What is the median number for the numbers 4, 8, 10, 5, 9

1 answer:

7 0

The median number means the middle number. Before finding the middle number, you must line up the numbers from decreasing to increasing size:

4, 5, 8, 9, 10

Then, simply find the number in the middle. Since there are five numbers in this list, the middle number will be the third one: 8.

A car is worth $50,000 brand new and it will loose 10% of its value each year

notka56 [123]

We can set this geometric sequence up as so:

y = 50,000(0.90)^(x - 1)

The value of the car is represented by y, and the year is represented by x.

Find an equation for the line with slope m = -6/7 and which goes through the point (14, 4).

sammy [17]

Answer:

y = -6/7x + 16

Step-by-step explanation:

Use the slope intercept equation, y = mx + b

Plug in the slope and given point, then solve for b:

y = mx + b

4 = -6/7(14) + b

4 = -12 + b

16 = b

Plug in the slope and b into the equation:

y = mx + b

y = -6/7x + 16

So, the equation is y = -6/7x + 16

If f(x) = 2x + 1, and g(x) = x - 3, then f(g(x)) = [ ? ]x + [ ]

ad-work [718]

Answer:

First box +2

Second box -5

Step-by-step explanation:

Just an Example,

If f(x) = 2x + 1 and we need f(2) we would replace the x in the function with the number 2 because 2 is the domain of the function , so f(2) would become,

f(2) = 2(2) + 1

f(2) = 4 + 1 = 5

Now the question is what is f(g(x)) in this case the domain of the function is g(x). In simpler words we replace x with the function g(x) so here goes,

$f(x)=2x+1\\g(x)=x-3\\f(g(x))=2(x-3)+1\\f(g(x))=2x-6+1\\f(g(x))=2x-5$

so,

f(g(x)) = 2x - 5
