Answer:

18

Step-by-step explanation:

We can use a proportion to find out the number of teachers that are needed.

3/70 = x/14,700

70x = 3 * 14,700

70x = 44,100

x = 630

630 teachers are needed altogether. Since there are already 612 teachers, the number of more teachers who are needed is the difference between 630 and 612.

630 - 612 = 18

Answer: 18

HELP WILL GIV YOU 30 POINTS BUT HELP ME
MrRa [10]

Answer:

3/4

Step-by-step explanation:

Constant of Proportionality is just a fancy way of saying slope (for a line passing through (0, 0), at least).

You can find it by looking at y/x, which will be equal at any point on the line (which is why it is a "constant").

So, for multiple points on the line:

1.5 / 2 = 3/4

3 / 4 = 3/4

4.5 / 6 = 3/4

2. If f(x) = x - 7 and g(x) = 2x + 5, then what is f(x) * g(x)?
AysviL [449]

Answer:

2x² - 9x - 35

Step-by-step explanation:

f(x) × g(x) = (x - 7)(2x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 5) - 7(2x + 5) ← distribute both parenthesis

= 2x² + 5x - 14x - 35 ← collect like terms

= 2x² - 9x - 35
