225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.
Answer:
The number 15 is the median..
I wish i knew this answer to help you. i really hope u find it
Part A
The graph passes through .
If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points.
Using and .
We obtain the slope to be
Using and .
We obtain the slope to be
.
Since the slope is not constant(the same) everywhere, the function is non-linear.
Part B
A linear function is of the form
where is the slope and is the y-intercept.
An example is
A linear function can also be of the form,
where and are constants.
An example is
A non linear function contains at least one of the following,
- Product of and
- Trigonometric function
- Exponential functions
- Logarithmic functions
- A degree which is not equal to or .
An example is or or etc
Answer:
the graph would cut the y-axis 11 units below y=f(x)
