Write a direct variation equation that relates 16 and 2

Answers

Answer 1

Answer:

16 = 2x

Step-by-step explanation:

The pattern for a direct variation equation is y = kx

y is the "output" or result

k is the "constant" a number that doesn't change in the equation.

x is the "unknown" variable that makes the output of the equation true when found.

Here x=8

16 = 2(8)

Answer 2

Answer:

16 = 2x

Answer: y = 16x   or  C = 16×f  

The number of cookies is 16 for each cup of flour used

Step-by-step explanation:

You can take numbers from the graph. For example, Number of Cookies: 192 and the Cups of flour: 12.  Divide the number of cookies by the amount of flour

192÷12 = 16

Check other numbers to be sure  96÷6 = 16

288÷18 = 16

You could fill in the chart by multiplying Cups of Flour by 16 to find the number of Cookies

C = 16 × f

C = 16 × 3

C = 48

Y=16x while C=16xf. the answer is 16

find an equation of the line that has a y intercept of 5 and is perpendicular to the graph of the line 4x+3y=8.

Answers

Answer:

3x-x+2=4

Step-by-step explanation:

You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.

Answer:

y = 3/4x + 5

-3x + 4y = 20

Step-by-step explanation:

In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)

First change that standard form equation to slope-intercept form:

1. 4x + 3y = 8

2. 3y = -4x + 8

3. y = -4/3x + 8/3

Step 1 is given.

In step 2, 4x was subtracted from both sides.

In step 3, both sides were divided by 3.

Slope-intercept form:

y = mx + b

m is the slope and b is the y-intercept.

m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)

b = 5; the y-intercept was stated in the problem

Now, you put it together: y = 3/4x + 5

Standard form:

You can just change the slope intercept form back into standard form by moving the numbers around a bit:

1. y = 3/4x + 5

2. -3/4x + y = 5

3. -3x + 4y = 20

Step 1 is given.

In step 2, 3/4x was subtracted from both sides of the equation.

In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

Is Frieda’s work correct? Explain how she can check her solution.
z + 22 = 64
z + 22 – 22 = 64 – 22
z = 42

Answers

Answer:

Frieda should substitute 42 for z in the original equation, and simplify to see if it is a true statement. 42 + 22 = 64, so her solution is correct
