Determine whether (2,-1) and (-4,2) satisfy the inequality 2x-3y>4. Neither (2,-1) nor (-4,2) satisfies the inequality. (-4,2) satisfies the inequality, but (2,-1) does not. (2,-1) satisfies the inequality, but (-4,2) does not. Both (2,-1) and (-4,2) satisfy the inequality.
Answer:
(2,-1) satisfies the inequality, but (-4,2) does not.
Step-by-step explanation:
To verify if the points satisfy the inequality, we replace then in the inequality, and see if we have a true statement or a false one.
(2,-1)
[tex]x = 2, y = -1[/tex]
So
[tex]2x - 3y > 4[/tex]
[tex]2(2) - 3(-1) > 4[/tex]
[tex]4 + 3 > 7[/tex]
[tex]7 > 4[/tex]
This is a true statement, which means that (2,-1) satisfies the inequality.
(-4,2)
[tex]x = -4, y = 2[/tex]
So
[tex]2x - 3y > 4[/tex]
[tex]2(-4) - 3(2) > 4[/tex]
[tex]-8 - 6 > 7[/tex]
[tex]-14 > 4[/tex]
This is a false statement, so (-4,2) does not satisfy the inequality.
The correct answer is:
(2,-1) satisfies the inequality, but (-4,2) does not.
A pair of weak earthquakes is modeled by a system of inequalities. One earthquake occurred roughly 20 km east and 14 km north of the center of Columbia, NC. The quake could be felt from 25 km away. A couple days later, another earthquake occurred 8 km west and 3 km north of the center of Columbia and could be felt from 14 km away. If Columbia is located at (0, 0) on a coordinate grid, the system of inequalities represents this scenario.
StartLayout Enlarged left-brace first row (x minus 20) squared + (y minus 14) squared less-than-or-equal-to 625 second row (x + 8) squared + (y minus 3) squared less-than-or-equal-to 196 EndLayout
Which location relative to Columbia felt both earthquakes?
4 km west and 12 km south
6 km west and 4 km north
2 km east and 10 km north
6 km east and 8 km north
Answer:
2 km east and 10 km north
Step-by-step explanation:
I did the activity and got the right answer.
By evaluating the inequalities, we will see that the correct option is: 2 km east and 10 km north
Which location will feel both earthquakes?
Here we have the inequalities:
(x - 20)^2 + (y - 14)^2 ≤ 625
(x + 8)^2 + (y - 3)^2 ≤ 196
Where, x is the distance due east, and y is the distance due north.
So we just need to find which of the given options makes both inequalities true, for example, for the first one we have:
x = -4
y = -12
Replacing that on the first inequality we get:
(-4 - 20)^2 + (-12 - 14)^2 ≤ 625
1,252 ≤ 625
This is false, so this option is not correct.
Now we just need to check the other options. Particularly for the third we have:
x = 2
y = 10
Replacing that in both inequalities we get:
(2 - 20)^2 + (10 - 14)^2 ≤ 625
340 ≤ 625 (true).
(2 + 8)^2 + (10 - 3)^2 ≤ 196
149 ≤ 196 (true)
So at 2km east and 10km north of Columbia, the two earthquakes can be felt.

Given the set of integers 1 − 20 , what is the probability of selecting a number that is divisible by 7 ?
The probability of selecting a number that is divisible by 7 is [tex]\frac{1}{10}[/tex].
What is probability?Probability deals with finding out the likelihood of the occurrence of an event.
It measures the chance of an event happening and is equal to the number of favorable events divided by the total number of events.
The value of probability ranges between 0 and 1, where 0 denotes uncertainty and 1 denotes certainty.
Given
Set of integers = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
The probability of selecting a number that is divisible by 7 :
We all know the 7 multiples less than 20 : 7, 14
There are 2 numbers that are divisible by 7 in the set of integers 1 - 20
Therefore, Number of favorable outcomes n(E) = 2
Total number favorable outcomes n(S) = 20
Probability is the ratio of number of favorable outcomes to total number of favorable outcomes.
[tex]P(E) = \frac{n(E)}{n(S)}[/tex]
[tex]P(E) = \frac{2}{20} =\frac{1}{10}[/tex]
Hence,
The probability of selecting a number that is divisible by 7 is [tex]\frac{1}{10}[/tex].

Suppose the sequence {an} is arithmetic with a3 = 15, d = -3/2, and an=6
Find n.
Answer:
The value of n = 9th term
Step-by-step explanation:
Given:
In an arithmetic series
a3 = 15
d = -3/2
an = 6
Find:
The value of n
Computation:
In an arithmetic series
An = a + [n - 1]d
where,
An = last term
a = first term
n = number of term
d = common difference
So,
a3 = a + 2d
15 = a + 2(-3/2)
15 = a - 3
a = 18
An = a + [n - 1]d
6 = 18 + [n - 1][-3/2]
-12 = [n-1][-3/2]
8 = n - 1
The value of n = 9th term

Frederick's salary varies directly with the hours he works. Last week I earned $ 328.30 and worked 33.5 hours. If he works 35 hours this week, what will be his salary from him?
Answer:
His salary will be of $343.
Step-by-step explanation:
Frederick's salary varies directly with the hours he works.
This means that this question can be solved by proportions, using a rule of three.
We have that:
For 33.5 hours, he earned $328.30. How much he earns for 35 hours?
33.5 hours - $328.30
35 hours - $x
Applying cross multiplication:
[tex]33.5x = 328.30*35[/tex]
[tex]x = \frac{328.30*35}{33.5}[/tex]
[tex]x = 343[/tex]
His salary will be of $343.

Given:
The radius of the circle = 12 in.
The central angle of the intercepted arc PQ = 135 degrees.
To find:
The measure of arc PQ.
Solution:
The length of arc is:
[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle.
Substituting [tex]r=12,\pi=3.14,\theta=135^\circ[/tex] in the above formula, we get
[tex]s=2(3.14)(12)\times \dfrac{135^\circ}{360^\circ}[/tex]
[tex]s=75.36\times 0.375[/tex]
[tex]s=28.26[/tex]
[tex]s\approx 28.3[/tex]
The measure of arc PQ is 28.3 in. Therefore, the correct option is (d).

Answer:
y = -2x + 1.5
Step-by-step explanation:
line that passes through the given points (-1,3.5),(1,-0.5), (3,-4.5)
slope (m) = (-0.5 - 3.5) / (1 - -1) = -4 / 2 = -2
(y - -4.5) / (x - 3) = -2 ... pass (3,-4.5)
y + 4.5 = -2x +6
y = -2x + 1.5
