Given:

\frac{4}{3}(x)-\frac{1}{3}=9

Let's evaluate and solve for x.

First step:

Add 1/3 to both sides of the equation

\begin{gathered} \frac{4}{3}(x)-\frac{1}{3}+\frac{1}{3}=9+\frac{1}{3} \\  \\ \frac{4}{3}(x)=\frac{28}{3} \end{gathered}

Cross multiply:

\begin{gathered} 4x(3)\text{ = 28(3)} \\  \\ 12x\text{ = }84 \end{gathered}

Divide both sides by 12:

\begin{gathered} \frac{12x}{12}=\frac{84}{12} \\  \\ x=7 \end{gathered}

ANSWER:

x = 7

3. Consider the functions f(x) = x2 + 10x – 5, g(x) = 8x + 1, and h(x) = 3x – 4. List the functions from least to greatest value
weeeeeb [17]
<u>x = 3</u>
f(x) = x²+ 10x - 5
f(3) = (3)² + 10(3) - 5
f(3) = 9 + 30 - 5
f(3) = 39 - 5
f(3) = 34

g(x) = 8x + 1
g(3) = 8(3) + 1
g(3) = 25

h(x) = 3x - 4
h(3) = 3(3) - 4
h(3) = 9 - 4
h(3) = 5

<u>x = 6
</u>f(x) = x² + 10x - 5
f(6) = (6)² + 10(6) - 5
f(6) = 36 + 60 - 5
f(6) = 96 - 5
f(6) = 91

g(x) = 8x + 1
g(6) = 8(6) + 1
g(6) = 48 + 1
g(6) = 49

h(x) = 3x - 4
h(6) = 3(6) - 4
h(6) = 18 - 4
h(6) = 14

I would explain to someone that you don't need to do any calculations to know the order of the functions when x is equal to 15 by knowing that f(x) is equal to 370, g(x) is equal to 121, and h(x) is equal to 41 to know that it is easy finding the function of x without calculating the answer.

Solve for x. x+5.39&gt;4.48
Evgesh-ka [11]

Answer:

\boxed {x > -0.91}

Step-by-step explanation:

Solve for x :

x + 5.39 > 4.48

-Subtract 5.39 on both sides:

x + 5.39 - 5.39 > 4.48 - 5.39

x > -0.91

So, therefore, the final answer is \boxed {x > -0.91}.
