For the first triangle add 45 and 95 and subtract it from 180
Answer:
(Change in y)/(change in x) is defined as the average rate of change.
For a linear equation:
y = a*x + b
A is the average rate of change, and is called the "slope" of the linear equation, and this is a constant.
Then the sentence will be:
"The average change between two ordered pairs (x,y) is the ratio (change in x)/(change in y)
In a linear function, this is called the slope, and it is constant"

Determine her savings.



Solving (a):


Required
Determine the price before tax
First, we need to determine her savings



The price before tax is calculated as follows:


The expression is 2 x3 + 7 =13
Answer: The answer would be B. 
Because we know that she bought 6 bags of 36 jewels. So the first part we would need to solve would be the total number of jewel she purchased. Which would be
. Then, you must find the total number of jewels that she used. Which would be
. This means that the equaltion would be the total number of jewels-the total numnber of jewels used. Aka:
