Answer:

y=4x-7

Step-by-step explanation:

We know that the y intercept is -7 so we can have y=mx-7

And we can get the slope by using the slope formula (y2-y1)/(x2-x1)=m

(2,1) (0,-7)

x1 y1 x2 y2

(-7-1)/(0-2)

-8/-2 = 4

m=4

So just plug it into the equation to get:

y=4x-7

Answer:

y = 4x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the t- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (0, - 7)

m = [tex]\frac{-7-1}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4

The line crosses the y- axis at (0, - 7) ⇒ c = - 7

y = 4x - 7 ← equation of line

Answer:

£22.5

Step-by-step explanation:

We would have to split the ratio to 45:45/2 as 2:1 is 2:2/2

Which would give us the answer 45:22.5

Sarah got £22.5

Answer:

B

Step-by-step explanation:

We are given a right triangle with angles 45, 90, and 45

With this type of right triangle, the ratio of the sides are 1:1:square root of 2

We are also given that the hypotenuse is 18

This means that the sides are in the ratio of x:x:x(square root of 2)

Since 18 is the hypotenuse, we can form the equation of-

18 = x(square root of 2)

18/(square root of 2)=x

x= 9 square root of 2

since y=x, y= 9 square root of 2

A cow is eating green grass that grows in a field. The grass in this scenario is the producer.

'This is a basic food chain. The grass is a living organism that utilizes energy from the sun to make its own food through an interaction called photosynthesis. Then, different creatures eat the grass; it is their wellspring of energy.

Every living organism (plants and creatures) should eat food for the endurance of some sort or another. Plants make their own food through an interaction called photosynthesis. Using the energy from the sun, water, and carbon dioxide from the air and nutrients, they artificially make their own food. Since they make or produce their own food they are called makers.

Organisms that don't make their own food should eat either plants or creatures. They are called buyers. A few creatures get their energy from eating plants while different creatures get energy in a roundabout way from plants by eating different creatures that previously ate the plants.

Creatures that eat just plants are called herbivores. Creatures that eat the two plants and other creatures are called omnivores. Creatures that eat just different creatures are called carnivores.

A few creatures eat just dead or decaying materials and are called decomposers.

Answer:

Step-by-step explanation:

We will use a proportion to solve this.

[tex]\frac{2}{4} = \frac{16}{y}[/tex]

Now, we cross multiply.

2y = 16 x 4

2y = 64

Now, we must divide by 2 to get the correct value for y

y = 64/2

y = 32

Now, we can use the same proportion to check our answer.

2(32) = 16 x 4

64 = 64 ✅

Answer:

  y = 1/2

Step-by-step explanation:

The inverse relation means ...

  y = k/x

We can find k from ...

  xy = k = (2)(4) = 8

Then when x = 16, we have ...

  y = 8/x = 8/16 = 1/2

y is 1/2 when x = 16.

Answer:

answer must be $880.

48 papperoni pizza =48 * 15= 720

16 cheese pizza =16 * 10= 160

Total sell =$880

He make $880 for selling pizzas yesterday.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza.

And, Yesterday he sold 64 pizzas in all. For every cheese pizza, he sells 3 pepperoni pizzas.

Now,

Since, For every cheese pizza, he sells 3 pepperoni pizzas.

Hence, Let number of cheese pizza = x

Then, Number of pepperoni pizzas = 3x

Since, Yesterday he sold 64 pizzas in all.

So, We get;

⇒ x + 3x = 64

⇒ 4x = 64

⇒ x = 16

Thus, Number of cheese pizza = x = 16

Then, Number of pepperoni pizzas = 3x

                                                      = 3 × 16

                                                      = 48

So, The cost of 16 cheese pizza and 48 pepperoni pizza are;

⇒ Total cost = 16 × $10 + 48 × $15

⇒ Total cost = $160 + $720

⇒ Total cost = $880

Thus, He make $880 for selling pizzas yesterday.

Answer:

Step-by-step explanation:

Well all you really need to do is add 31 and 104 which is 135 then divide it by 3 and well you got the answer 45

The expression (31 + 104) / 3 is equal to 45.

The expression that represents the sum of 31 and 104, divided by 3, can be written as (31 + 104) / 3.

To calculate the value, we start by evaluating the sum of 31 and 104, which gives us 135. So, the expression becomes 135 / 3.

Dividing 135 by 3 yields a result of 45.

Therefore, (31 + 104) / 3 is equal to 45.

The expression simplifies the process of finding the sum of the two numbers (31 and 104) by first adding them together and then dividing the sum by 3. This calculation provides a concise representation of the desired arithmetic operation and its solution.

Answer:

[tex]\boxed {\boxed {\sf (-8,-7)}}[/tex]

Step-by-step explanation:

When a point is reflected over y=-x, the following change occurs:

[tex](x,y)[/tex]    ⇒  [tex](-y, -x)[/tex]

We are given the point (7,8).

Essentially, we change the signs for both coordinates, then flip the x-coordinate and y-coordinate.

1. Change the signs

[tex](7,8)[/tex]    ⇒    [tex](-7,-8)[/tex]

2. Flip the x and y coordinates

[tex](-7,-8)[/tex]   ⇒    [tex](-8,-7)[/tex]

So the image of (7,8) after a reflection over y=-x is (-8,-7)

Step-by-step explanation:

Evaluate 2 x 2 x 2 x 3 x 11 (better written as 2·2·2·3·11, because "x" is a variable name, not a math operator).

2·2·2·3·11 = 8·33 = 264

Then divide 792 by this 264 to find the final factor:

final factor = 792/264 = 3

Then the prime factorization of 792 is 2·2·2·3·3·11

which we obtained by multiplying 2 x 2 x 2 x 3 x 11 by 3.
