally, do the same with (99, 137):

[tex]137 = \frac{4}{3} (99) + 5\\137 = \frac{396}{3}+\frac{15}{3} \\137 = \frac{411}{3} \\137 = 137[/tex]

The result is a true equation. Thus, (99, 137).

All three points are on the line, thus the statement is true.
