can you solve this pls 5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x
show step by step pls
Answer: x= -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−4)+3x−9x=6−(2x+5)+8x
(5)(x)+(5)(−4)+3x+−9x=6+−2x+−5+8x(Distribute)
5x+−20+3x+−9x=6+−2x+−5+8x
(5x+3x+−9x)+(−20)=(−2x+8x)+(6+−5)(Combine Like Terms)
−x+−20=6x+1
−x−20=6x+1
Step 2: Subtract 6x from both sides.
−x−20−6x=6x+1−6x
−7x−20=1
Step 3: Add 20 to both sides.
−7x−20+20=1+20
−7x=21
Step 4: Divide both sides by -7.
−7x

Jan completes 60 trials of pulling colored marbles out of a bag. She pulled green 15 times. If there are 250 marbles in the bag, how many of them are probably green?
Answer:
the answer is 63 green marbles
Step-by-step explanation:
Answer:
Green marbles are probably = 62.5.
Step-by-step explanation:
Since Jan completes 60 trials and pulled green 15 times, the probability of any marble being green can be calculated as:
= 15/60
= 0.25
With 250 marbles in the bag, using the probability value of green marbles calculated above, the number of green marbles can be estimated as:
= 0.25 of 250
= 62.5
This shows that since there is a 25% probability of obtaining a green marble from 60 trials of pulling colored marbles out of the bag containing 250 marbles, then the total number of green marbles will be equal to 62 or 63.
3a+2b+cx=2(4d-5e) how do i find x?
Answer:
[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]
Step-by-step explanation:
In order to find x, our goal is to isolate it on one side of the equation.
To do this, let's first apply the distributive property on the right side of the equation.
[tex]3a+2b+cx = 8d - 10e[/tex]
Now we can subtract [tex]3a[/tex] and [tex]2b[/tex] from both sides:
[tex]cx = 8d - 10e - 3a - 2b[/tex]
And now we can divide both sides by [tex]c[/tex] so that x is alone on the left side.
[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]
Hope this helped!

If you needed to buy at least 5 water bottles AND at least 8 water bottles, how many water bottles would you need to by?
Answer: You should get 15 water bottles
Step-by-step explanation: You need at least 8 water bottles and at least 5 water bottles so you should get 15 because 9+6.
The number of water bottles you would need to buy is at least 13 water bottles
At least means ≥ (greater than or equal to)let
b = water bottles
Statement 1:
at least 5 water bottles
b ≥ 5
statement 2:
at least 8 water bottles
b ≥ 8
The total number of water bottles you need to buy is at least 5 + 8b ≥ 13
Therefore, the number of water bottles you would need to buy is at least 13 water bottles

Evaluate the function Find f(x)= 3x^2-x+2 a. x=3 b. x=-5 c. f(2) d. f(m) e. f(x+2)
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 3x² - x + 2
To evaluate given values of x, substitute the values of x into f(x)
(a)
f(3) = 3(3)² - 3 + 2 = 3(9) - 1 = 27 - 1 = 26
(b)
f(- 5) = 3(- 5)² - (- 5) + 2 = 3(25) + 5 + 2 = 75 + 5 + 2 = 82
(c)
f(2) = 3(2)² - 2 + 2 = 3(4) = 12
(d)
f(m) = 3m² - m + 2
(d)
f(x + 2) = 3(x + 2)² - (x + 2) + 2 ← expand (x + 2)² using FOIL
= 3(x² + 4x + 4) - x - 2 + 2
= 3x² + 12x + 12 - x ← collect like terms
= 3x² + 11x + 12
A student throws a heavy ball downward off the top of a building with a speed of 18m/s. The ball reaches a speed of 41m/s just before striking the ground. Neglect drag.
Complete question:
A student throws a heavy ball downward off the top of a building with a speed of 18m/s. The ball reaches a speed of 41m/s just before striking the ground. Neglect drag, find the height of the building.
Answer:
The height of the building is 69.235 m
Step-by-step explanation:
Given;
initial velocity of the ball, u = 18 m/s
final velocity of the ball, v = 41 m/s
The height of the building is equal to distance traveled by the ball downward.
Apply the following kinematic equation;
v² = u² + 2gh
where;
g is acceleration due to gravity
h is height of the building
41² = 18² + 2(9.8)h
1681 = 324 + 19.6h
19.6h = 1681 - 324
19.6h = 1357
h = 1357 / 19.6
h = 69.235 m
Therefore, the height of the building is 69.235 m

