<span>5x - 6 = 4x + 8
-4x        -4x

x - 6 = 8
    +6   +6

x = 14

Answer: x = 14</span>

First let's get X to one side by subtracting 4x from both sides. (5x-4x) -6 = 8. x-6=8. Now we add 6 to both sides to isolate "x". x=8+6=14. Our answer is x=14.

Using a table of values, determine the solution to the equation below to the nearest fourth of a unit.
gayaneshka [121]
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

Joey answered 21 out of 25 questions correctly on a quiz what percent of his answers were correct
DedPeter [7]

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 \frac{x}{y} \times 100%.

Hence, the percentage of correct answer given by Joey is given by  

\frac{21}{25} \times 100 = 84%. ( Answer )

Answer:

2^{11}

Step-by-step explanation:

<u>Key indices rule: When dividing powers, subtract the indices and keep the base numbers constant.</u>

<u />\frac{2^{3} }{2^{-8} } 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 2^{11}.
