Answer:
digit in the unit's place originally = 5
Step-by-step explanation:
x + y = 14
xy - yx = 36
Now, the only single digits that sum up to 14 are;
9 + 5 = 14
8 + 6 = 14
We can't use 7 + 7 because they said there is a difference when the numbers are reversed.
Now, let's assume 95 is the original number since we are told when it is reversed it is lesser.
Thus, when reversed we have 59.
Difference = 95 - 59 = 36
Thus,unit number of original number = 5
Answer:
A(-2,0) B(-4,0) C(-5,2) D(-1,2)
Step-by-step explanation:
Answer:
the domain of f(x) is R ⇒ ] -∞ , ∞[
the domain of h(x) is x ≤ -5 ⇒ ] -∞ , -5]
Step-by-step explanation:
h(x) = \sqrt[8]{-2x-10}
-2x - 10 ≥ 0
-2x ≥ 10
x ≤ -5
