Which of the following is the inverse of y=
6^x?
Answer:
y = (ln x) / (ln 6)
Step-by-step explanation:
1. Exchange x and y: x = 6^y
2. Solve for y: Take the natural log of both sides:
ln x = y ln 6
Then: y = (ln x) / (ln 6)
Note: y = (log x) / (log 6) is also correct
(Hurry, please!) A line passes through the point (8,-1) and has a slope of 5/4. Write an equation in slope intercept form for this line.
Answer:
y = 5/4x -11
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b
where m is the slope and b is the y intercept
y = 5/4 x + b
Substitute the point into the line
-1 = 5/4(8) +b
-1 =10 +b
Subtract 10 from each side
-11 = b
y = 5/4x -11
Answer:
[tex]\huge \boxed{y=\frac{5}{4} x-11}[/tex]
Step-by-step explanation:
The slope-intercept form of a line is written as,
[tex]y=mx+b \\ \\ \\ \sf m= slope \\ \\ b=y -intercept[/tex]
The slope is given.
[tex]\displaystyle y=\frac{5}{4} x+b[/tex]
The line passes through the point (8, -1).
[tex]x=8 \\ \\ y=-1[/tex]
Plugging in the values.
[tex]\displaystyle -1=\frac{5}{4} (8)+b[/tex]
Solving for b or y-intercept of the line.
[tex]\displaystyle -1=\frac{40}{4} +b[/tex]
[tex]-1=10+b[/tex]
[tex]-11=b[/tex]
The y-intercept of the line is -11.

The value of each digit in a number is known as the place value. The number is 412,630.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10.As per the given statement, the part of the numbers can be written as,
30 ones = 30 × 1 = 302 thousands = 2 × 1,000 = 2,0004hundred thousands = 4 × 100,000 = 400,00060 tens = 60 × 10 = 600100 hundreds = 100 × 100 = 10,000Now, summing up all, we will get the number,
Number = 30 + 2,000 + 400,000 + 600 + 10,000
= 412,630

Jon is 3 years younger than Laura. The product of their ages is 1,330. If j represents Jon's age and j + 3 represents Laura's age, what value of j
could be Jon's age?
Answer:
35
Step-by-step explanation:
j(j + 3) = 1330
Trial and error method:
j and j + 3 are pretty close to each other. Start by taking the square root of 1330.
sqrt(1330) = 36.5. One number is less than 36.5 and the other number if 3 more than that.
Since the product of j and j + 3 is 1330 which ends in 0, it is a multiply of 10 and 5.
Try 35 and 38. 35 * 38 = 1330
Answer: 35
Equation method:
j(j + 3) = 1330
j^2 + 3j - 1330 = 0
(j + 38)(j - 35) = 0
j = -38 or j = 35
Answer: 35
If Jon is 3 years younger than Laura, then Jon's age is 35years.
Let the age of John be j
If Jon is 3 years younger than Laura, then;
Laura's age = j + 3
Based on the question, we are told that the product of their ages is 1,330, this can be expressed as:
j(j+3) = 1330
Expand
j²+3j = 1330
j²+3j - 1330 = 0
j²+38j-35j-1330 =0
j(j+38)-35(j+38) = 0
(j−35)(j+38) = 0
j = 35 and j = -38
j = 35
Hence Jon's age is 35years.

How many solutions does the system have?
Answer: A
Step-by-step explanation:
There are 2 ways to solve this problem.
Solution 1:
Since we are given two equations, we set them equal to each other to find where they intersect, the solution.
3x+3=-2x+3 [combine like terms]
5x=0 [divide both sides by 5]
x=0
Now that we have x=0, we can plug it into either equation to find the point of intersection.
y=3(0)+3
y=3
We know that the point of intersection is (0,3).
-------------------------------------------------------------------------------------------------------------
Solution 2:
This way of solving the problem doesn't require any calculations. All it requires is an understanding of slope-intercept form equation. From the two equations given, we know that they are linear lines. Linear lines can only intersect once. Knowing this, we know that there can only be exactly one solution.

