Let's call f(x) = 2x - 4 and g(x) = 3⁻ˣ + 1.
<span>First, you need to evaluate each function at the given values of x.</span>
f(1) = 2(1) - 4 = -2
f(3.25) = 2(3.25) - 4 = 2.50
f(2.5) = 2(2.5) - 4 = 1
f(2) = 2(2) - 4 = 0
Similarly:
g(1) = <span>3⁻¹ + 1 = 1.33
g(3.25) = </span><span>3⁻³'²⁵ + 1 = 1.03
g(2.5) = </span>3⁻²'⁵ + 1 = 1.06
g(2) = 3⁻² + 1 = 1.11
Now, look for the value of x for which f(x) ≈ g(x): this happens for x = 2.5
Therefore the correct answer is c) x ≈ 2.5
Answer:
84%
Step-by-step explanation:
Joey gives 21 correct answers out of 25 questions on a quiz.
We have to calculate the percent of Joey's correct answer.
Now, percentage of x out of y is given by the simple expression
%.
Hence, the percentage of correct answer given by Joey is given by
%. ( Answer )
Answer:

Step-by-step explanation:

divide both side by 8


Answer:

Step-by-step explanation:
<u>Key indices rule: When dividing powers, subtract the indices and keep the base numbers constant.</u>
<u />
Based on the rule above, the indices are determined by 3--8, which is 11.
The base number is kept constant.
Therefore, the answer is
.
