(Inequalities) what do you have to do when multiplying or dividing by a negative number?

Answers

Answer:

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.

Step-by-step explanation:

You are welcome.

And I hope this helps.      :)

Answer:

Step-by-step explanation:

If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality.  Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive.  Generally you can either multiply every term in the given inequality by -1 or divide every term by -1.  In both cases you must change the direction of the inequality sign.

Example:  Given -3x > 2 + 5y, solve for x.  To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right.  We must reverse the direction of the inequality sign, so the final answer is  x < -2/3 - (5/3)y.

-4x+y=23 and 4x-9y=-15

Answers

Answer:  x= -6; y= -1

Step-by-step explanation:

-4x + y = 23

4x - 9y = - 15

-4x + y = 23

      y = 23 + 4x     [Add 4x to both side]

4x - 9(23 + 4x) = - 15

4x - 207 - 36x = - 15

-32x - 207 = -15

-32x = 192             [Add 207 to both side]

    x = -6                [Divide -32 from both side]

-4x + y = 23

-4(-6) + y = 23          [Plug in -6 for x]

24 + y = 23              [Subtract 24 from both side]

       y = -1

Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a

If time is four hours from now, the time left till midnight would be quarter that if it is one hour from now. What time is it now?

Answers

Answer:

The time now is 7 pm

Step-by-step explanation:

Suppose that now is the time T.

We know that:

"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".

Then:

if we define midnight as 12, and we assume that T is in the pm range.

Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))

With this in mind, we can write the problem as:

12 - (T + 4) = (1/4)*( 12 - (T + 1))

Now we can solve this for T.

12 - T - 4 = (1/4)*(12 - T - 1)

8 - T = (1/4)*(11 - T)

4*(8 - T) = 11 - T

32 - 4*T = 11 - T

32 - 11  = -T + 4*T

21 = 3*T

21/3 = T

7 = T

Then T = 7 pm

The time now is 7 pm

Madelyn uses 58 beads to make a necklace. She plans to sell 36 necklaces at
each craft fair she goes to this summer. She plans to go to 4 craft fairs this
summer. What is the total number of beads that Madelyn will use to make the
necklaces she plans to sell at the 4 craft fairs?

Answers

58x36=2088 (the total of beads used at 1 crafts fair)

Take that total and multiply it with 4
2088x4 =8352 (total amount of beads for 4 craft fairs)
58 beads for 1 necklace
X beads for 144 necklaces
X= 58•144/1
X= 8,352 beads

36 necklaces at each fair, she is planing on going to 4 fairs, 36•4=144. She is planing on selling 144 necklaces.

Answer is: 8,352 beads

C. [tex]\frac{9}{17}[/tex] lb per person

D. 36 people

Answers

Answer:    1/4

Answer:

Step-by-step explanation:

Here is the complete question: Find the rate of change for the situation:

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.

Given: 1st situation, A chef cook 9 lbs chicken for 36 people.

          2nd situation, chef cook 17 lbs chicken for 68 people.

∴ 1st situation, weight of chicken per person=  

 Weight of chicken per person=  

2nd situation, weight of chicken per person=  

Weight of chicken per person=  

In both the situation chef cook same amount of chicken per person, which is  

∴ Rate of change is

Step-by-step explanation:

There are several important information's already given in the question. Based on those information's the answer can be easily deduced.

In the first case,

The amount of chicken the chef cooks for 36 people = 9 pounds

Then

The amount of chicken the chef cooks for 1 person = 9/36

                                                                                 = 1/4 pounds

Now let us take the second case

The amount of chicken the chef cooks for 68 people = 17 pounds

Then

The amount of chicken the chef cooks for 1 person = 17/68

                                                                                 = 1/4 pounds

From the above deductions, it can be concluded that the correct option among all the options given in the question is the third option or option "B".

Read the poem.The Whippoorwillby Madison Julius CaweinI. Above lone woodland ways that led To dells the stealthy twilights tread The west was hot geranium red; And still, and still, Along old lanes the locusts sow With clustered pearls the Maytimes know, Deep in the crimson afterglow, We heard the homeward cattle low, And then the far-off, far-off woe Of "whippoorwill!" of "whippoorwill!"II.
