Can the sum of two irrational numbers ever be a rational number? Can the quotient of two irrational numbers ever be a rational number
Answer:
Yes and yes
Step-by-step explanation:
Example:
√2, 1 + √2 and 1 - √2 are all irrational.
(1 + √2) + (1 - √2) = 2
The irrational numbers cancel out, leaving you with 1 + 1 = 2, which is rational.
For quotients, we'll use √2 again.
√2/√2 = 1
1 is rational
Find the inverse of the following
F(x)=-3/4x+6
Answer:
[tex] {f}^{ - 1} (x)= - \frac{4}{3} x + 8[/tex]
Step-by-step explanation:
[tex]f(x) = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6[/tex]
[tex]x = - \frac{3}{4} y + 6[/tex]
[tex] - \frac{3}{4} y + 6 = x[/tex]
[tex] - 3y + 24 = 4x[/tex]
[tex] - 3y = 4x - 24[/tex]
[tex]\boxed{\green{ {f}^{ - 1} (x)= - \frac{4}{3} x + 8}}[/tex]

Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
09. Find the value of x according to the data given in the diagram.
Answer:
x = 50°
Step-by-step explanation:
The lower right angle in the triangle = 40° ( alternate angle )
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x , that is
x = 180° - (90 + 40)° = 180° - 130° = 50°
Let f(x) = 5x + x2 and g(x) = 3x2 - 4x. Find f(x) * g(x)
Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
[tex]\large \mathfrak{Solution : }[/tex]
f (x) = x² + 5x
g (x) = 3x² - 4x
f (x) * g (x) :

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last skater. Then, they try to decide whether or not Oliver should be the first skater in the race.
Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?
A = {MOPN, PMON}
A = {OPMN, OMPN}
A = {MOPN, MPON, OPMN, POMN}
A = {MOPN, MPON, PMON, POMN}
Answer:
A = {OPMN, OMPN}
Step-by-step explanation:
If Olivers first and Naims last that's the only one that fits
Hope this helps, please leave any questions or concerns in the comments. Thanks
A = {MOPN, PMON} is the subset of the sample space shows the complement of the event in which Oliver is the first skater in the race
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The sample space of the relay race is the set of all possible arrangements of the four skaters, which can be represented by the permutations of the set {M, N, O, P}.
Since Naim is the last skater, there are 3! = 6 possible arrangements of the other skaters in front of him.
The event in which Oliver is the first skater in the race can be represented by the set {OMPN, OPNM, ONPM, ONMP}, which contains 4 possible arrangements.
The complement of this event is the set of all arrangements where Oliver is not the first skater, which can be represented by the set A.
Since there are 6 possible arrangements and 4 of them have Oliver in the first position, there are 6 - 4 = 2 arrangements in A.
A = {MOPN, PMON} is the complement
Hence, A = {MOPN, PMON} is the subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race

y is directly proportional to √X
When x = 49, y = 4
(Not from the question, remember that this "When x = 49, y = 4," is to find K)
a) Find a formula for y in terms of x.
Workout:
Step 1:
Y= k√X
4= k √49
4= k (7) (Here the 7 is in multiplication, now we'll divide it meaning 4/7)
4/7= K
Step 2:
To find the formula:
y= 4/7 √X (Final relation)
Answer for a) y= 4/7 √x
Answer: y = 4/7 √x

Eduardo cycled a total of 12 kilometers by making 3 trips to work. How many trips will
Eduardo have to make to cycle a total of 28 kilometers? Solve using unit rates.
trips
Submit
Answer:
12 trips
Step-by-step explanation:
Eduardo cycles 12 kilometers per 3 trips
The unit rate would be 4 kilometers per 1 trip, because you divide each side by 3.
You can figure out that 28 divided by 7 equals 4. So, you can multiply the number of trips by 4
(3 x 4) equals 12
So, Eduardo takes 12 trips to cycle 28 kilometers
