Answer:

y = 2x - 4

Step-by-step explanation:

Can I ask which variable you are solving?

PS I will assume you need the formula y=mx+b

-2x + y = - 4

Here you would translate the m and x variables to the right side making them positive.

y = 2x - 4

Now the formula is in proper form

Hey :)

If you are solving for x, the answer is: x = y/2 + 2

-2x + y = -4

Subtract y from both sides

−2x = −4 − y

The equation is in standard form:

−2x = − y −4

Divide both sides by −2:

-2x/-2 = -y - 4/-2

 

Dividing by −2 undoes the multiplication by −2

x = -y -4/-2

Divide −4 −y by −2

x = y/2 + 2

However, if you are solving for y, the answer is: y = −4 + 2x

−2x + y = −4

Add 2x to both sides:

y = −4 + 2x

Hope this helps!

An ice cream machine produced 45 ice cream sandwiches per minute. After reconditing, its speed increased to 54 ice cream sandwic
Tanya [424]
<h2>Percent of speed the machine increase is 20%</h2>

<h2>Given that;`</h2>

Number of ice cream produced before = 45

Number of ice cream produced after = 54

<h2>Find:</h2>

Percent of speed the machine increase

<h2>Computation:</h2>

Percent of speed the machine increase = [Number of ice cream produced after - Number of ice cream produced before] / Number of ice cream produced before

Percent of speed the machine increase = [(54 - 45) / 45]100

Percent of speed the machine increase = [9 / 45]100

Percent of speed the machine increase = 20%

Please please, please
Masja [62]

The production of health drink cans at a warehouse can be represented by the equation below, where x represents the hours of production, and y the total supply of items in the warehouse, in hundreds.

Which of the following graphs represents this situation?

the equation is y= 3/5x+2

I drew the graph.

3/5 is the slope, and 2 is the y-intercept. So you start at (0,2), and go up 3 units, then right 5.

Please answer number 1 and 2 with ABC or D
Free_Kalibri [48]

Answer:

1. (a) a+b=86

2. (c) 5.99a+9.99b≤600

Step-by-step explanation:

1.

a = amount of 16gb memory sticks

b = amount of 21gb memory sticks

Gary is buying a memory sticks for each of the 86 teachers. Therefore the total sum of both 16gb and 32gb memory sticks should equal 86:

a+b=86

2.

a = amount of 16gb memory sticks

b = amount of 21gb memory sticks

Each 16gb memory stick cost $5.99, and each 32gb one costs $9.99. Therefore...

5.99a = total cost of 16gb memory sticks

9.99b = total cost of 32gb memory sticks

Gary has to spent an amount less than or equal to $600. Therefore, the total sum of the costs of both 16gb and 32gb memory sticks should be less than or equal to 600:

5.99a+9.99b≤600

Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8
Lina20 [59]

Answer : B x 1 2 3 4 y 3.2 6.4 9.6 12.8

WE analyze the first option A

x -- y -- Difference

8 -- 20

9 -- 22.5 -- 2.5

10 -- 25 -- 2.5

11 -- 27.5 -- 2.5

From the first function we can see there is a constant difference of 2.5.

We analyze the second option B

x -- y -- Difference

1 -- 3.2

2 -- 6.4 -- 3.2

3 -- 9.6 -- 3.2

48 -- 12.8 -- 3.2

From the second function we can see there is a constant difference of 3.2

3.2 is the greatest

So second function B has the greatest constant of variation.
