Answer: C
Step-by-step explanation: If B is the set of colleges that have a physics department.
B’ is the set of colleges that do not have a physics department.
U is the union, so we are going to put every element from A and B' together. It can be translated as OR.
A U B’ is the set of elements in a country that have a hockey team (A) or do not have a physics department (B’)

Answer:
y-4=-7(x-3) and y=-3/8x-8
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
the slope is already -7.
We can the just plug in the values: y-4=-7(x-3)
For the 2nd problem we can plug in values as well: -2=3/8(16)+b.
-2=6+b. the y intercept is -8. The final form is y=-3/8x-8
hi!
its not a function since it has a =5
this is an equation
Answer: 21, 23, 25
Step-by-step explanation:
Let the integers be y, y+2 and y+4.
From the question, we are informed that the result of adding the smallest integer to four times the largest integer is 121. This can be mathematically expressed as:
y + 4(y+4) = 121
y + 4y + 16 = 121
5y + 16 = 121
5y = 121-16
5y = 105
y = 105/5
y = 21
Since y = 21,
y + 2 = 21 + 2 = 23
y + 4 = 21 + 4 = 25
The integers are 21,23 and 25
