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 1

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.

Choose all of the correct statements.

Answers

Answer:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Step-by-step explanation:

Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:

d = 2r

From:

d = 2r

Divide both side by 2

r = d/2

The radius is half the diameter.

Circumference (C) of a circle is given by:

C = 2πr

C = π2r

Recall:

d = 2r

C = πd

C = πd

Divide both side by d

π = C/d

C = πd

Divide both side by π

d = C/π

C = πd

π = 3.14

C = 3.14 × d

Thus, the circumference is 3.14 times the diameter.

SUMMARY:

The correct statement from the above illustration is given below:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

it’s 6x + 19
because you do 6(x + 2) u multiply the 6 times the x which is 6x and then 6 x 2 which is 12 so ur equation would be 6x + 12 + 7 so you just add 12 and 7 which is 19
