Answer:
Step-by-step explanation:
We are given that a and b are rational numbers where
and x is irrational number .
We have to prove a+bx is irrational number by contradiction.
Supposition:let a+bx is a rational number then it can be written in
form
where
where p and q are integers.
Proof:
After dividing p and q by common factor except 1 then we get

r and s are coprime therefore, there is no common factor of r and s except 1.
where r and s are integers.


When we subtract one rational from other rational number then we get again a rational number and we divide one rational by other rational number then we get quotient number which is also rational.
Therefore, the number on the right hand of equal to is rational number but x is a irrational number .A rational number is not equal to an irrational number .Therefore, it is contradict by taking a+bx is a rational number .Hence, a+bx is an irrational number.
Conclusion: a+bx is an irrational number.
Answer: C
Step-by-step explanation: 3x and 5x both have x
No there are 96 inches in 8 feet because,
12 inches = 1 foot
12 x 8 = 96
so there are 96 inchs in 8 feet
The number "R" could be "A" and "D" because the range is 14 it cant be "B" or "C"
Standard form is Ax + By = C
y = (-3/4)x - 2
Multiply both sides by 4.
4y = -3x - 8
Add 3x on both sides
3x + 4y = -8
Your final answer is 3x + 4y = -8.
