Answer:
y = 6x+ 3.
Step-by-step explanation:
y - y1 = m(x - x1)
sub.
distribute.
bring down and solve.
since a square must be the same length on all sides to be a correct square, you can legit just multiply the length of one side times four to get the area.
3.2 x 4 = 12.6
Answer:
Numbers greater than 4 are 5 and 6
So we have 2 numbers out of 6 numbers so the probability is equal to 2/6 = 1/3
And 1/3 of 12 is equal to 4
So Brian expect to roll a number greater than 4,
Four times.
Answer: Ix - 5I ≥ 5.
Step-by-step explanation:
We want the set:
[0, 10]
to be the solution of:
Ix - bI ≤ c
So we need to find the values of c and b.
The first step is to find the middle point in our segment.
We can do that by adding the extremes and dividing it by 2.
M = (10 + 0)/2 = 5
And we also want to find half of the difference between the extremes, this is:
D = (10 - 0)/2 = 5.
Now, this set will be the set of solutions of:
Ix - MI ≥ D
Then in our case, we have:
Ix - 5I ≥ 5.
so we have that b = 5, and c = 5.
