Find the median and mode of 14 ,25, 14, 28, 18, 17, 18, 14, 23 22, 14 and 18
Answers
Answer:
Ascending order - 14, 14, 14, 14, 17, 18, 18, 22,
23, 25, 28
Median = ( n+1/2)
= ( 11+1/2)
= 12/2 = 6th term
Here, in order 6th term is 18, so 18 is median.
Mode is frequently occurring number.
Here frequently occurring number is 14 i,e 4 times.
Hence, 14 is mode.
Answer:

3. Determine the value of x if:
3.1. 75x -15 =5x + 125
3.2. 6(3x - 2) = 7(x + 3) +2
3.3.10/x-3= 8
3.4. x + 7 = 5x - 13
3.5. 20x +4 =4x - 46
Answers
Step-by-step explanation:
3.1.
your question
75x-25=5x+125
collect like terms
70x=150
Divide both side by the coefficient of x
70x/70=150/70
70 ti cancel 70 on x side to leave x alone
:. x=150/70 or 2.14
3.2.
6×(3x-2)=7×(x+3)
multiply by the bracket
18x-12=7x+21
collect like terms
18x+7x=21+12
25x=33
divide by the coefficient of x
25x/25=33/25
x=33/25 or 1.32
3.3.
10/x-3=8
cross multiply(know that 8 is /1)
x‐3×8=10×1
8x-24=10
8x=10+24
8x=34
divide both sides by coefficient of x
8x/8=34/8
8x=34/8 or 4.25
3.4.
x+7=5x-13
collect like terms
7+13=5x-x
20=4x
divide both sides by the coefficient of x
20/4=4x/4
5=x
:.x=5
3.5.
20x+4=4x-46
collect like terms
20x-4x=-46-4
16x=-52
divide both sides by the coefficient of x
16x/16=-52/16
:.x=52/16 or 3.25
Factor this polynomial completely.

Answer:10 times
Step-by-step explanation:
The value of 7 in 70,048 stands for 7 Ten thousand which is equal to 70,000
Also 7 in 17,992 stands for 7 thousand which is equal to 7,000
So we divide to know how much the lesser value is in the grater vale giving us
70,000/7,000 =10
Therefore, the value of 7 in 70,048 is 10 times than the value of 7 in 17,992

How would I graph y = 5/3 x -9
Answers
The y intercept shows there should be a point at (0, -9) on the y axis.
From that point you can use the slope and go up 5 and over to the right 3 before plotting the next point. You can keep doing that in that direction and you can also go in the reverse by going down 5 and to the left 3 if necessary in the graph.
In the end it would look like this.

If two functions, f(x) and g(x), are inverse functions, what must the composition of f(g(x)) and g(f(x)) both equal?
A. 0
B. 1
C. f(x) = g(x)
D. x
Answers
==========================================================
Explanation:
The composition of the original function with its inverse will cancel out the operations to yield the input as the output.
Consider the example functions shown below
f(x) = x+5g(x) = x-5The first function adds 5 while the second function does the complete opposite and subtract 5. The two functions are inverses of each other.
We see that,
f(x) = x+5
f(g(x)) = g(x)+5
f(g(x)) = x-5+5
f(g(x)) = x
and you should find that g(f(x)) = x for similar steps.
No matter what the x input is, the output will be identical to the input.
For instance, if we plug in x = 7, then adding 5 to it gets us 12. Then undoing that operation to subtract 5 gets us back to 7 again. This is one example showing why both f(g(x)) and g(f(x)) both equal x, where f and g are inverses of each other.

- a positive slope will be an increasing line (an uphill line)
- a negotiate slope will be a decreasing line (a downhill line)
- a zero slope will be a flat line (no incline or decline)
- an undefined slope fits with a line that doesn’t go left-to-right. It’ll be a vertical line.
For line 1 slope is negative, for line 2 slope is undefined, for line 3 slope is positive and for line 4 slope is zero.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The slope of a line is a measure of its steepness and direction. To determine the sign of the slope, we need to look at the direction of the line:
If the line is slanting upwards from left to right, the slope is positive.If the line is slanting downwards from left to right, the slope is negative.If the line is vertical, the slope is undefined (since the denominator of the slope formula, which is the difference in x-coordinates, is zero).If the line is horizontal, the slope is zero (since the numerator of the slope formula, which is the difference in y-coordinates, is zero).Therefore, Lines 1, 2, and 4 have negative slopes, undefinable slopes for lines 2 and 3, and positive slopes for lines 3 and zero for lines 4.
