Answer: Function A; 14 meters per seond
Step-by-step explanation:
do Distance/time for Function A: so you can show 140/10, or 280/20, it doesnt matter as they are all constant/consistent.
A has a rate of 14 m/s
B's rate is given, 13 m/s
So A has a faster rate of 14 meters per second
Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.
Answer:
B) 8 and 24.
Step-by-step explanation:
Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.
Regardless, let's work this out mathematically. Let the first number be <em>a</em> and the second number be <em>b</em>.
Their difference is 16. Hence:

The first number is three times the second number. So:

Substitute:

Solve for <em>b</em>. Subtract:

And divide both sides by two:

So, the second number is 8.
And since the first number is three times the second, the first number is 24.
Our answer is B as expected.
