solving the equation given to us first:
-5x/2 = 5/1 ( ignore the ≤ symbol for now and replace with =) and cross multiply
you will get
-5x = 10
x = -10/5 ( minus doesn't stay in denominator so so we take up to numerator )
x = -2
so x ≤ -2
NOTE: if we have ≤ we shade the dot but if we have just < or we don't shade the dot.
soooo
x ≤ -2 will be going backwards
so the answer is option (C).
Hope this helps.
Good luck.

Or 15 true false and 5 short answer
Or 26 true false and 2 short answer
Step-by-step explanation:
let x be the number of true-false questions

Then we have to solve the equation 3x + 11y = 100
Important: x and y are natural numbers
3x + 11y = 100 ⇔ 100 - 11y = 3x
If y=10 ⇒ 100 - 11×10 = −10 = 3x impossible because x ≥ 0
If y=9 ⇒ 100 - 11×9 = 1 = 3x impossible because x is a natural number
If y=8 ⇒ 100 - 11×8 = 12 = 3x ⇒ x = 12/3 = 4
Then (x,y) = (4,8) is a solution to the equation
If y=7 ⇒ 100 - 11×7 = 23 = 3x impossible because x is a natural number
If y=6 ⇒ 100 - 11×6 = 34 = 3x impossible because x is a natural number
If y=5 ⇒ 100 - 11×5 = 45 = 3x ⇒ x = 45/3 = 15
Then (x,y) = (15,5) is a solution to the equation
If y=4 ⇒ 100 - 11×4 = 56 = 3x impossible because x is a natural number
If y=3 ⇒ 100 - 11×3 = 67 = 3x impossible because x is a natural number
If y=2 ⇒ 100 - 11×2 = 78 = 3x ⇒ x = 78/3 = 26
Then (x,y) = (26,2) is a solution to the equation
If y=1 ⇒ 100 - 11×1 = 89 = 3x impossible because x is a natural number
If y=0 ⇒ 100 - 11×0 = 100 = 3x impossible because x is a natural number

x^2+11x+28/x^2+5x+4 simplify expression
Answers
Answer:
(x + 7)/(x + 1)
Step-by-step explanation:
Simplify the following:
(x^2 + 11 x + 28)/(x^2 + 5 x + 4)
The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):
(x^2 + 11 x + 28)/((x + 1) (x + 4))
The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):
((x + 4) (x + 7))/((x + 4) (x + 1))
((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):
Answer: (x + 7)/(x + 1)

Answer:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4 = x+7 / x+1
Step-by-step explanation:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4
1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)
2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)
** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals
3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1

A newly formed life insurance company has underwritten term policies on 120 women between the ages of forty and forty-four. Suppose that each woman has a 1/150 probability of dying during the next calendar year, and that each death requires the company to pay out $50,000 in benefits. Approximate the probability that the company will have to pay at least $150,000 in benefits next year
Answers
The probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
The probability of dying:
P(dying) = 1/150
P(living) = 1 - P(dying) = 1 - 1/150 = 140/150
There are 120 women.
P(x≥3) = 1 - [P(x=0) +P(x=1) + P(x=2)]
[tex]\rm P(x\geq 3)=1-[(120 \ choose \ 0)(1/150)^0)((149/150)^{120})+[/tex]
[tex]\rm (120 \ choose \ 1) ((1/150)^1) ((149/150)^{119}) +[/tex]
[tex]\rm (120 \ choose \ 2)((1/150)^2)((149/150)^{118})][/tex]
P(x≥3) = 0.047
Thus, the probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

The group wants to travel from its current location on the map to the South Pole, and then directly back to the base camp. How many miles will they have to travel? Explain your answer.
Answers
Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
First, the group travels 5 x 5 = 25 miles to the south pole.Then, the distance to the camp is the hypotenuse of a right triangle with sides of 25 miles and of 12 x 5 = 60 miles, hence:[tex]d^2 = 25^2 + 60^2[/tex]
[tex]d = \sqrt{25^2 + 60^2}[/tex]
d = 65.
The total distance is given by:
Td = 25 + 65 = 90 miles.

a tuba creates a 4th harmonic of frequency 116.5 hz what is the length of the pipe in the tuba
Answers
Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m
Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe
What is the frequency of an closed pipe?The frequency of a closed pipe f = nV/4L where
n = harmonic V = speed of sound and L = length of pipe in tubaLength of pipe in tubaMaking L subject of the formula, we have
L = nV/4f
Since the tuba creates the 4th harmonic with frequency 116.5 Hz.
n = 9 and f = 116.5 HzSubstituting the values of the variables into the equation, we have
L = nV/4f
L = 9 × 340 m/s/4 × 116.5 Hz
L = 3060 m/s ÷ 466 Hz
L = 6.57 m
So, the length of pipe in tuba is 6.57 m
