2. Which equation has no solution? *
1 poir
O x-5(x + 4) = 2(2x + 7) + 6
O 5(x + 1) - 3x = 5 - 2(5 - x)
O 1 - 3(x + 3) = 2(3x – 4) - 9x
O 3(x - 4) + x = 4(3 - x)
Answer:
5(x+1) - 3x = 5 - 2(5-x)
Step-by-step explanation:
This has no solution. Explanation:
5(x+1) - 3x = 5 - 2(5-x)
5x + 5 - 3x = 5 -10 + 2x
2x + 5 = -5 + 2x
5 = -5
From the result above, clearly there is no x to satisfy the equation, because 5 (to the left) can never be the same as -5 (to the right).
Subtract fifteen and eighty-eight ten-thousandths from thirty-six. Express your answer in numerical and word form.
Answer:
20 and nine thousand nine hundred and twelve ten thousandth
Step-by-step explanation:
fifteen and eighty-eight ten thousandth =15 88/10000
Thirty six=36
36 - 15 88/10000
36 - 150088/10000
(36x10000 - 150088)/10000
(360000 - 150088)/10000
209912/10000=20 9912/10000
20 and nine thousand,nine hundred and twelve ten thousandth
The value of the expression [36 - (15 + 88 / 10,000)] is 20.9912.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Subtract fifteen and eighty-eight ten-thousandths from thirty-six. Then the expression is given as,
⇒ 36 - (15 + 88 / 10,000)
The value of the expression is calculated as,
⇒ 36 - (15 + 88 / 10,000)
⇒ 36 - (150,088/10,000)
⇒ (360,000 - 150,088) / 10,000
⇒ 209,912 / 10,000
⇒ 20.9912

There are 20 peoples in a singing group. The mean age of 12 of the members is 18years. The mean age of the remaining 8 is 23 years. What is the mean age of the 20 members of the singing group?
Answer:
20
Step-by-step explanation:
The sum of the ages of the first 12 is ...
12×18 = 216
The sum of the ages of the remaining 8 is ...
8×23 = 184
So, the sum of ages of all 20 people is ...
216 +184 = 400
and their average age is ...
400/20 = 20
The mean age of the members of the group is 20.

what is the sum of 21 and 5 times a number f is 61
Answer:
f = 8
Step-by-step explanation:
21 + 5f = 61
5f = 61 - 21
f = (61 - 21) / 5
f = 8
Answer:
f = 8
Step-by-step explanation:
"Sum" = addition
"Times" = multiplication
Write an equation to represent this scenario
21 + 5 * f = 61
Multiply 5 by f
21 + 5f = 61
Subtract 21 from both sides of the equation
5f = 40
Divide both sides of the equation by 5
f = 8

(40, 96)
(85, 105)
(80, 104)
(96, 72)
Answer:
the answer is (40,96)
Step-by-step explanation:
Point P on the directed line segment from K to J has x and y coordinates that are three-fifths of the length of the line segment from K to J
(85, 105).
What are coordinates?The coordinates point to any point can be found by using the following formula.
X = [m/(m + n)](x₂ - x₁) + x₁
Y = [m/(m + n)](y₂ - y₁) + y₁
Given, On a coordinate plane, a line is drawn from point K to point J. Point K is at (160, 120) and point J is at (negative 40, 80).
The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is;
X = [m/(m + n)](x₂ - x₁) + x₁
X = [3/(3 + 5)](- 40 - 160) + 160.
X = - 75 + 160.
X = 85.
Y = [m/(m + n)](y₂ - y₁) + y₁
Y = [3/(3 + 5)](80 - 120) + 120.
Y = - 15 + 120.
Y = 105
As a result, point P's x and y coordinates are such that P is three-fifths the length of the directed line segment from K to J (85, 105).

