Answer:
Step-by-step explanation:
a) -1, 1, 5
b) -3
c) -1 to 6
d) -3 to 2
e) for a value, we need an input between or equal to -1 to 6, what ever that x value is, find it on the graph, then see what the y value is at that point. That's your value of f
Subtract
$72 - $60 = $12
$12 profit
You then put the profit increase OVER the original price, making it a fraction. 12/60 now if you simplify this it is 1/5.
1/5 into a decimal is .20 and .20 to percentage is .20 x 100 = 20%
You can turn fractions to a decimal by diving the numerator by denominator. Just think of the line as the word DIVIDE.
Answer: 20% increase
The correct answer is -x+4
Answer:
9/49
Step-by-step explanation:
4 purple beads and 3 green beads= 7 beads
P( green) = green = total = 3/7
Replace the bead
4 purple beads and 3 green beads= 7 beads
P( green) = green = total = 3/7
P( green , replace, green) = 3/7 * 3/7 = 9/49
The answer would be D if it was 250-6-3n. it wouldnt be A or C because 9 isnt anywhere in the problem and it wouldnt be B because she used 6 peices of paper she didnt just give it to her students
