Answer:
The domain is y > 3
Step-by-step explanation:
y = 2⁻ˣ + 3
As x approaches -∞, y approaches ∞.
As x approaches ∞, y approaches 3.
So the range is y > 3, and there is an asymptote at y = 3.
Compared to the parent function y = 2ˣ, it is reflected over the y-axis and shifted up 3 units.
The false statement is "the domain is y > 3". Domain describes the possible values of x. Range describes the possible values of y.
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
These given angles are vertically opposite which means their measure is equal. Let's find x with the help of the equation..~
Move the constant to the right-hand side and change its sign
Add the numbers
Divide both sides of equation by 3
24 markers for $1.20 has a unit price of 5c per marker. 36 markers for $1.79 has a unit price of 4.97c so brand b is better value.
Answer:
18 posters
Step-by-step explanation:
Posters posted last week: 81/3 = 27 posters
Remaining posters: 81-27 = 54 posters
Posters posted this week: 54/3 = 18*2 = 36 posters
Posters remaining: 54-36 = 18 posters
