Answer:
2.50x+80>4.00
Step-by-step explanation:
The answer is number 1 since a function can't have x repeated. all the other ones have a single x giving 2 numbers. if this happens once it is no longer a function.
One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
Answer:
19 shows direct variation
20 does not (guessing for this one a bit)
19- Shows a steady increase of four in y for each one in x
20- Shows no increase
Step-by-step explanation:
19 is a constant increase by 4, 20 does not show either
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)
