Answer:
2
Step-by-step explanation:
divide both sides by 4, so that y is alone
Answer:
Our expression is 205+2d where d is days past 60.
Step-by-step explanation:
Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.
205
Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:
205+2
Day 62 will be:
205 +2+2
Notice, that for two days past 60, the sunflower has grown 2 times as much.
Our expression is 205+2d where d is days past 60.
Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
- it is shifted downwards by 8 units
- it is not shifted to the left or the right
Therefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is shifted to the left 7 units
Therefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
- it is shifted upwards by 4 units
- it is shifted to right by 5 units
Therefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is not shifted to right by 12 units
Therefore D(x) = f(x - 12)
When the x-differences are all constant, then the y-differences (or first differences) are useful in telling if a set of data is nearly linear or not.
Answer:
73/80
Step-by-step explanation:
multiples of 11 between 1 and 80 are 11,22,33,44,55,66,77
number of terms=7
P(multiple of 11)=7/80
P(not a multiple of 11)=1-7/80=73/80
