Heya friend,

Let the digits at ones place be x. Then,
the digits at tens place = (8-x)
Original number = 10(8-x) + x
= 80 - 10x + x
= 80 - 9x
On interchanging the digits
new number obtained = 10x + 8-x
= 9x + 8
According to question,
New number - Original number = 18
9x + 8 - (80-9x) = 18
=> 9x + 8 - 80 + 9x = 18
=> 18x - 72 = 18
=> 18x = 18 + 72
=> 18x = 90
=> x = 90/18
=> x = 5
Hence, the digits at ones place is 5.
The digits at tens place = (8-5) = 3.
So, the original number is 35 and the new number is 53.

Answer:
-1 is in the domain of fºg
Step-by-step explanation:
Both functions are odd-degree polynomials (as written here), so both functions have a domain and range of "all real numbers."
-1 is in the domain of f(g(x))
The equation for a trapezoid is a+b/2*h. In this case, we have 3.2+8/2.
So 5.6=22.4/h. The height is 4 feet.
Answer:
A.
Step-by-step explanation:
4 is greater than the exact value of -2 and 4 is greater than -2. The exact values of -2 are 2 and -2. 4 is greater than both 2 and -2. Thus, a is correct.