Question:
At the beginning of the months, a consumer had $437.52 of in his bank account. During which he made deposits of $80, $256 and $217.14 and write checks of $115.98 and $108.90 - What balance left?
Answer:
The customer's balance is $765.78
Step-by-step explanation:
Given
Start Amount = $437.52
Deposits = $80, $256 and $217.14
Withdrawals (Checks) = $115.98 and $108.90
Required
Determine his balance
We start by calculating the total deposits made by the customer
[tex]Total\ Deposits = \$80 + \$256 + \$217.14[/tex]
[tex]Total\ Deposits = \$553.14[/tex]
Next, we calculate the total withdrawals (checks)
[tex]Total\ Withdrawals = \$115.98 + \$108.90[/tex]
[tex]Total\ Withdrawals = \$224.88[/tex]
At this point, we can now calculate the customer's balance as follows;
[tex]Balance =Start\ Amount + Total\ Deposits - Total\ Withdrawals[/tex]
[tex]Balance = \$437.52+ \$553.14 -\$224.88[/tex]
[tex]Balance = \$765.78[/tex]
Hence, the customer's balance is $765.78
The balance left in the consumer's account is $765.78.
The amount of money in the consumer's account increases with the deposits made and reduces when she writes checks.
The total value of the deposits have to be determined first.
Total value of the deposits = $256 + $217.14 + $80 = $553.14
The value of the checks written has to be determined
$115.98 + $108.90 = $224.88
Add the value of deposit, subtract the value of checks from the beginning balance
$437.52 + $553.14 - $224.88 = $765.78

Answer:
Option (A)
Step-by-step explanation:
If a function 'f' is an odd function,

If a function 'f' is an even function,
f(-x) = f(x)
In this question given function is,
f(x) = [tex]\frac{220}{x^3}[/tex]
To check the given function is odd or even,
f(-x) = [tex]\frac{220}{(-x)^{3} }[/tex]
= [tex]-\frac{200}{x^{3}}[/tex]
Therefore, from the definition of even and odd functions,
Function 'f' is an odd function.
Option (A) will be the correct option.
In the past, 75% or less of the tourists who visited Tacoma went to see the glass blowing museum. The management of the museum recently undertook an extensive promotional campaign. They are now interested in determining whether the promotional campaign actually increased the proportion of tourists visiting the museum. The correct set of hypotheses is
Answer:
H0 : p ≤ 0.75 against Ha : p > 0.75
Step-by-step explanation:
We formulate our null and alter native hypotheses as
H0 : p ≤ 0.75 against Ha : p > 0.75
In the question the claim whether the promotional campaign actually increased the proportion of tourists visiting the museum is given which is formulated as alternative hypothesis.
So when we formulate the alternative hypothesis as Ha : p> 0.75 the null hypothesis is H0 p ≤ 0.75
Where p is the probability = 75% = 75/100 = 0.75

(9x - 4x2 + 9) + (-x3 + 4x2 - 3)
Answer:
The solution to the given expression is -x³ + 9x + 6
Step-by-step explanation:
(9x - 4x² + 9) + (-x³ + 4x² - 3)
Since there is a positive sign in front of the second parentheses, then the terms inside will stay the same.
9x - 4x² + 9 - x³ + 4x² - 3
Group terms together that are alike. Also known as like terms.
-x³ + (-4x² + 4x²) + 9x + (9 - 3)'
Combine like terms.
-x³ + 9x + 6
Answer:
- [tex]x^{3\\}[/tex] + 9x + 6
Step-by-step explanation:
First, you need to combine like terms. Like terms, when dealing with exponents can be categorized by their powers.
hIn this case, 9x stands alone, because there is no other coefficient with the power of just x.
9x
Next, we can look at the -4x^2. The other similar coefficient is + 4x^2. We can combine both of those, which will equal out to 0.
Next, you have 9. It can be combined with -3, since none of them have an exponent attached. It will equal 6
9x + 6
We also have a -x^3 left over. There is no like term to combine with it, so we can leave it as is.
Our problem now looks like
9x + 6 - [tex]x^{3}[/tex]
You can rearrange them in the proper order, so it will look like,
- [tex]x^{3}[/tex] + 9x + 6.
And there you have it!
