Answer 1

Answer:

Answer:

5.) Proportionality is 3/1 or 3 simplified

b x 3 = p
b= boxes
p= pens in box

6.) Proportionality is 1/6

m ÷ 6 = p
m = muffins
p= pack(s) of muffins

Step-by-step explanation:

You would take the first column (or in this case row (pens and packs) and place the 2nd row under it in fraction form.

5.) 3/1 = 3
6.) 1/6 = 1/6

That would be your proportion

Then you would (in place of numbers) use letters to symbolize in the equation

5.) p = pens: b= boxes
6.) m= muffins; p= pack

Then create an equation to figure out how to get the correct numbers.

1 box holds 3 pens so:
5.) b x 3 = p
Check: 2 boxes x 3 pens per box = 6 pens (check table) Correct!
6 muffins in 1 pack so:
6.) m ÷ 6 = p
12 muffins ÷ 6 muffins in per box = 2 packs (check table) Correct!

Write the equation of the line described below in slope-intercept form. m = 6, b = 2

Answers

The slope-intercept format is 'y = mx + b'

Knowing this, we can just input the given values into the format.

y = 6x + 2

If you need me to explain anything in more depth, just ask :))

Which equation represents the line shown in the graph below? A. y = 2x - 3

B. y = -3y + 2

C. y = 3y - 2

D. y = -3y - 2

Answers

The equation used to for slope intercept form is commonly used.

y = mx + b

Let us find the y-intercept first.

The place where the line crosses the y axis is 2.

y = mx + 2

Now, find the slope.

Find two points on the line, then solve.

$m = (y2 - y1)/(x2 - x1)$

Alright, I found two points on the line:- (-2,8) and (2, -4)

$m= (-4 - 8)/(2--2)$

m = -12/4
m = -3

The slope is -3. The y-intercept is 2

Lets put them into the equation

y = -3x + 2

Final answer: B. y = -3x + 2

The equation that represents the line shown in the graph is:

B. y = -3x + 2

Further explanation

Solving linear equation mean calculating the unknown variable from the equation.

Let the linear equation : y = mx + c

If we draw the above equation on Cartesian Coordinates , it will be a straight line with :

m → gradient of the line

( 0 , c ) → y - intercept

Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :

$\large {\boxed {m = (y_2 - y_1)/(x_2 - x_1)}}$

If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :

$\large {\boxed {y - y_1 = m ( x - x_1 )} }$

Let us tackle the problem!

From the graph , the line goes through the point ( -1 , 5 ) and ( 0 , 2 ).

Let:

( x₁ , y₁ ) = ( 0 , 2 )

( x₂ . y₂ ) = ( -1 , 5 )

$\texttt{ }$

We can calculate the gradient of the graph by using this following formula:

$m = ( y_2 - y_1 ) / ( x_2 - x_1 )$

$m = ( 5 - 2 ) / ( -1 - 0 )$

$m = 3 / (-1)$

$m = -3$

$\texttt{ }$

Next , we can find the equation of the graph by using this following formula:

$y - y_1 = m ( x - x_1 )$

$y - 2 = -3 ( x - 0 )$

$y - 2 = -3x$

$y = -3x + 2$

$\texttt{ }$

Find the surface area

Answers

Surface Area formula of a cylinder:
S.A = 2 × Area of base + Perimeter of base × Height of prism
= 2 $\pi$ r² + 2 $\pi$ rh
= 2 $\pi$ (5)² + 2 $\pi$ (5)(18)
= 50 $\pi$ + 180 $\pi$
= 230 $\pi$ in² ( in terms of $\pi$ )
= 722.566 in²
= 722.7 in² ( to the nearest tenth )

Suppose you have a large coffee can full of pennies. How can you estimate how much money that can contains without counting all the coins?

Answers

if you know how much a penny weighs then you can weigh any amount of pennies and take that weight and divide by the weight of one penny, to get how many there are without counting all the coins.
