Step-by-step explanation:
x3(−5x+4)+5x−1=−39
−5x4+4x3+5x−1=−39
Step 1: Subtract -39 from both sides.
−5x4+4x3+5x−1−(−39)=−39−(−39)
−5x4+4x3+5x+38=0
Step 2: Factor left side of equation.
(−x+2)(5x3+6x2+12x+19)=0
Step 3: Set factors equal to 0.

x = 17 degrees
Solve 56 - 10x>20 + 8x.

B. X<-2
C. x >2
D. x<2
Answers
Answer:
x<2
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
56 - 10x > 20 + 8x ( add 10x to both sides )
56 > 20 + 18x ( subtract 20 from both sides )
36 > 18x ( divide both sides by 18 )
2 > x , thus
x < 2 → D
Ms. Reynold's sprinkler system has 3 stations that water all parts of her front and back lawn. Each station runs for an equal amount of time. If it takes 14 minutes for the first 2 stations to water, how long does it take to water all parts of her lawn?
Answers
Answer:
21 minutes
Step-by-step explanation:
Given that :
Sprinkler has 3 stations
Each waters for an equal amount of time ;
First 2 stations water for 14 minutes
Time taken per station :
14 / 2 = 7 minutes
Time taken to water all part of her lawn :
Time taken per station * number of stations
7 minutes * 3 = 21 minutes

Can someone help me with 13,14,15 and 16 please
Answers
Answer: -3/5, 18/32, -10/11, and horizontal.
Step-by-step explanation: Remember the equation for slope? Δy (the change in y), over Δx (the change in x). In other words, rise over run. To solve for Δ, you'd have to subtract the second output (y²) from the first (y¹). There are really no rules as to which has to be minuend and the subtrahend, so I chose to subtract (-1,6) from (4,3) for the first problem.
y¹-y² Δy 3-6 -3
------ or ---- so ------- = ----- The slope is represented by -3/5x
x¹-x² Δx 4-(-1) 5
__________________________________________________________
For the second, substitute the values again (make sure you keep the xs and ys together and in the right order, otherwise your answer will be incorrect). Remember that subtracting a negative number is basically just adding a positive number. That's why the slope is 18/32 and not 4/26.
11-(-7) 18
--------- = -------
29-(-3) 32
___________________________________________________________
For number three, they give you a point, then tell you the y-intercept. With that in mind, also know the second point is (0,17), because the x value at the y-intercept is always 0.
7-17 -10
------ = ------- The slope is -10/11x
11-0 11
___________________________________________________________
4-4 0
------ = --------
6-(-9) 15
Because there is no Δy, but there is Δx, we know that the line for y will be straight and shows no change- it will always be at 4. That said, the line will be horizontal.
I hope this helps. I know this is very confusing at first, but with practice, you'll eventually get the hang of it. I've tried to explain the rules to the best of my ability- let me know if there's anything you don't understand or need more help with.
Sincerely,

By the rational roots theorem, any rational zeros of the given cubic are expressible in the form
p
q
for integers
p
,
q
with
p
a divisor of the constant term
72
and
q
a divisor of the coefficient

of the leading term.
That means that the only possible rational zeros are:

In addition, note that all of the coefficients are positive and the constant term is non-zero. As a result, any real zero (rational or otherwise) of this cubic must be negative.
So that leaves rational possibilities:

An insurance company charges Ted $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answers
Answer:
The insurance company can expect to make $900 on the policy
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence [tex]{}[/tex] Probability Value v × p
A claim is made [tex]{}[/tex] 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim [tex]{}[/tex] 0.9 [tex]{}[/tex] $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900

4. 13 students like neither
Answers
Hi, you've asked an incomplete question. Here are the remaining questions:
a) Describe what each region in the Venn diagram represents.
Region I: In drama club, not in step team.
Region II: In both clubs.
Region III: In step team not in drama.
Region IV: Not in either club.
b) How many students were in only one of the two clubs?
c) How many students were in the drama club or in the step team?
d) How many students were surveyed?
Attached is the Venn diagram depicting the regions.
Explanation:
b) By adding the number of students that like drama club and those that like step club we can derive the answer: 34 + 27 = 61.
c) By adding 34 + 27 + those that like both (14) = 75.
d) The total number of students surveyed is gotten by summing any number in attached the diagram: 34 + 27 + 14 + 13 = 88.
a bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 8 feet per second. It is away frim the hive for a total of 16 minutes. what equation can can you use to find the distance of the flowerbed from the hive? How far is the flowerbed from the hive?
Answers
Answer:
(x/12 + 840 + x/8) = 960
576 feets
Step-by-step explanation:
Given that :
Speed to flower bed = 12 ft/s
Speed back to hive = 8 ft/s
Time spent at flower bed = 14 minutes = 14*60.= 840
Total time = 16 mins = (16 * 60) = 960
Let distance between bee hive and flower bed = x
Time taken to flower bed = x / 12
Time taken back to hive = x /8
(x/12 + 840 + x/8) = 960 - - equation
L.C.M of 12 and 8 = 24
(2x + 20160 + 3x)/ 24 = 960
(2x + 20160 + 3x) = 23040
5x = 23040 - 20160
5x = 2880
x = 2880 / 5
x = 576
Distance between flowerbed and hive = 576 feets
