Tell whether x and y are in a proportional relationship. If so, find the unit rate. Let y be the temperature x hours after midnight. The temperature is 60∘F at midnight and decreases 2∘F every 1/2 hour
Answers
Answer:
x and y are not in a proportional relationship
Step-by-step explanation:
The temperature is 60 F at midnight, and decreases 2 F every 1/2 hour, x represents hours, y represents temperature.
Plot (0, 60) , (0.5, 58) , and (1, 56)
Draw a line through the prints.
The graph is a line that does not pass through he origin.
SO, x and y are not in a proportional relationship.

Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x
Answers
Answer:
y = 2x - 1
Step-by-step explanation:
y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.
Answer:
y=2x-1
Step-by-step explanation:
notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

The roadway is about ____ meters above the water.
Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.
The length of the bridge is about ____ kilometers.
Answers
b:8.04 km
The roadway is about 60.66 meters above the water.
The length of the bridge is about 8.04 kilometers.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
The length of the roadway above the water = 199 ft
1 ft = 0.3048 m
Multiply 199 on both sides.
199 ft = 60.66 m
The bridge has a length of 26,372 feet.
1 ft = 0.0003048
Multiply 26372 on both sides.
26372 ft = 26372 x 0.0003048
26372 ft = 8.04 km
Thus,
The roadway in meters is about 60.66 meters above the water.
The length of the bridge in km is about 8.04 kilometers.

Answers
Answer:
Step-by-step explanation:
The correct pairs of equivalent expressions are given below.
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
What is the expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have given that,
All the expression are,
(5 + 2b)+(2b + 3/2)
(-14 + 3/2b)-(1 + 8/2b)
(-10 + b)+(7b -5)
(7/2b - 3)-(8 + 6b)
Now, We have to determine the equivalent expression as;
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
Thus, The correct pairs of equivalent expressions are given below.
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
