Answer:
D' (1, 3)
Step-by-step explanation:
When reflected across the y = x line, the "x" and "y" coordinates switch.
If D is (3, 1), then:
x = 3
y = 1
Switch the "x" and "y" values, and rewrite as (x, y).
x = 1
y = 3
D' (1, 3)
It is D because the segments don’t intersect and are just moving 2 units to the left. They are the same distance apart.
Hope it helps and is correct :)

formula :-
Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
Answer:
3/4 or 0.75 decimal
Step-by-step explanation:
Simplify the following:
(2/3)/(8/9)
Hint: | Write (2/3)/(8/9) as a single fraction.
Multiply the numerator by the reciprocal of the denominator, (2/3)/(8/9) = 2/3×9/8:
(2×9)/(3×8)
Hint: | In (2×9)/(3×8), divide 9 in the numerator by 3 in the denominator.
9/3 = (3×3)/3 = 3:
(2×3)/8
Hint: | In (2×3)/8, divide 8 in the denominator by 2 in the numerator.
2/8 = 2/(2×4) = 1/4:
Answer: 3/4
