Write a linear function that relates to y to x

Answer:

The answer is c, C=1.5w + 5

Step-by-step explanation:

Let's write a general equation first,

C = mw + b, where C represents the shipping cost, w is the weight, m and b are non-zero constants.

By using the set of data in the table, what we can do is to substitute the corresponding values into our general equation. [Use any 2 set of numbers]

11 = 4w + b --(1)

17 = 8w + b --(2)

Here we got 2 equations, 2 unknown, thus we can get

w = 3/2, b = 5

The answer is c, C=1.5w + 5

[Noted that if you already got the slope(the yellow words), you can simply substitute one set of numbers into C=1.5w + b to find the value of b]

Answer:

so you wold do I=t×r×A ok so I=6,500 t=5 r=4.3 and u have to find A so you wolf multiple 5×4.3=21.5 and than you wold divide 6500÷21.5=302.3255813953488×21.5= 6500 so A=302.3255813953488

The correct expression will be ( 3 + 9) = ( 87 ÷ h ) + 9. The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 3 / 5 = 17²/₅ ÷ h. The expression will be solved as below,

3 / 5 = 17²/₅ ÷ h

3/5 = 87 / 5 ÷ h

h = 87 / 3

h = 29

Check option C for the value of h = 29.

3 + 9 = ( 87 / h ) = 9

3 = 87 / h

h = 87 / 3 = 29

Hence. the correct option is C.

The proportion relation between the number of games and the price is given by the proportionality constant k = 4.5

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of games be represented as x

Let the cost for the total number of games be y

And , the values of x = { 2 , 5 , 7 }

Now , the values of y = { 9.00 , 22.50 , 31.50 }

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

On simplifying , we get

9 = k ( 2 )

Divide by 2 on both sides , we get

k = 4.5

And , 22.50 = k ( 5 )

Divide by 2 on both sides , we get

k = 4.5

Therefore , the proportionality constant is k = 4.5

Hence , the proportion is y = 4.5x

Answer:

8x units

Step-by-step explanation:

A rectangle has an area of 56x²y units². If the height of the rectangle is 7xy. What is the length of the rectangle.

The Area of a Rectangle is calculated with the formula

Length × Width ( Height)

Area = 56x²y square units

Height = 7xy units

Length =Area of the rectangle/Height of the rectangle

= 56x²y square units/7xy units

= 8x units

Answer:

−7/18

Step-by-step explanation:

Subtract 5/9  from both sides of the equation

We choose the coordinates (4,4), (4,10), and (8,4) as the vertices of right-angle triangle ABC We want to dilate triangle ABC by scale factor of 2 at the center (0,2)The image is shown below as triangle A'B'C' with coordinates (8.6), (8,18), and (18,6). Triangle ABC has a base of 4 units and a height of 6 units

Triangle A'B'C' has a base of 8 units and a height of 12 unitsApplying Pythagoras theorem to triangle ABC to find the hypotenuse

Now, we calculate the hypotenuse of the image

The hypotenuse of the image is twice the hypotenuse of triangle ABC which proof the two shapes are similar shape

Answer:

So the inequality for this is 12.5x + 35 ≥ 105

and the amount of visits they need to get to their goal is 6 visits

Step-by-step explanation:

you subtract the points they already have (35) from both sides and you'll get..

12.5x ≥ 70

then you divide 12.5 from both sides and you'll get 5.6, or 6 visits

Answer:

ninth year

Step-by-step explanation:

Given the general form of an exponential equation;

P = a(1 +r)^t

We can now write in this particular case;

y = 4 * 10^6(1 + 0.07)^t

The year in which y reaches 7 * 10^6 dollars is

7 * 10^6 =  4 * 10^6 (1 + 0.07)^t

7 * 10^6/4 * 10^6 = (1 + 0.07)^t

1.75 = (1 + 0.07)^t

ln(1.75)= ln(1 + 0.07)^t

ln(1.75) = t ln(1 + 0.07)

0.5596 = 0.06766t

t = 0.5596/0.06766

t = 8 years

So, in the ninth year;

y =  4 * 10^6 (1 + 0.07)^t

y = 4 * 10^6 (1 + 0.07)^9

y = 7.35 * 10^6

Hence, the player's earnings first exceed $7,000,000 in the ninth year.

Answer:

Okay so what you do is multiply 6*9*4.5 together and that'll give you 243 as the volume of the prism. I'm not sure what it is in decimal. I'm guessing 24.3

I'm so sorry if this is incorrect.

Have a great day! <3

Answer:

121.5 ft^2

Step-by-step explanation:

To find Volume of Triangular prism, find the area of the triangular shape first.

Step 1:     6 x 4.5 = 27(square)

Step 2:   27 x .5 = 13.5(triangle)

13.5 x 9(the width) = 121.5

Because volume is length x width x height.

The height and length is 6 x 4.5 in this problem.

Note :  I did "x.5 " because I needed to divide 27 by two to get a triangle. Since a triangle is half a square.  Dividing by 2 and multiplying by .5 are the same thing.

Example: 20 x .5 =10 or 20/2 =10
