Step-by-step explanation:
The square root of a number is any number that when multiplied against itself becomes the number under symbol denoting for the square root operation.
The number 10 is the result of the square root operator applied to the number 100 because 10 * 10 = 100.
The number 10 is a natural number because natural numbers are positive integers. It is also an integer, whole number, and rational.
Hope this answer helps!
Answer:
Ah yes, one of my favorite topics.
Step 1: Which ever fraction comes first, you will solve it first. For this question, focus on doing
first. Afterwards, do 
Step 2: First one equals to 1.125. Next, find the LCD (lowest common dominator, which is 10). 
Step 3: 1.125+3/10
To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y
Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250
Answer: the x-intercept is (-10,0), the y-intercept is (0,45/2)
Explanation:
First, we need to determine the function describing the line.
From the table, it is obvious that the y values increase by 9 every increase of 4 of the x values. So, the slope is 9/4 and the function looks like this:

with the y-intercept (or bias) b still unknown. This can be determined by using one of the point from the table, like so:

The above function form makes it easy to read off the y-intercept, which is (0,45/2) or (0,22.5). The x-intercept is obtained by setting y = 0 and solving for x:

The x-intercept is (-10,0)
