Jason volunteered at the pet shelter twice as many times as keith. Noah volunteered three times more often than jason. Keith vol
Alchen [17]

Answer:

y = 6\cdot z

y - Number of times that Noah volunteered at pet shelter.

z - Number of times that Keith volunteered at pet shelter.

Step-by-step explanation:

After reading the statement of the problem, the following variables are described below:

x - Number of times that Jason volunteered at pet shelter.

y - Number of times that Noah volunteered at pet shelter.

z - Number of times that Keith volunteered at pet shelter.

The following two relations are presented herein:

Noah and Jason

y = 3\cdot x

Jason and Keith

x = 2\cdot z

The relationship between the number of times Noah and Keith volunteered is:

y = 6\cdot z

1.The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD? 2.The equation of line A
gogolik [260]
So here's how to do it,
slope intercept form is y=mx+b
m is the slope, b is the y- intercept, X is your unknown variable.

you need to solve to get y by its self to get your slope.

for perpendicular lines flip the slope

ex 1, smy=2x+6 --- slope of a perpendicular line will be 1/2

ex 2, y=3/2+8 ---8 perpendicular lien would have a slope of 2/3

parallel lines have the same slope so any equation with with the same slope will be parallel if it has the same degree.

ex. y=2x+14 is parallel to y= 2x+56

slope can be found using the following formula if you have two sets of points on the same line

m= y2-y1 ÷ X2 - X1

Kruka [31]
1 dozen = 12

Divide 941 by 12:

941 / 12 = 78.42

So the greatest number of dozens he can make is 78.

A coordinate plane with a line passing through points (1, 2) and (4, 4)
Kobotan [32]

A straight line is represented by a linear equation given below.

The points are given as (1, 2) and (4, 4).

Start by calculating the slope (m)

m=\frac{y_2-y_1}{x_2-x_1}

So, we have

m=\frac{4-2}{4-1} \\m=\frac{2}{3}

<h3>What is the slope-intercept form of the line?</h3>

The equation in slope-intercept form is then calculated as:

y=m(x-x_1)+y_1

So, we have:

y=\frac{2}{3}(x-1)+2\\ \\y=\frac{2}{3}(x-4)+4\\

Expand

y=\frac{2}{3}(x-1)+2\\ y=\frac{2}{3} x-\frac{2}{3}+2

Take LCM

y=2/3x+4/3

Multiply through by 3

3y=2x+4

So, the possible equations are:

.3y=2x+4\\y=\frac{2}{3}x+\frac{4}{3} \\y=\frac{2}{3}(x-1)+2\\y=\frac{2}{3}(x-4)+{4}
