2n+4=22
gimme the answer
Answer: n=9
Step-by-step explanation:
I'm assuming you want to solve for n, as that's the only possible question I can think of.
To solve for n, we want to isolate n by using inverse operations.
2n+4=22 [subtract both sides by 4]
2n=18 [divide both sides by 2]
n=9
Therefore, n=9 Is the answer.

The time taken to complete the rest questions is 32 minutes
Since Yan has already finished Three-fifths of the 45 math problems he was assigned today. The number remaining will be:
= 45 - (3/5 × 45)
= 45 - 27
= 18
Now, the time taken to complete the rest questions will be:
= 18 × 1 4/5
= 18 × 1.80

x^2+6x+8=0 complete the square method
Answer:
x = - 2 or x = - 4
Step-by-step explanation:
Via completing the square:
x^2 + 6x + 8 = x^2 + 6x + (6/2)^2 - (6/2)^2 + 8
= (x + 3)^2 - 3^2 + 8
= (x + 3)^2 - 9 + 8
= (x + 3)^2 - 1
Since x^2+6x+8=0,
(x + 3)^2 - 1 = 0
(x + 3)^2 = 1
x + 3 = +- sqrt(1)
x + 3 = +- 1
x + 3 = 1 or x + 3 = -1
x = -2 or x = -4

Answer:
(-1,0)
Step-by-step explanation:
To find the x value of the vertex use the equation
-b/(2a)
-4/(2*2)= -1
this means that the x coordinate is -1
Now that we know the x value we need to find the corresponding y value
to do this we just plug in x into the equation
2(-1)²+4(-1)+2
2-4+2=0
put it all together and get (-1,0)

If h(x) = f(x) - g(x) = 2x, at what x-value will f(x) = g(x) + 20?
a) x = 20
b) x = 10
c) x = 5
d) x = 2
Answer:
B
Step-by-step explanation:
This is a neat question
f(x) - g(x) = 2x Add g(x) to both sides
f(x) = g(x) + 2x
Now you need the right hand side to have 20 added to g(x).
2x must = 20
2x = 20 Divide by 2
x = 20/2
x = 10
So the answer must be x = 10

Answer:
A
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle , then
∠ B + 90° = 140° ( subtract 90° from both sides )
∠ B = 50°
∠ ACB and ∠ DCB are a linear pair and sum to 180° , that is
∠ ACB + 140° = 180° ( subtract 140° from both sides )
∠ ACB = 40°

Answer:
sin(T)
cos(C)
Step-by-step explanation:
sine goes up or down for angles in the circle.
cosine goes left or right for angles in the circle.
consider a circle with is center at T, and it goes through C (so, the radius is 25 = TC).
then 7 = sin(T)×25
24 = cos(T)×25
so, sin(T) = 7/25
then, sin(T) = cos(90-T)
and the angle at C = 90-T.
therefore, cos(C)=sin(T)=7/25
tan(x) = sin(x)/cos(x)
and that would lead here always to a 7/24 or 24/7 ratio.
so, no tan function is right.

Answer:
68, 97, 81, 96, 84.2
Step-by-step explanation:
16. The minimum of the data is the smallest value. Take the smallest stem value and find its smallest leaf value, you'll get 68.
17. Take the largest stem value and find its largest leaf value. That's 97.
18. Counting the number of values, there are 10 values here. So you need to look at the mean of the 5th and 6th values. (80 + 82) ÷ 2 = 81
19. Mode: the most frequently occurring value. All values in this dataset are unique except for the two 96s in the last row, hence 96 is the mode.
20. Add all values and divide your result by the number of values.
(68+75+77+79+80+82+92+96+96+97) ÷ 10 = 84.2
Hence 84.2 is your mean.

What is piecewise function?To fully understand what piecewise functions are and how we can construct our own piecewise-defined functions, let’s first dive into a deeper understanding of how it works.A piecewise function is a function that is defined by different formulas or functions for each given interval. It’s also in the name: piece. The function is defined by pieces of functions for each part of the domain.In mathematics, a piecewise-defined function is a function defined by multiple sub-functions, where each sub-function applies to a different interval in the domain. Piecewise definition is actually a way of expressing the function, rather than a characteristic of the function itself.To learn more about piecewise function refer to:

An object is moving at a speed of 11 yards every 6 months. Express this speed in centimeters per hour.
Speed of the given object in centimeters per hour
= 0.23 cm / hour
What is unit conversion?Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters.
Like 1 yard = 91.44 cm
1 month = 730 hrs.
Distance covered by the object = 11 yards
Distance covered in cm = 11 × 91.44 = 1005.84 cm
Time taken to cover 11 yards = 6 months
Time taken in hours = 6 × 730 = 4380 hrs.
Speed of the object = distance covered by the object / Time taken
Speed of the object = 1005.84/4380 = 0.2296 ≈ 0.23 cm per hour
Hence, in centimeters per hour,
the speed of the object is 0.23 cm / hour.

What is Unitary Method?The unitary technique involves first determining the value of a single unit,
followed by the value of the necessary number of units.
For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A company spent 762500 to make a movie.
The total movie will be earned
= 762500 + 2000000
= 2,762,500
First week the movie earned 1, 250,000.
So, in 7 weeks the movie needs to earned

Given the graph of this function, determine the statement that best describes the end behavior.
x->∞,y->∞ and as x-> - ∞ , y-> - ∞ this statement best describes the end behavior.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
First, we need to analyze the plotting of the graph. When it is on the negative axis of x, as the values of x increase (x values increasing in the negative axis means it's decreasing in value), the y values also increase. So as x decreases, y increases.
On the positive axis of x, as the x values increase, the corresponding values of y also increase with x. So as x increases, y values also increase with it.
Hence, x->∞,y->∞ and as x-> - ∞ , y-> - ∞ this statement best describes the end behavior.

action figures.
Write an equation that can be used to find x, the number of action
figures per person.
Answer:
x = 22 (each friend started with 22 action figures)
Step-by-step explanation:
After buying 8 more action figures, each friend has x + 8 action figures. Because there are 5 friends, the new total number of action figures is 5(x + 8), which we are told is equal to 150. Dividing both sides of this equation by 5 yields x + 8 = 30, and subtracting 8 from both sides yields x = 22.
