Answer:
The expression that can be used is 0.80x
Step-by-step explanation:
Let
x ----> original price of an item
Remember that
That means---> the sale price is 80% of the original price
To find out the sale price, determine the 80% of the original price
----> percentage in decimal form
Multiply the original price by the percentage in decimal form to obtain the sale price
so
Answer:
8(3j-2)
Step-by-step explanation:
Factor the following:
126 u + 28 v + 126
Factor 14 out of 126 u + 28 v + 126:
Answer: 14 (9 u + 2 v + 9)
Looking at the graph, we'll notice that there is a local maximum at x=0 and it looks similar on both sides of the y axis, therefore making it symmetric around the y axis given the options
A proportional relationship would look like y=mx (no y-intercept).
The formula for temperature Fahrenheit involves an offset (y-intercept); this is one reason I claim that the relationship in question is NOT proportional.
