Answer:

4 packages

Step-by-step explanation:

We have to do 980/250.

So after you get that, you would get 3.92. It would not make sense to get 3.92 packages since that isn't possible on Amazon using common sense. Therefore we must round 3.92 to 4 packages.

Answer:

Ms.Dangerfeild should order 4 bags

Step-by-step explanation:

250 times 4 is 1000 so Ms.Dangerfeild will have 20 extra erasers.

Answer:

B

Step-by-step explanation:

m = 3/4

x1 = 2

y1 = 1

Using the formula,

y - y1 = m(x - x1)

y - 1 = 3/4(x - 2)

y - 1 = 3x/4 - 3/2

y = 3x/4 -3/2 + 1

y = 3x/4 - 1/2 (×4)

4y = 3x - 2

Therefore, the answer is B

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line that passes through (2, 1) and 3/4 as its slope.

4y = 3x - 2

Option B is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = 3/4

m = 3/4

The point that passes through = (2, 1)

Now,

The equation of the line is y = mx + c.

y = (3/4)x + c

We will take (2, 1) = (x, y) since it passes through the line.

1 = (3/4)2 + c

1 = 3/2 + c

c = 1 - 3/2

c = -1/2

Now,

The equation of the line that passes through (2, 1) and 3/4 as its slope.

y = (3/4)x -1/2

y = (3x - 2)/4

4y = 3x - 2

Thus,

The equation of the line that passes through (2, 1) and 3/4 as its slope.

4y = 3x - 2

Option B is the correct answer.

Answer:

  x = 12/a

Step-by-step explanation:

To find the value of x, divide both sides of the equation by its coefficient.

  ax = 12

  (ax)/a = 12/a

  x = 12/a

Answer:  y = 7x - 3

graphed equation attached

Step-by-step explanation:  Slope-intercept form . y= mx+b

m is the slope, b is the constant, the y-intercept.

First find the slope:  rise/run  

Rise is the difference in y-values  18-4 = 14

Run is the difference between x-values  3 - 1 = 2

The Slope is 14/2   simplify:

m = 7

Use this calculated slope with values of y and x from either of the given coordinates and calculate b

y = mx + b

18 = 7(3) + b

18 = 21 + b .  subtract 21 from both sides  18 - 21 = 21 -21 + b

-3 = b

Put these calculated values for m and b into the slope-intercept equation"

y = 7x - b

[tex] {x}^{2} + 6x[/tex]

Answer:

B.) -1

Step-by-step explanation:

Here, 3x + 2(x - 9) = 8x + x - 14 is given

Now, we will solve and we get,

3x + 2(x - 9) = 8x + x - 14

3x + 2x - 18 = 9x - 14

5x - 9x = 18 - 14

-4x = 4

4x = -4

x = -4÷4

x = -1

Thus, The value of x is -1

Hence, Option B is correct

Answer:

wow

Step-by-step explanation:

You earnin monnnnnneyyyyyyyyy!!!!!!!!!!!!!!!!!!!

Step-by-step explanation:

x+y=180

x=180-y------(i)

x-y=70------(ii)

Now,

Putting the value of x in equation (ii)

x-y=70

(180-y)-y=70

180+2y=70

2y=70-180

2y= - 110

y= - 110/2

y= - 55

Again,

x=180-(-55)

x=235

x-y=70

x-(-55)=70

x+55=70

x=70-55

x=15

Answer:

y = 17.5

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 35 when x = 140, then

35 = 140k ( divide both sides by 140 )

0.25 = k

y = 0.25x ← equation of proportion

When x = 70, then

y = 0.25 × 70 = 17.5

Answer:

Meanings of the numbers:

Most numbers represent an amount. Positive numbers represent above zero. Zero is the only number that does not represent an amount. It means nothing. When you go lower than nothing, you are in the negative numbers. Negative numbers represent absent values pretty much.

How I would use them in every day life:

I would use positive numbers to represent... maybe something I'm trying to get at a store. Ex: 4 bananas

I would use negative numbers to... maybe look at the temperature. Ex: -16 degrees Fahrenheit. Negative numbers are in temperature all the time.

Answer: B. Controlled experiment

Step-by-step explanation:

This is a controlled experiment because the variables in the question are manipulated by the researcher. We are told that while one group watches television before going to sleep, the other group does not.

The controllers won't have control over the variables that were used if it was an observational study while for a survey, it has to do with collection of information regarding certain topics or happenings in order to have people's perception on the topic or area of interest.

Answer:

The instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].

Step-by-step explanation:

We have the position as the function

[tex]s(t) = -2 - 6t[/tex]

As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.

so finding the derivate of  [tex]s(t) = -2 - 6t[/tex]

∴ [tex]s'(t)=-6[/tex]

The instantaneous velocity at [tex]t = 2[/tex]

[tex]s'(2)=-6[/tex]

Therefore, the instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].

Please note that the negative value indicates the direction of movement, in this case, it would be backward.

Answer:

Step-by-step explanation:

Answer: ∠ECB = 60°

Step-by-step explanation:

First, find the value of x by adding them up.

x + 3x + 2x = 6x

Since we know that all of the angles create a 180° angle, we can set up a proportion.

6x = 180°

To find the value of x, divide both sides by 6.

6x ÷ 6 = x

180 ÷ 6 = 30

So now the proportion is x = 30.

Now that we now x = 30, we can plug in 30 to the angle measures.

∠DCA = 30°

∠DCE = 90°

∠ECB = 60°

So angle ECB is 60°.
