Infinite sets may be countable or uncountable. Some examples are: the set of all integers, {..., -1, 0, 1, 2, ...}, is a countably infinite set; and. the set of all real numbers is an uncountably infinite set.
Answer:
60.444
Step-by-step explanation:
Answer:
d) 87
Step-by-step explanation:
to solve this lets set up the equation
then we multiply 4 on both sides
253+x=340
and subtract 253 on both sides
x=87
to double check take the averages
(87+85+70+98)/4=85
Answer:
x = 4
Step-by-step explanation:
Given
5(2x - 1) = 35 ( divide both sides by 5 )
2x - 1 = 7 ( add 1 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
0
Step-by-step explanation:
y = f(x)
f(x) = - 3
y = -3 (Substitution)
From the graph, the line reaches the y-axis at -3. As you can see the x-axis is 0. So if f(x) = -3, then x = 0
