Answer:

If the ratio of one variable to the other is constant, then the two variables have a proportional relationship,

If x and y have a proportional relationship, the constant of proportionality is the ratio of y to x.

In this section, you will learn, how to find the constant of proportionality from a table which contains the values of x and y.

Group A

Money spent by Person 1 = £500

Money spent by Person 2 = £600

Money spent by Person 3 = £900

Money spent by Person 4 = £450

Sum of money spent by group A = £2,450

Average money spent by group A = $\frac{2,450}{4}$

⇒ Average money spent by group A = £612.5

Group B

Money spent by Person 1 = £700

Money spent by Person 2 = £500

Money spent by Person 3 = £680

Money spent by Person 4 = £500

Sum of money spent by group B = £2,380

Average money spent by group B = $\frac{2,380}{4}$

⇒ Average money spent by group B = £595

Hence, Group B had lower average spend.

If f(x) = StartFraction x Over 2 EndFraction + 8, what is f(x) when x = 10?

san4es73 [151]

Answer:

Step-by-step explanation:

You are given the function

$f(x)=\dfrac{x}{2}+8$

To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.

In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:

$f(10)=\dfrac{10}{2}+8=5+8=13$

Select the correct answer from each drop-down menu.

Ostrovityanka [42]

Answer:

Both questions are true.

Step-by-step explanation:

The general mathematical equation of a line can be written as $y = ax + b$ .

If we rearrange the two equations given in the question as follows:

$5y = 3x + 22$ and $20y = 12x + 11$

We can see that they follow the general equation we defined earlier so we can say that they represents linear lines.

The $20y = 12x + 88$ given in the second question also represents a similar linear line with a different slope.

So the two questions are both true.

I hope this answer helps.
