Adam and his dad share the cost of the meal in the ratio of 2:3. Adam’s dad pays £52.20. What is the total cost of the meal
Ne4ueva [31]
We have to calculate the total cost of the meal. We know that Adam ( A ) and his dad ( D ) share the cost of the meal in the ratio 2 : 3 and that Adam`s dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds<span>. </span>

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.
andreev551 [17]

Answer:

f(x) = 6x -12

Step-by-step explanation:

We must write the function of the line in the form f (x) = mx + b

First calculate the slope m

m =\frac{y_2-y_1}{x_2-x_1}

y_2 = 18\\y_1 =6\\x_2=5\\x_1=3

m= \frac{18-6}{5-3} = 6

Then

f(x) = 6x +b

To have b replaced a point in the function

f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12

Finally the function is

f(x) = 6x -12