Points Pand Q lie in plane A. How many lines contain P
and Q?
2. Lines PQ and QP
3. The 2 lines PQ and QP plus another line that does
not lie in plane A.
1. Line PQ
. We can't name them all!
Answer:
The correct answer is :
1. Line PQ (One line PQ).
Step-by-step explanation:
The first step to solve this question is to draw the plane A with the points P and Q lying on it.
We know that given two different points there is only one line that contains this two different points.
Let's analyze each option.
''2. Lines PQ and QP''
This option is wrong because there aren't two different lines. In fact it is only one line that can be named line PQ or line QP.
''3. The 2 lines PQ and QP plus another line that does not lie in plane A.''
This option is assuming that exist three lines that contain P and Q. This option is also wrong.
''1. Line PQ''
This option is correct. It will be clarify with the drawing I will attach.
''We can't name them all!''
This option is assuming that exist infinite lines that contain P and Q. This option is wrong.
In the drawing I call the line that contains P and Q as line L.
Given that P and Q lie in plane A necessarily the line L must lie on the plane A.
Only one line contains points P and Q
The given parameters are:
Plane APoints P and QThere are at least two points in a line
This means that, a line can contain points P and Q, and any other points
Hence, only one line contains points P and Q

What is wrong with the equation? π 4 sec(θ) tan(θ) dθ = 4 sec(θ) π π/3 = −12 π/3 There is nothing wrong with the equation. f(θ) = 4 sec(θ) tan(θ) is not continuous on the interval [π/3, π] so FTC2 cannot be applied. f(θ) = 4 tan(θ) is not continuous on the interval [π/3, π] so FTC2 cannot be applied. f(θ) = 4 sec(θ) is not continuous at θ = π/3 so FTC2 cannot be applied. The lower limit is not equal to 0, so FTC2 cannot be applied.
The given equation is not defined in the interval [tex]\left[\dfrac{\pi}{3},\pi\right][/tex]. Therefore, FTC2 is not applied and this can be determined by using the property of the trigonometric function.
Given :
Equation -- [tex]\rm \int^{\pi}_{\pi/3}7\;sec\theta\; tan\theta \;d\theta[/tex]
The following steps can be used in order to determine what is wrong with the given equation:
Step 1 - Write the given equation.
[tex]\rm \int^{\pi}_{\pi/3}7\;sec\theta\; tan\theta \;d\theta[/tex]
Step 2 - In the given equation [tex]\rm sec\theta[/tex] is not defined at [tex]\theta = \pi/2[/tex].
Step 3 - In the given equation [tex]\rm tan\theta[/tex] is not defined at [tex]\theta = \pi/2[/tex].
Step 4 - From the above steps, it can be concluded that the given equation is not defined in the interval [tex]\left[\dfrac{\pi}{3},\pi\right][/tex]. Therefore, FTC2 is not applied.

A choral conductor has 1542 singers in her choir, some of them are professional singers. The conductor wants to estimate what percentage of singers are professional, but can't ask all 1542, so she instead asks 650 singers in front and finds 19 who are professionals.
Answer:
The value is [tex]\r p = 2.9\%[/tex]
Step-by-step explanation:
From the question we are told that
The number of singers is [tex]N = 1542[/tex]
The sample size is [tex]n = 650[/tex]
The number the number of singers who are professional is k = 19
The proportion of professional singers is mathematically represented as
[tex]p = \frac{k}{n}[/tex]
=> [tex]p = \frac{19}{650}[/tex]
=> [tex]p = 0.029 [/tex]
The percentage estimate of singers who are professional is
[tex]\r p = 100 * 0.029[/tex]
[tex]\r p = 2.9\%[/tex]