What is the slope of a line that is parallel to the line
represented by the equation y- 4x = 1?
Answer:
m=4
Step-by-step explanation:
First get the equation in slope intercept form
y -4x =1
Add 4x to each side
y - 4x+4x = 4x+1
y = 4x+1
This is in the form
y = mx+b where m is the slope and b is the y intercept
The slope is 4
Parallel lines have the same slope
m =4

Tyson wants to buy some juice pouches. He has four options to choose from.
Which option has the lowest cost per pouch?
O A 8 pouches for $2.04
O B 10 pouches for $2.69
O C 12 pouches for $2.80
O D 16 pouches for $3.80
Explanation:
x = number of pouches
y = cost for having x number of pouches
To find the unit cost, divide y over x
For choices A through D we have the following unit costs
y/x = 2.04/8 = 0.255y/x = 2.69/10 = 0.269y/x = 2.80/12 = 0.233 (approximately)y/x = 3.80/16 = 0.2375We see that 0.233 is the lowest unit cost, so therefore, Choice C is the lowest cost per pouch.

Assume the average weight of an American adult male is 180 pounds with a standard deviation of 34 pounds. The distribution of weights follows a normal distribution. What is the probability that a man weighs somewhere between 120 and 155 pounds?
Answer:
Step-by-step explanation:
Find a-score of both
z-score = (x-mean)/SD
for 120
z =( 120- 180)/34 = -1.765
For 155
z = (155-180)/34 = -0.735
The probability to look for using z-score table is;
P(-1.765<z<-0.735) = 0.19239
A TV station is going to air a movie marathon with 8 movies. It will consist of 2 science fiction movies and 6 horror movies. The horror movies will be aired later in the evening. So, all of the horror movies will be aired last (after both of the science fiction movies). In how many ways can the station air the movie marathon?
Answer:
Total ways to run movies = 1,440
Step-by-step explanation:
Given:
Number of total movies = 8
Number of science fiction movie = 2
Number of horror fiction movie = 6
Find:
Total ways to run movies.
Computation:
Number of science fiction movies way air = 2!
Number of science fiction movies way air = 2×1
Number of science fiction movies way air = 2
Number of horror fiction movies way air = 6!
Number of science fiction movies way air = 6×5×4×3×2×1
Number of science fiction movies way air = 720
Total ways to run movies = 2 × 720
Total ways to run movies = 1,440

In the interval 0 degrees < x < 360 degrees, find the values of x for which cos x =-0.4226
Give your answers to the nearest degree.
Answer:
The value of x within the interval are 115° and 245°Step-by-step explanation:
Given the trigonometric equation;
cos x =-0.4226
To get the value of x within the range 0° < x < 360°, we need to take the arc cosine of the value as shown;
x = arccos -0.4226
x = 114.99°
x ≈ 115°
Since x is positive in the 4th quadrant, the value of x can also be 360 - [tex]\theta[/tex]
where [tex]\theta = 115^{o}[/tex]
x2 = 360°-115°

Answer:
(-8, infinity)
Step-by-step explanation:
it's the first option on edge
The solution is, : The given function f(x) is decreasing on the interval :
(-8, +∞).
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
The function is given to be : f(x) = (x + 8)² - 1
To find the interval of decreasing, first find the critical points of the function f(x)
f(x) = (x + 8)² - 1
⇒ f'(x) = 2(x + 8)
Critical Point : x = -8
Now, Intervals are : (-∞ , -8) and (-8, +∞)
For the interval : (-∞ , -8)
f'(x) > 0 ⇒ f(x) is increasing on this interval.
For the interval : (-8, +∞)
f'(x) < 0 ⇒ f(x) is decreasing on this interval.
Hence, The given function f(x) is decreasing on the interval : (-8, +∞).

What are the area and parameters of a rectangle?The region that a rectangle occupies in a two-dimensional space is referred to as the area of a rectangle. The quantity of square units required to entirely fill a rectangle is another way to describe its area. The whole distance encircling a rectangle's outside is referred to as its perimeter.
Given, A rectangular animal pen will be built using 200 meters of fencing. If one side of the fence is 60 meters. Hence,
Parameter of rectangle = 200
2(length + width ) = 200
given length of the pen is 60 meters
2(60 + width) = 200
width = 100- 60 = 40
Area of the rectangle = length * width = 60* 40 = 2400
Therefore, 2400 square meters will be the area of the given rectangular pen.
