Which liner equality will not have a shared solution set with the graphed liner inequality
Morgarella [4.7K]

The linear inequality wthat will not have a shared solution set with the graphed linear inequality is C. y > 5/3x + 2.

<h3>How to illustrate the information?</h3>

It should be noted that the graph shows the shaded area as y < 5/3x + 1.. The slope of the line will be 5/3.

The two parallel lines are the same. The graph of the inequality is also attached.

The complete question is:

Which linear inequality will not have a shared solution set with the graphed linear inequality?

A. y < 5/3x – 2

B. y < -5/3x + 1

C. y > 5/3x + 2

D. y > -5/3x + 2

A concession stand sells hamburgers (h) for $2 and hotdogs(d) for $1.On friday night they sold a total of 300 hamburgers and hot
Olegator [25]
The first equation has to be the sum of hotdogs and hamburgers. Since a total of 300 <span>hamburgers and hotdogs was sold, the first equation is:
          h+d=300

Now, the second equation is about the money. They say that EACH hamburger cost $2 and each hotdog cost $1. And, the total amount of money made was $420. So the second equation is:

      2h+d=420

SO, overall, the system of equations is this:

   
h+d=300
   2h+d=420
     
(option A is the answer)

Which of the following could be the probability distribution for a loaded number cube?
Ierofanga [76]
<h3>Answer: Choice B</h3>

=======================================================

Explanation:

The requirements for a probability distribution are this

  1. The individual probabilities must be between 0 and 1, inclusive of both endpoints. We can say 0 \le p \le 1 where p is an individual probability.
  2. The probabilities must sum to 1.

Condition #1 shown above allows us to rule out choice C due to -0.10 not being in the interval from 0 to 1.

We can also rule out choice D since the probabilities sum to this

0.20+0.15+0.20+0.20+0.20+0.20 = 1.15

The sum is too large. The sum needs to be 1.00 or just 1.

So that leaves choice A or choice B as the possible answer. Both distributions fit conditions #1 and #2 as shown above (I'll let you confirm these facts). However, choice A is ruled out because that distribution is considered fair. Each probability for choice A is equal, so each side of the cube is equally likely to be landed on.

For choice B, the probabilities are different, so we don't have a fair cube here and it is considered loaded or biased.

Answer:

  D.  right 4, down 8

Step-by-step explanation:

The usual transformations applied to functions are ...

  f(x) ⇒ f(x -h) . . . . translation right h units

  f(x) ⇒ f(x) +k . . . . translation up k units

  f(x) ⇒ k·f(x) . . . . . vertical scaling by a factor of k; reflection over x-axis when k < 0

  f(x) ⇒ f(x/k) . . . . . horizontal scaling by a factor of k; reflection over y-axis when k < 0

In the above, "scaling" will be expansion when |k| > 1, compression when |k| < 1.

__

Your transformation is ...

  x^2 ⇒ (x -4)^2 -8

  f(x) ⇒ f(x -4) -8

This is translation with h=4 and k=-8. That is, it is translation right 4 units and down 8 units.

_____

<em>Additional comment</em>

Like much of math, it is all about matching patterns.
