Is (0,0) a solution to this system? y ≤ x^2 + x - 4 y < x^2 + 2x + 1

Mathematics

yaroslaw [1]2 years ago

( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.

<h3>What is inequality?</h3>

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than’

Finding the solution for the inequality is as follows:-

y ≤  x² +x-4 by putting x and y equal to 0.

0 ≤ 0 + 0 -4

0 ≤ - 4

This is incorrect so (0,0) can not be the solution for this inequality.

y < x²+2x+1.

0 < 0 + 0 + 1

0 < 1

This inequality is showing the solution for (0,0)

Therefore ( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.

You earn $9.50 per hour at your summer job. Write and solve an inequality to find the number of hours you need to work to buy a
masha68 [24]
Let
h
represent hours worked.
Now, we know the pay for one hour of work is
$
9.50
. So, the amount of pay for
h
hours worked is given by
9.50
h
.
Furthermore, since we're saving for a camera that costs
$
247
,
we want at LEAST
$
247
(but it's okay if we have more). So, we'll be using
≥
in the inequality.
So, our inequality is
9.50
h
≥
247

To solve, we simply divide both sides by
9.50
:
h
≥
247
9.50

h
≥
26

You need to work at least
26
hours to buy the digital

A political analyst conducted an observational study in 2014 that measured the rate of voter dissatisfaction with the United Sta
Ilia_Sergeevich [38]

Based on the results of the study, the conclusion which is valid is There is correlation between the increase in the rate of televised political attack ads since the previous congressional election and the rate of voter dissatisfaction in the observed districts.

<h3>What does the study conclude?</h3>

The study showed that the rate of voter dissatisfaction in the districts since the previous election cycles is similar to the rate of increase of televised political attack ads.

The fact that both the rate of voter dissatisfaction and televised political attack ads moved together means that they correlate with each other.

It is important to note however, that correlation does not equate causation so there might be no link between the two rates.

HURRY!!! Which inequality has –12 in its solution set? A B C D x + 6 less-than negative 8 x + 4 greater-than-or-equal-to negativ
frozen [14]

Answer:

<u>The correct answer is D.  x + 5≤ - 4</u>

Step-by-step explanation:

Let's review which inequality has - 12 in its solution set, this way:

A. x + 6 less-than negative 8

-12 + 6 < - 8

-6 < - 8 Not correct

B. x + 4 greater-than-or-equal-to negative 6

- 12 + 4 ≥ - 6

- 8  ≥ - 6 Not correct

C. x minus 3 greater-than negative 10

- 12 - 3 > - 10

<u>- 15 > - 10 Not correct</u>

D. x + 5 less-than-or-equal-to negative 4

- 12 + 5 ≤ - 4

- 7 ≤ - 4 This is correct

<u>The correct answer is D.  x + 5≤ - 4</u>
