The rate of change is the same things as slope equation for slope is y2-y1 over x2-x1 4- (-6) is 10 -10 -0 is -10 so the answer would be -1
Okay, so there's 100 pennies in a dollar and 100 x 200 = 20,000
Then to find our amount of millimeters we need to do 20,000 x 1.55 = 31,000 millimeters = 31 meters
Hope it helps!
A real world example could be:
Consider x is time in minutes
Consider y is the amount of fish food required in grams
The equation could then represent how much food (in grams) that a fish needs to be fed x minutes after it was previously fed.
Answer:
72
Step-by-step explanation:
Given that:
P(Red) = Probability of randomly choosing a red
Probability of randomly choosing a red = 7/12
Number of red marbles = 42
The number of marbles in the bag :
P(Red) = number of red marbles / total number of marbles
Total number of marbles = (red marbles + blue marbles)
P(red) = 7/ 12 ;number of red = 42
P(Red) = number of red marbles / total number of marbles
Let:
x = total number of marbles
7/12 = 42 / x
(7/ 12)x = 42
7x / 12 = 42
7x = 12 * 42
7x = 504
x = 504 / 7
x = 72
