Answer:
D
Step-by-step explanation:
Simplifying x + 3 + x + 4 = x + 7 + 2x + 7 Reorder the terms: 3 + 4 + x + x = x + 7 + 2x + 7 Combine like terms: 3 + 4 = 7 7 + x + x = x + 7 + 2x + 7 Combine like terms: x + x = 2x 7 + 2x = x + 7 + 2x + 7 Reorder the terms: 7 + 2x = 7 + 7 + x + 2x Combine like terms: 7 + 7 = 14 7 + 2x = 14 + x + 2x Combine like terms: ...

2) -7 i think
Step-by-step explanation:
The rate of change of the given function at [-1,3] is 5
Further explanation:
Given function is:

And the interval is:
[-1,3]
In order to find the rate of chnage of function the given function's value is calculated at both points and divided by their difference
The formula is:

Here,
x_1 = -1
x_2 = 3
So,

Putting the values in the rate of change formula:

The rate of change of the given function at [-1,3] is 5

Answer:
270.06
How to solve:
Write a function:
f(t)=270(1+0.001)^{t/10}
23 years→23/10→2.3 decades
Plug in t=2.3
f(2.3)=270(1+0.001)^{2.3/10}
=270.062076106
≈270.06
