Answer:
-a^5/(8b^7)
Step-by-step explanation:

(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
a^-b = 1/a^b

What is the answer to 1/7 x 8
Answer:
8/7
Step-by-step explanation:
is 10/18 in decimal form a terminates or repeating decimal
Hey there! I'm happy to help!
To write a fraction as a decimal, you simply divide the numerator by the denominator.
10÷18=0.55555.... (the 5s never end!)
We see that the 5s repeat forever. This means that this is a repeating decimal.

ANSWER AS SOON AS POSSIBLE PLEASE! Jessica has $19. She buys 4 apples for x dollars each. Levi has $30 and buys 7 apples for x dollars each. Write an expression of how much money altogether they would have left?
This is the same as -11x+49
=========================================================
Explanation:
1 apple = x dollars
4 apples = 4x dollars, after multiplying both sides by 4
If Jessica buys 4 apples, then she spends 4x dollars.
Jessica has $19, so she'll have 19-4x dollars leftover after buying those four apples.
Similarly, Levi will have 30-7x dollars leftover when buying 7 apples for x dollars each.
Add up the leftover amounts to get...
(jessica's leftovers) + (Levi's leftovers)
(19-4x)+(30-7x)
19-4x+30-7x
(19+30)+(-4x-7x)
49-11x
This is the same as -11x+49 since you can think of 49-11x as 49+(-11x), and we can add two terms in any order we want.
---------------------------
An alternative viewpoint
Pool up Jessica's and Levi's amount they start with to get 19+30 = 49 dollars
Jessica buys 4 apples and Levi buys 7 apples. In total, this is 4+7 = 11 apples. At x dollars an apple, they spend 11x dollars. So they'll have 49-11x dollars leftover after buying those 11 apples.

What are two things we look for in an equation that can tell us what's NOT in it's domain?
Answer:
1. Value for which denominator is 0.
2. Value for which we get negative sing inside the root or log.
Step-by-step explanation:
Domain is the set of input values.
If a function is not defined for a set of value then they are NOT in it's domain.
Two we look for in an equation that can tell us what's NOT in it's domain :
1. Value for which denominator is 0.
2. Value for which radicand is negative because negative values inside the square roots are not real. Value for which log values are negative because log is not defined for negative values.

BRAINLIEST ASAP! PLEASE HELP ME :)
I need help with Part 2 of the question.
Steps to solve:
6a + 12 = 3(2a + 1) + 5
~Distribute right sides
6a + 12 = 6a + 3 + 5
~Simplify
6a + 12 = 6a + 8
~Subtract 12 to both sides
6a = 6a - 4
~Subtract 6a to both sides
0 = 4
Therefore, there are no solutions.

which graph shows the function f(x)=x with an input of (f(x-3)
please help me asap!!
Answer:
Step-by-step explanation:
B
The correct graph of the function is shown in option (B).
What is graph?A graph is a diagram that depicts the relationship between two variables, usually measured along opposite axes in a pair, is used.
The given function is,
f(x) = y = x (1)
To find the graph of f(x -3),
Substitute x = x- 3 in equation (1),
y = x- 3
The slope of the graph is 1,
And the y intercept at x = 0,
y = -3
So the graph of the function y = x - 3 can be plotted as,
Hence option (B) is correct option.

On a map, 2.5 inches represents 300 miles. How many miles are represented by 6 inches?
А .05 miles
00
.40 miles
С
600 miles
D
720 miles
Answer:
D. 720 miles
Step-by-step explanation:
First, we know that 2.5 inches represents 300 miles. This means that we have to find out how much 1 inch represents in miles. So, we take 300/2.5. This results in 120. So, 1 inch represents 120 miles. Then, we take 6*120 which gets us 720 miles.
A map of 720 miles represented by 6 inches.
It is given that 2.5 inches represent 300 miles.
It is required to find the miles represented by 6 inches.
How many miles are represented by 6 inches?First we have to find how many miles we get in one inch. Then we find in how many miles does 6 inches have.
In 2.5 inches, the map represents 300 miles.
In 1 inch, a map represents 300/2.5 miles which are equal to 120 miles.
So, in 6 inches, a map represents (120×6) miles which are equal to 720 miles.
Thus in 6 inches, a map represents (120×6) miles which are equal to 720 miles.

QR = 2B
PR = base = B
Perimeter = P = 105
P = PQ + QR + PR

Answer: REMEMBER TO RATE 5 STARS AND GIVE ME A HEART, THANKS!!!
The High Shcool Basketball team played a total of 25 games.

Find the simplified product:[tex]\sqrt{2x^{3} }-\sqrt{18x^{5} }[/tex]
Correct Question: Find the simplified product: [tex] \sqrt{2x^3}*\sqrt{18x^5} [/tex]
Answer:
[tex] 6x^4 [/tex]
Step-by-step explanation:
Based on the rules of radicals, since [tex] \sqrt{2x^3} [/tex] and [tex] \sqrt{18x^5} [/tex] has the same index (square root), therefore:
[tex] \sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5} [/tex]
To simplify this, multiply their bases together, and add their exponents.
[tex] = \sqrt{2*18x^{3+5} [/tex]
[tex] = \sqrt{36x^{8} [/tex]
Simplify further
[tex] = \sqrt{36}*\sqrt{x^8} [/tex]
[tex] = \sqrt{6*6}*\sqrt{x^4*x^4} [/tex]
[tex] = 6x^4 [/tex]
