Answer:
(8, 72)
Step-by-step explanation:
Here we have two separate equations for y: y = 9x and y = 2x + 56.
Equating these equations eliminates y temporarily; we get:
9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.
Then, by the first equation, y = 9(8) = 72.
The solution is (8, 72).
Answer:
the compound inequality that matches the number line is A
Step-by-step explanation:
For this case we have an equation of the potential type.
y = A * (b) ^ x
Where,
A: initial amount
b: rate of increase
x: number of days
Substituting values we have:
y = 2 * (2) ^ x
For day 4 we have:
y = 2 * (2) ^ 4
y = 32 times
Answer:
he does ride around the block on day 4 about:
y = 32 times
