Find the equation of the line that is parallel to the
line y = -X- 7 and passes through the point
(-5, – 7). Write the equation in slope-intercept
form.
9514 1404 393
Answer:
y = -x -12
Step-by-step explanation:
The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...
y -k = m(x -h) . . . . . . line of slope m through point (h, k)
y -(-7) = -1(x -(-5))
y = -x -5 -7 . . . . subtract 7, eliminate parentheses
y = -x -12 . . . slope-intercept equation
An isosceles right-angled triangle is shown.
The area of the triangle is 200 cm?.
Work out the value of x.
Answer:
[tex]\boxed{x=4}[/tex]
Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4

What savings strategies have proven to be most effective?
Alice, Bob, and Carl arrange to meet for lunch on a certain day. They arriveindependently at uniformly distributed times between 1 pm and 1:30 pm on that day.
Required:
a. What is the probability that Carl arrives first?
b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?
c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?
d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?
Answer:
a. What is the probability that Carl arrives first?
Probability that Carl arrives first is ¹/₃ = 33.33% since their arrival times is uniformly distributed. The same probability applies to Bob and Alice.
b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?
Assuming that Carl arrived on time, 1:10 PM, we must determine the probability that Alice or Bob arrive between 1:20 and 1:30 (half the remaining time)
P = [3 · (¹/₂ - ¹/₃)] · [3 · (¹/₂ - ¹/₃)] = (3 · ¹/₆) · (3 · ¹/₆) = ¹/₂ · ¹/₂ = ¹/₄ = 25% chance that either Alice or Bob arrive more than 10 minutes later
c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?
P = 1 - 25% = 75%
d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?
I divided the 20 minutes by 5 to get ¹/₄:
P (|S - T| ≤ ¹/₄) = {[(x + ¹/₄)²] / 2} + (1 / 2x) + {[(⁵/₄ - x)²] / 2} = 0.09375 + 0.25 + 0.09375 = 0.4375 = 43.75%
Kevin bought 3 dvds for 45.99 how much would 7 dvds cost?
Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong.
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.
45.99 / 3 = 15.33
15.33 x 7 = 107.31
How do you solve

PLEASE HELPP‼️‼️ write in factored form g(x)= x^3 - 4x^2 - x + 22
Answer:
[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex] in the factored form will be:
[tex]g\left(x\right)=x^3-4x^2-x+22=\:\left(x+2\right)\left(x^2-6x+11\right)[/tex]Step-by-step explanation:
Given the function
[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex]
Use the rational root theorem.
[tex]a_0=22,\:\quad a_n=1[/tex]
[tex]\mathrm{The\:dividers\:of\:}a_0:\quad 1,\:2,\:11,\:22,\:\quad \mathrm{The\:dividers\:of\:}a_n:\quad 1[/tex]
[tex]\mathrm{Therefore,\:check\:the\:following\:rational\:numbers:\quad }\pm \frac{1,\:2,\:11,\:22}{1}[/tex]
[tex]-\frac{2}{1}\mathrm{\:is\:a\:root\:of\:the\:expression,\:so\:factor\:out\:}x+2[/tex]
[tex]=\left(x+2\right)\frac{x^3-4x^2-x+22}{x+2}[/tex]
as
[tex]\frac{x^3-4x^2-x+22}{x+2}=x^2-6x+11[/tex] ∵ [tex]x^3-4x^2-x+22=\left(x+2\right)\left(x^2-6x+11\right)[/tex]
so the expression becomes
[tex]x^3\:-\:4x^2\:-\:x\:+\:22=\left(x+2\right)\left(x^2-6x+11\right)[/tex]
Therefore,
[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex] in the factored form will be:
[tex]g\left(x\right)=x^3-4x^2-x+22=\:\left(x+2\right)\left(x^2-6x+11\right)[/tex]

Alligators captured in Florida are found to have a mean length of 2 meters and a standard deviation of 0.35 meters. The lengths of alligators are believed to be approximately normally distributed. What is the approximate length of an alligator at the 67th percentile of alligator lengths?
a. 2.01 meters.
b. 2.44 meters.
c. 2.21 meters.
d. 2.15 meters.
e. 2.09 meters.
Answer:
The correct option is (d). 2.15 meters.
Step-by-step explanation:
According to the given scenario, the approximate length of an alligator at the 67th percentile is as follows:
The length of an alligator is [tex]X \sim N(2,0.35)[/tex] .
Let us assume the [tex]P_{67}[/tex] be the 67th percentile
[tex]P(X <P67) = 0.67\\\\P(Z < \frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\\emptyset (\frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\ (\frac{P_{67 - 2 }}{0.35} ) = \emptyset^{-1 (0.67)\\\\[/tex]
[tex]\frac{P_{67 - 2 }}{0.35} = 0.44\\\\P_{67} = 2.154[/tex]
Hence, the correct option is (d). 2.15 meters

I have a rectangular garden. I usually grow cucumbers in 2/3 of my garden, but I want to take 3/4 of the cucumber section to grow
radishes. After I make this change, how much of my whole garden will
be radishes?
Answer:
[tex]\frac{1}{2}[/tex] of the garden will be radishes.
Step-by-step explanation:
Given a rectangular garden which grows cucumbers in [tex]\frac{2}{3}[/tex] of the garden.
[tex]\frac{3}{4}[/tex] of the cucumber section to grow radishes.
To find:
How much of the whole garden will be radishes?
Solution:
Let the total area of the garden = [tex]x[/tex] sq units
Then as per our assumption, total area to grow cucumbers:
[tex]\frac{2x}{3}[/tex] sq units
Cucumber area to grow radishes = [tex]\frac{3}{4}[/tex] of cucumber area
[tex]= \dfrac{3}{4}\times \dfrac{2x}{3}\\\Rightarrow \dfrac{x}{2}\ sq\ units[/tex]
Fraction of whole garden to grow radishes = Area to grow radishes divided by whole area of garden
[tex]\Rightarrow \dfrac{\frac{x}{2}}{x}\\\\\Rightarrow \bold{\dfrac{1}{2}}[/tex]
Therefore, [tex]\frac{1}{2}[/tex] of the garden will be radishes.

Solve the following equation. Only enter the numeric answer (no variables). 30=2.5(10-2x)
Answer:
x = -1
Step-by-step explanation:
30 = 2.5(10)(-2x) - you multiply by each
30 = 25 - 5x - then pass 25 to the other side and subract
5x = - 5x - then divide 5 / -5
x = -1 - and you have the answer
Answer:
x= -1
Step-by-step explanation:
distribute 2.5 through the parenthese
30=25-5x
move variable to the left hand side an change its sign
5x+30 =25
move constant to the right hand side and change the sign
5x=25 -30
calculate the difference
5x= -5
divide both sides of the equation by 5
x= -1

Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?
Answer:
The amount of each person's profit is:
Mack
= $1160
Jason
= $725
Yuri
= $1015
Step-by-step explanation:
Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?
Step 1
We calculate how much the profit is.
Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment
The profit = 1/5 of Investment
Hence = 1/5 × $14500
Profit = $2900
Step 2
We calculate the amount each of them receives.
Mack receives 2/5 of the profit,
= 2/5 × $2900
= $ 1160
Jason Receives 1/4 of the profit
= 1/4 × $2900
= $725
Yuri receives the rest of the profit
This is calculated as:
$2900 -($1160 + $725)
$2900 - $1885
= $1015
The amount of each person's profit is:
Mack
= $1160
Jason
= $725
Yuri
= $1015
