2 answers:
Given:
The temperature is given in Fahrenheit (13 degree F).
To Find:
The correct temperature in Celsius.
Answer:
The temperature in Celsius is approximately -11 degree C.
Kyle has got an incorrect answer because instead of subtracting 32 form the temperature, he has added it.
Step-by-step explanation:
Any temperature can be changed from F to C by using the formula
So, we will convert the given temperature in F to C by performing three simple steps.
Step 1 - We will subtract 32 from the Fahrenheit temperature.
Step 2 - Multiply this number by 5.
Step 3 - Divide the resulting number by 9.
So,
Step 1: 13-32 = -19
Step 2: -19*5 = -95
Step 3: -95/9 = -10.55 approx
Thus, the temperature in Celsius is approximately -11 degree C.
Kyle has got an incorrect answer because instead of subtracting 32 form the temperature, he has added it.

Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus
Where
By substituting values for x1,x2,y1 and y2; the gradient becomes
Hence, the constant of variation is $1.50
