Step-by-step explanation:
Rational expressions are in the form of
Here from the definition it is very important to know that the denominator of a rational expression is never zero.
If the denominator is zero then it becomes undefined.
Let us take an example of a rational expression.
This is a rational expression and it is defined only when
It means that the expression is defined for all real values of x except x =-2
If he carried the ball 16 times, how many yards did he gain (y)?
A.
y = 4 + 16
B.
y = 4 • 16
C.
y = 16 ÷ 4
D.
y = 4 ÷ 16
Answer:
20 ≤ L + W ≤ 40
Step-by-step explanation:
[answer is marked by ** symbol]
The perimeter (P) of a rectangle is given by the formula:
P = 2L + 2W
In this case, you want to spend between $100 and $200 on fencing, and the cost is $2.50 per foot. So, you can write the cost equation as:
Cost = 2.50 (2L + 2W)
Now, you want the cost to be between $100 and $200, which leads to a compound inequality:
$100 ≤ 2.50 (2L + 2W) ≤ $200
Now, divide each part of the compound inequality by 2.50 to isolate the expression (2L + 2W):
$100 / 2.50 ≤ 2L + 2W ≤ $200 / 2.50
40 ≤ 2L + 2W ≤ 80
Now, divide each part by 2 to find L + W:
**20 ≤ L + W ≤ 40
**This compound inequality models the possible length of the dog run. It states that the length plus the width of the dog run must be between 20 feet and 40 feet to stay within the budget of $100 to $200 for fencing.
But at the end it says you should include this info… Choose two sets of data (x and y values). Calculate the difference between the two y values. Calculate the difference between the corresponding two x values. Slope is the difference in y values / difference in x values.
Use this information to your advantage.
Hope this helps! :))
Answer:
Take two pairs for example (1,1) and (2,2) and then put y coordinates over x coordinates in like a fraction and then subtract them. Once the y coordinate have been subtracted from each other and the x coordinates have been subtracted from each other then divide the top from the bottom.
