Answer:

Important! The "x" is just a place-holder! And "f" is just a name.

These are all the same function:

f(x) = 1 − x + x2

f(q) = 1 − q + q2

w(A) = 1 − A + A2

pumpkin(θ) = 1 − θ + θ2

Harry saved $100 each week for 8 weeks. He earned $48 on his savings of $800. What interest did Harry earn for every $100?

ch4aika [34]

<h2>Explanation:</h2><h2></h2>

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

$\text{Amount of money saved}=8\times 100=\$800$

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

$I=\frac{48}{8}=\$6$

So, in conclusion Harry did earn $6 in interest for every $100

Does the table show a direct proportional relationship? If so, what is the constant of proportionality?

lesantik [10]

Answer:

C. Yes, 3.5.

Step-by-step explanation:

If there is a relationship of direct proportionality for every ordered pair of the table, then the constant of proportionality must the same for every ordered pair. The constant of proportionality ( $k$ ) is described by the following expression:

$k = \frac{y}{x}$ (1)

Where:

$x$ - Input.

$y$ - Output.

If we know that $(x_{1}, y_{1}) = (13, 45.5)$ , $(x_{2}, y_{2}) = (14, 49)$ and $(x_{3}, y_{3}) = (15, 52.5)$ , then the constants of proportionalities of each ordered pair are, respectively:
