Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20
Answer:
The domain of the function should be:
'x greater than or equal to negative -5'.
Hence, option A is true.
Step-by-step explanation:
Given the expression

The domain of a function is the set of input or arguments for which the function is real and defined
We know that the value, inside the radicand, is the number found inside a radical symbol which must be greater than 0, otherwise, it would make the function undefined,
i.e.
x-5 ≥ 0
x ≥ 5
In other words, the domain of the function should be:
'x greater than or equal to negative -5'.
Therefore, the domain of the function:
x ≥ 5

Hence, option A is true.

Answer:
d) 0.8 mile
Step-by-step explanation:
Coordinate of object B = (6, 6)
Coordinate of object C = (1, 4)
Coordinate of the archaeologist = (6, 1)
✍️Distance between Object B (6, 6) and the archaeologist (6, 1):
Distance = |6 - 1| = 5 units = 5 miles
✍️Distance between Object C (1, 4) and the archaeologist (6, 1):
Using the distance formula,
, we would have:



(nearest tenth)
Comparing how far each object is from the archaeologist, object C is 0.8 mile (5.8 - 5 = 0.8) farther than object B.
