Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start Fraction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?

A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.

B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.

C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.

D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.

Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?

350 m/s

355 m/s

360 m/s

365 m/s

Answers

Answer:360 m/s

Step-by-step explanation:

The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

As we can see in the graph:

When the air temperature is 10°C the speed of sound is around 337m/s

When the air temperature is 20°C the speed of sound is around 344m/s

When the air temperature is 30°C the speed of sound is around 348m/s

When the air temperature is 40°C the speed of sound is around 355m/s

From the above observation, the air temperature increases the speed of the sound increases.

So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.

Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.
