A Chess Team Is Ordering Customized T-shirts For A Competition. The Table Shows The Cost Of Ordering

Answers

Answer 1

Answer:

y=8x+36

Step-by-step explanation:

Use y=mx+b.  First find m, the slope.  

To do that, use y2-y1/x2-x1.  Use any two point combinations from the table.  You can use (6,84) and (12,132).  

Y2 would be 132 and Y1 would be 84, and X2 would be 12 while X1 is 6.  Just look at the pointss.  For example, Y2 is 132 because (12,132).  132 is in y's spot.  Same goes for x.

Now that we got y2, y1, x2, and x1, we can plug it into the formula and solve.

y2-y1/x2-x1= 132-84/12-6= 48/6= 8

This means the slope is 8.  Now, we need to find the y intercept.

Use y=mx+b again and use any pair of points.  I'm going to use (6,84).

y=mx+b.  Plug in the slope, which is 8.

y=8x+b

y=8x+b.  Plug in the y.  The y variable is 84 so plug that in.

84=8x+b.  Same for the x.  The x variable is 6 so plug that in as well.

84=8(6)+b.  Now simplify it.

84=48+b.  You want to isolate b to find the y intercept so move the 48 to the left side.  

It's now 84-48=b.  The 48 because negative because whenever you move a number to the other side, it switches its sign.

Solve.

84-48=b

36=b or b=36.  So the y intercept is 36.

We now have our slope and the y intercept.  

Slope: 8

Y intercept: 36

We can plug that into y=mx+b a final time.

y=8x+36

Answer 2

The equation of the linear model is y = 8x + 36

The standard form of a linear equation is given by:

y = mx + b

Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).

Let x represent the number of T-shirts and y represent the cost

Therefore we can use any two points to determine the linear equation to represent the model of the line in the form (x, y).

Using the points (6, 84) and  (24, 228). The equation is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-84=\frac{228-84}{24-6} (x-6)\\\\y-84=8x-48\\\\y=8x+36[/tex]

The equation of the linear model is y = 8x + 36

Answers

Answer:

Shirts : $24

Pants : $23.80

Shoes : $21

Ties : $30.60

Step-by-step explanation:

For the shirt : Price = $15 Discount = 20% 2 shirts are bought

Price after the discount = (100% - 20%) x (2 x $15) = $24

For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought

Price after the discount = (100% - 15%) x $28 = $23.80

For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought

Price after the discount = (100% - 40%) x $35 = $21

For the tie: Price = $12 Discount = 15% 3 ties are bought

Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

Answer:

Shirts : $24

Pants : $23.80

Shoes : $21

Ties : $30.60

Step-by-step explanation:

For the shirt : Price = $15 Discount = 20% 2 shirts are bought

Price after the discount = (100% - 20%) x (2 x $15) = $24

For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought

Price after the discount = (100% - 15%) x $28 = $23.80

For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought

Price after the discount = (100% - 40%) x $35 = $21

For the tie: Price = $12 Discount = 15% 3 ties are bought

Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

What is the slope for (-1,2) and (1,16)

Answers

Answer:

The slope is 7.

Step-by-step explanation:

(-1, 2) and (1, 16)

Slope is found using the following formula:

(y₂ - y₁) / (x₂ - x₁)

First, let's label the coordinates (these can be in any order, as long as the second numbers in each coordinate are in the y slots and the first numbers are in the x slots:

y₂: 16

y₁: 2

x₂: 1

x₁: -1

Now, substitute into the original formula:

(y₂ - y₁) / (x₂ - x₁)

(16 - 2) / (1 - (-1))

Simplify

(14)/(2)

7

The slope is 7.

Answers

Answer:

For the first three situations, the sum is zero.

Step-by-step explanation:

As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.

Shawna spends $20 and she earns $20,

So, the sum of the total amount is

-20+20=0

A diver dove down 20.14 feet under-water and then descended 20.14 feet.

First, the diver ascends 20.14 feet then descends the same.

As the ascending and the descending are opposite to each other.

The sum of both is

+20.14-20.14=0

So, in this case, the diver has a sum of zero.

For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,

So, the total points are

+2-2=0

So, in this case, the golfer has a sum of zero points.

In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.

This time, there is an addition of $5.50 to the money you already have.

So, the total money, after receiving the $5.50 is

$5.50+$5.50=$11

In this case, the sum of the total amount is not zero.

Hence, for the first three situations, the sum is zero.

BAC = 58, CAD = 32

Step-by-step explanation:

The angle of BAD is 90 degrees, this is represented by the red outline of a square. This means that adding angles BAC and CAD will equal 90.

15x - 2 + 7x + 4 = 90

Combine common terms

22x + 2 = 90

Solve for x

22x = 88

x = 4

Now you can plug x into the equation for each angle to find its value.

Angle BAC

15x - 2 = 15(4) - 2 = 60 - 2 = 58 degrees

Angle CAD

7x + 4 = 7(4) + 4 = 28 + 4 = 32 degrees

Multiplying both sides by 7 to clear fractions

7*1/7 + 7*3/7(3x - 5) = - 7*41 + 3(3x - 5) = -289x - 15 = - 299x = 15 - 299x = - 14x = - 14/9

Answer:

x = -14/9

Step-by-step explanation:

1/7 + 3/7(3x - 5) = -4

~Subtract 1/7 to both sides

3/7(3x - 5) = -29/7

~Multiply 7 to both sides

3(3x - 5) = -29

~Simplify left side

9x - 15 = -29

~Add 15 to both sides

9x = -14

~Divide 9 to both sides

x = -14/9
