Write an equation in slope-intercept form for the line with slope -1/2 and y-intercept -7
Answer:
well slope intercept form is
y=mx+b
now m is slope and b is y intercept.
so just plug it in
y= -1/2x - 7
Answer:
the slope intercept form is
y=mx+b
y= -1/2x - 7
Step-by-step explanation:

Step-by-step explanation:
Benny the Barber (see Question 1) is considering the addition of a second chair. Customers would be selected for a haircut on a FCFS basis from those waiting. Benny has assumed that both barbers would take an average of 20 minutes to give a haircut, and that business would remain unchanged with customers arriving at a rate of two per hour. Find the following information to help Benny decide if a second chair should be added: Part (a): The average number of customers waiting. Part (b): The average time a customer waits. Part (c): The average time a customer is in the shop.
According to the information presented, Benny should decide not to add a second chair because the average number of clients waiting is 1 (very low), the average waiting time for a client is 10 minutes (very low), and the average time a customer is in the store is 20 minutes (very low).
According to the information, an average of 2 clients arrive at the hairdresser for every hour (60 min) and each cut takes a maximum of 20 minutes. Therefore, the hairdresser would have an average of 40 minutes busy and 20 minutes free for each hour.
Additionally, customers who must wait do not have to spend a long time waiting in the store because the maximum waiting time is 10 minutes (in the case that both customers arrive at the same time).
Below is a graph where the information of both cases is compared (with an additional chair and without an additional chair) and it is inferred that an additional chair is not necessary because the number of clients waiting and the waiting time is not high.

What is the slope of this line?
Answer:
1, -6
Step-by-step explanation:
Subtract the units on the grid from one point to the other to get the slope. You go over 1 and down 6 to get to the other point.
A marathon is 26.2 miles long. Jarrod is running a marathon and has completed 17.75 miles. How
many more miles to the finish line?
Answer:
Jarron has 8.45 more miles to get to the finish line.
Step-by-step explanation:
All we have to do is subtract the total number of miles by the number of miles Jarron has completed.
So: 26.20 - 17.75 = 8.45
26.2 - 17.75 = 8.45
All you need is subtraction because you are finding what is left.
You can find 8.45 by using a calculator or solving in your head, it would just take longer.

Find the measure of each angle indicated.
Answer:
1.50° 2.65°
Step-by-step explanation:
let x be the unknown angle
1. 32+98+x=180(sum of angles in a ∆ equal to 180°)
130+x=180
x=180-130
x=50°
2. 25+90+x=180
115+x=180
x=180-115
x=65°

The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (Time.com). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars.
Private Colleges
53.8 42.2 44.0 34.3 44.0
31.6 45.8 38.8 50.5 42.0
Public Colleges
20.3 22.0 28.2 15.6 24.1 28.5
22.8 25.8 18.5 25.6 14.4 21.8
(a) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for private colleges. (Round the standard deviation to two decimal places.)
(b) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for public colleges. (Round the standard deviation to two decimal places.)
(c) What is the point estimate (in thousand dollars) of the difference between the two population means? (Use Private − Public.)
We estimate that the mean annual cost to attend private colleges is $ more than the mean annual cost to attend public college
(d) Develop a 95% confidence interval (in thousand dollars) of the difference between the mean annual cost of attending private and public colleges. (Use Private − Public. Round your answers to one decimal place.)

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
–x + 5y = 14; (–5, –2)
A. y = 5^x – 27
B. y = -1/5x – 27
C. y = -1/5x – 15
D. y = -5^x – 27
Answer:
D. y = -5^x – 27
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line perpendicular to − x + 5 y = 14 .
y = − 5 x − 27 PERPENDICULAAR

solve the system y=6x=5 y=3x-23
Answer:
False θ·θ.................
Answer:
x = -28/3
y = -51
Step-by-step explanation:
Let's solve for X first
6x + 5 = 3x - 23
-3x -5 (like terms)
3x = -28
/3 /3 (divide by 3)
x = -28/3
y = 6(-28/3) + 5
y = -51

(a^3 + 6a^2 - 11a -38) ÷ (a+7)
Answer:
remainder=-10
Step-by-step explanation:
a^3+6a^2-11a-38=a^3+7a^2-a^2-7a-4a-28-10=a^2(a+7)-a(a+7)-4(a+7)-10=(a+7)*(a^2-a-4)-10
or you can find remainder replacing a with -7:
-7^3+6*-7^2+7*11-38= -10
Answer:
- 10Step-by-step explanation:
(a³ + 6a² - 11a -38) ÷ (a+7) = a² - a - 4 rem (-10)
a³ + 7a²
- a² - 11a
- a² - 7a
