we need to find the equation of a like, in two different ways
a) slope-interceppt Y=mX+b
b) standard form aX+bY=c
the information we have is,
it's parallel to x+2y=5 (this mean the have the same slope
so, let's find it
x+2y=5
2y=5-x
y=5/2 - 1/2 x
the slope is m= -1/2
The other thing we know is the line passing through (-3,5)
so when x=-3 the value of Y has to be 5
So let's check, until now we have the slope, our line is y= -1/2x + B
let's find out the value of B, replacing the values of x and y
5= -1/2 * -3 +B
5= 3/2 + B
7/2= B
So, the answer to (a) is=
Y= -1/2 X + 7/2
b) we need to change from slope to standard form
Y= -1/2 X + 7/2
Y + 1/2 X= 7/2
i think that's standard form, but also you can divide for 7/2 to get
2/7 Y + 1/7 X = 1
Graph the line with the equation y = 2x - 1.
A line is uniquely defined by two points.
Since the points (0, -1) and (1, 1) lie on the graph (since they satisfy the equation), you can draw the line through these points.

How to solve the function?From the question, we have the function definition to be f(-5)
Also, we have the graphs to be f(x) and g(x)
The equation of the first graph is illustrated by the blue curve f(x), while the second is illustrated by the red curve
Because the function is f(x), we make use the blue curve
On the blue curve, we have
f(-5) = -6
The interpretation of the above equation is that
When x = -5, the blue curve has a value of -6

Jody received a 30% Commission on the profit when he sells over 20 cars in a month . if he sold 23 cars in October, resulting in $15000 profit for the dealership , how much did Joe earn in commission ?7.how much would be in an account when you turn 18 if, on the day you were born, 1000 were disposed into the account which returned 6% simple interest, and no longer disposes or withdrawals were made ?
Let's begin by identifying key information given to us:
Shoe Price = $120
Discount rate = 33% = 0.33
The Discount price of the shoe is calculated below:
[tex]\begin{gathered} DiscountPrice=ShoePrice-(ShoePrice\cdot DiscountRate) \\ DiscountPrice=120-\lbrack120\cdot(0.33)\rbrack=120-39.6 \\ DiscountPrice=80.40 \end{gathered}[/tex]Therefore, the discount price is $80.40

Chip Ahoy
The number of chocolate chips in an 18-ounce bag of
Chips Ahoy! chocolate chip cookies is approximately
normally distributed with a mean 1262 chips and a
standard deviation of 118 chips according to a study
by cadets of the U.S. Air Force Academy. (Why are
they studying chocolate chip cookies?}
What percent of bags has between 1026 and 1380 chocolate chips? Write your percent without the percent sign.
What percentage of the 18-ounce bags of chips ahoy! Cookies contains fewer than 1144 chocolate chips? Write the percent without the percent sign.
What percentage of the 18-ounce bags of chips ahoy! Cookies contains more than 1498 chocolate chips? Write the percent without the percent sign.
Using the normal distribution, it is found that:
81.85% of bags has between 1026 and 1380 chocolate chips.15.87% of the bags contain fewer than 1144 chocolate chips.2.28% of bags contain more than 1498 chocolate chips.Normal Probability DistributionThe z-score of a measure X of a variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the fraction presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation of the number of chips are given as follows:
[tex]\mu = 1262, \sigma = 118[/tex]
The proportion of bags that has between 1026 and 1380 chocolate chips is the p-value of Z when X = 1380 subtracted by the p-value of Z when X = 1026, hence:
X = 1380:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1380 - 1262)/118
Z = 1
Z = 1 has a p-value of 0.8413.
X = 1026:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1026 - 1262)/118
Z = -2
Z = -2 has a p-value of 0.0228.
0.8413 - 0.0228 = 0.8185.
Hence the percentage is 81.85%.
The proportion that has fewer than 1144 chips is the p-value of Z when X = 1144, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1144 - 1262)/118
Z = -1
Z = -1 has a p-value of 0.1587.
Hence the percentage is of 15.87%.
The proportion that has more than 1498 chips is one subtracted by the p-value of Z when X = 1498, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1498 - 1262)/118
Z = 2
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228
Hence the percentage is of 2.28%.

Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.For her parents' anniversary party, Laura is considering using one of two venues. A hotel in Dayton will cost $693 for a reservation, plus $51 per person. A restaurant in the same city will cost $60 per person, in addition to $684 for the reservation. In order to make the best decision. Laura figures out how many attendees it would take to have the venues cost thesame amount. How many attendees would that be? What would the total cost be?
Answer:
• The number of attendees = 1
,• Total Cost = $744
Explanation:
Let the number of attendees = n
A hotel in Dayton will cost $693 for a reservation, plus $51 per person.
[tex]\text{ Hotel's Cost, H\lparen n\rparen}=693+51n\cdots(1)[/tex]A restaurant will cost $60 per person, in addition to $684 for the reservation.
[tex]\text{ Restaurant's Cost, R\lparen n\rparen}=684+60n\cdots(2)[/tex]We want to find the number of attendees(n) at which the venues cost the same amount.
Equate the cost equations (1) and (2) above:
[tex]693+51n=684+60n[/tex]Solve the equation for n:
[tex]\begin{gathered} \text{Subtract 51n from both sides of the equation.} \\ 693+51n-51n=684+60n-51n \\ 693=684+9n \\ \text{Subtract 684 from both s}\imaginaryI\text{des of the equat}\imaginaryI\text{on} \\ 693-684=684-684+9n \\ 9=9n \\ \text{ Divide both sides by 9} \\ \frac{9}{9}=\frac{9n}{9} \\ n=1 \end{gathered}[/tex]The number of attendees it would take for the cost to be the same amount is 1.
We determine the total cost using any of the equations:
[tex]\begin{gathered} \begin{equation*} 693+51n\cdots(1) \end{equation*} \\ Total\text{ Cost}=693+51(1)=\$744 \end{gathered}[/tex]The total cost will be $744.
