What is the slope of a line that is perpendicular to the line represented by the equation x – y = 8? 1 −1 8
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
\(x-y=8\implies -y=-x+8\implies y=\stackrel{\stackrel{m}{\downarrow }}{1}x-8\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\)

Step-by-step explanation:
First, do (-1)^3. This can be written as -1*-1*-1, which equals to -1.
You now have -1 + 10^2 + 4*(-5)
According to order of operations, you would do 4*-5 next. It is -20.

s an initial service charge of $100 plus $50 per hour of use, and $20 per hour for the driver. Darren rented a limousine for his wedding. The expression \large 100+h\left(50\right)+h\left(20\right) represents his cost for h hours.
Part A: Find a simpler way to calculate the cost. Explain.
Part B: Find the cost for 7 hours of rental time.
Answer:
A: $100 + $70h = Cost
B: $590
Step-by-step explanation:
A: you can combine the use rate and the driver rate together since they both have the save variable.
B: $100 + $70 (7) = Cost
$100 + $490 = Cost
$590 = Cost

What is the slope of the line perpendicular to 2x-3y=8
Answer:
y = - \(\frac{3}{2}\)x - \(\frac{8}{3}\)
Step-by-step explanation:
2x-3y=8
rewrite, solve for y
3y = 2x - 8
divide by 3
y = \(\frac{2}{3}\)x - \(\frac{8}{3}\)
perpendicular = negative reciprocal slope = - \(\frac{3}{2}\)

Describe the relationship between the probability of an event and its complement.
If the probability of an event is 0.95, what is the probability of its complement?
The probability of the complement of the event is 0.05.
The complement of an event is the probability of that event not occurring. The relationship between the probability of an event and its complement is that they always add up to 1.
Therefore, if the probability of an event occurring is p, then the probability of its complement not occurring is 1-p.
In the case where the probability of an event is 0.95, the probability of its complement not occurring would be 1-0.95 = 0.05. This means that the probability of the complement of the event is 0.05.
This concept is important in probability theory and is used to calculate the probabilities of events and their complements. It allows us to consider all possible outcomes of a given situation and calculate the likelihood of each of them.

Investing for college, Jake originally put $5000 into a savings account that paid 3.5%. There is now $6400 in the account. How long did Jake have the money in the savings account?
Jake put the money in the savings account for about 17.5 years.
Simply explained, a savings account is a place where you can deposit funds and earn interest.
Most people won't pay any tax on their savings interest because it is paid tax-free. Only people with extremely big sums of savings would need to be concerned about this, which is less than 5% of us as basic-rate taxpayers can earn £1,000/year tax-free and higher-rate taxpayers £500.
The interest calculated in a savings account is compound interest:
So let us now calculate the savings rate of interest at 3.5% for the whole time
We know that
\(A=P(1+r)^n\)
Where A is the amount , P is the principal , r is the rate and n is the time.
Substituting the values we calculate the value of x.
6400 = 3500 ( 1+0.035 )ⁿ
or, n = 17.54..
So the time required will be about 17.5 years in the savings account.

given: - > 10. choose the solution set. {x | x < -40/7} {x | x > -35/2} {x | x < -35/2} {x | x > -40/7}
The solution set is {x | x < -35/2} and {x | x > -40/7}.
To find the solution set of these two inequalities, first we need to solve them.
The first inequality is x < -40/7. To solve this inequality, we need to divide both sides of the inequality by -7. This gives us x > -40/7.
The second inequality is x > -35/2. To solve this inequality, we need to divide both sides of the inequality by 2. This gives us x < -35/2.
Therefore, the solution set is {x | x < -35/2} and {x | x > -40/7}.

37=|y+22l please help me this one is hard
Answer:
y= 15 and y= -59
Step-by-step explanation:
Given
37 = |y+22|
We have 2 possibilities
-what is inside the absolute value is positive
37 = y+22
-what is inside the absolute value is negative
37 = -(y+22), distribute the negative sign in parenthesis
37 = -y -22
Solve the 2 possibilities to find y:
-when what is inside the absolute value is positive
37 = y+22, subtract 22 from both sides of the equation
37-22 = y +22-22, combine like terms
15 =y
-when what is inside the absolute value is negative
37 = -y -22, add 22 to both sides
37+22 = -y -22+22, combine like terms
59 = -y, multiply both sides by -1
-59 =y
Solution:

Step-by-step explanation:
A student ran out of time on a multiple-choice exam and randomly guessed the answers for two problems. Each problem had 4 answer choices –a,b,c,d – and only one correct answer. What is the probability that he answered both of the problems correctly?
Do not round your answer.
\({\huge{\fbox{\tt{\blue{ANSWER}}}}}\)
______________________________________
The probability of answering a single problem correctly by randomly guessing is 1/4, since there are 4 answer choices and only one correct answer. Since the student randomly guessed the answer to both problems, the probability of answering both problems correctly is:
(1/4) x (1/4) = 1/16
Therefore, the probability that the student answered both problems correctly is 1/16.
permieter of 2 rectangles is 54 cm.
work out the area of a square
The Area of Square is 81 cm².
let the side of the square which is length for both rectangles be a.
let the width of rectangle be x and y.
So, x+ y= a
sum of perimeters= 54
2 (a +x ) + 2 (a+ y) = 54
2a+ 2x + 2a+ 2y = 54
2a + 2a + 2(x+ y) = 54
4a + 2 (a) = 54
4a + 2a = 54
6a = 54
a= 54/6

It is always a good practice to simplify the result whenever possible, but in this case, V14 is the simplest form of the product of V7 and V2.
To multiply the square roots V7 and V2, we can combine the numbers inside the square roots and simplify the result.
V7 * V2 = V(7 * 2) = V14
Multiplying the numbers under the square roots, we get 7 * 2 = 14. Therefore, the product of V7 and V2 is V14.
This means that the square root of 14 is the result of multiplying V7 and V2. However, it is important to note that V14 cannot be further simplified because 14 does not have any perfect square factors.
In summary, the product of V7 and V2 is V14. It is worth mentioning that when multiplying square roots, we can multiply the numbers inside the square roots and keep the square root symbol intact, unless the numbers inside have perfect square factors that can be simplified further.
