Given f(x) = 5x^6 what is the domain?5 < X ≤ 6x ≥ 0X ≤ Oall real numbers

Vilka [71]1 year ago

The domain is the set of all possible x-values which will make the function "work", and will output real y-values

\begin{gathered} \text{Let} \\ f(x)=5x^6 \\  \end{gathered}

there is not a value for x, that makes the function does not "work", so x can take any value, in other words all real numbers

so, the answer is all real numbers

7. You are ordering sweaters from American Eagle. Each sweater costs $25. They also charge a shipping fee of $7. You spent. $132
NARA [144]

Answer:

Step-by-step explanation:

Alright, after reading this problem, let’s highlight some key points. Each sweater costs $25, we can write that down as 25x because will represent the amount of sweaters we buy. But we have a shipping fee of $7, so we will +7 to our highlights. And the total money spent was $132.

So far, we have: 25x + 7 = 132

Let’s subtract the 7 from the 132. Now we have: 25x = 125

Then we can divide by 25 on each side, and get x by itself.

X = 5 sweaters.

BONUS: Let’s replace 5 for our x to prove our answer

25(5) + 7 = 132 >>> 125 + 7 = 132 >>> 132 = 132 :D

There you go!! We buy 5 sweaters from American Eagle..!

Which is the simplified form of the expression 3(7/5x+4) - 2(3/2 - 5/4x)?
Kruka [31]

Answer:

B. \frac{67}{10} x + 9

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)

\frac{21}{5}x + 12  - \frac{6}{2} + \frac{10}{4} x

\frac{21}{5} x + 12 - 3 + \frac{10}{4} x

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9

Thus, the answer is \frac{67}{10} x + 9.
