Answer:

y=-3x+5

Step-by-step explanation:

concepts: y=mx+b is slope intercept equation formula

m=slope

b= y intercept

Therefore we need to find the slope and y intercept

first find slope

m=\frac{y2-y1}{x2-x1}

let y2 be 2

let y1 be -4

let x2 be 1

let x1 be 3

\frac{2-(--4)}{1-3}

6/-2 = -3

m=-3

slope is -3

y= -3x+ b

we need find y intercept now

just plug in (1,2) into that equation

2=-3(1)+b

b=5

y=-3x+5

A baker uses a coffee mug with a diameter of 8 cm 8 cm8, start text, space, c, m, end text to cut out circular cookies from a bi
horsena [70]

Answer:

Step-by-step explanation:

The diameter of the top of the coffee mug which the baker uses to cut out circular cookies from the big sheet of cookie dough is 8 cm.

Radius of the coffee mug is diameter of the coffee mug/2.

Radius of the coffee mug

= 8/2 = 4cm

The area of the circular mug is expressed as

Area = πr^2

Where π is a constant whose value is 3.14

Therefore,

Area of the top of the circular mug = 3.14 × 4^2 = 3.14 × 16 = 50.24 cm^2

The area of the top of the circular cup is the same as the area of each cookie. Therefore,

The area of each cookie is 50.24 cm^2

Identify the independent and dependent quantities from the function’s verbal description. What is the independent quantity, and
ad-work [718]

Question:

What is the independent quantity, and which variable should represent it?

Answer:

They're independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages.

Explanation:

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is the one that depends on the value of some other number. ... Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

Sorry i'm 5 days Late, But i hope this clears up any confusion for anyone!
