Write the slope-intercept form of the equation of the line through the point (-1,-5) with a slope of 5/6.
Answer:
5/6x+4 1/6=y
Step-by-step explanation:
The equation to find a slope-intercept is mx+b=y
m=slope
x=x coordinates
y=y coordinates
b= y intercept
m=5/6
x=-1
y=-5
b=4 1/6
Y intercept:
5/6(-1)+b=-5
-5/6+b=-5
b=4 1/6
However, it asks for an equation of the line, not (-1,-5), so we only need to write m and b, but not x and y.
So: 5/6x+4 1/6=y

Enter the correct answer.
The y-intercept of the graph is -3
How to find the y-intercept of a graph?The y-intercept is the point where the line intersects the y-axis. This is the value of y when x is equals to zero.
Using slope intercept formula,
y = mx + b
where
m = slopeb = y-interceptNow, let's trace the value of y when x = 0 in the graph.
Therefore,
when x = 0, y = -3
Hence, the y-intercept of the graph is -3

Write a system of equation for the following scenario.
Roshaun has saved $150 and continues to save $10 each week. Keegan starts with $0 and saves $25 each week.
Answer:
Let's start out with the amount of money each person will have over any period of time. Let t = time in weeks.
Roshaun will have 150 + 10t. Keegan will have 25t. we want to know when they will have the same amounts, so we set the 2 equations equal and solve for t:
150 + 10t = 25t
150 = 25t - 10t
150 = 15t
150/15 = t
10 = t
Therefore, in 10 weeks they will both have the same amount:
Roshaun: 150 + 10(10)--->150 + 100 = $250
Keegan; 25(10) = $250

Elvira, the cafeteria manager, has just received a shipment of new trays with the school logo prominently displayed in the middle of the tray. After unloading 4 cartons of trays in the pizza line, she realizes that students are arriving for lunch and she will have to wait until lunch is over before unloading the remaining cartons. The new trays are very popular and in just a couple of minutes 24 students have passed through the pizza line and are showing off the school logo on the trays. At this time, Elvira decides to divide the remaining trays in the pizza line into 3 equal groups so she can also place some in the salad line and the sandwich line, hoping to attract students to the other lines. After doing so, she realizes that each of the three serving lines has only 12 of the new trays. "That's not many trays for each line. I wonder how many trays there were in each of the cartons I unloaded?"
Help the cafeteria manager answer her question using the data in the story about each of the actions she took. Explain how you arrive at your solution.
Answer:
im willing to bet that there is 3 in each carton
(just a guess for the points also theres no multiple choice?)
The quantity of trays that were in each of the cartons the manager unloaded was 12 trays.
How many trays there were in each of the cartons I unloaded?To determine the quantity of trays in each carton, we need to analyze the given information step by step:
We know that 24 students have passed through the pizza line and received trays with the school logo.The remaining trays were divided into three equal groups for the salad line, sandwich line, and pizza line.Each serving line ended up with only 12 new trays.From these points, we can deduce the following:
Since 24 students passed through the pizza line, and each student received one tray, this means that 24 trays were taken from the initial shipment.After 24 trays were taken, an equal number of trays were distributed to the salad line, sandwich line, and the remaining trays were kept in the pizza line.Each serving line ended up with 12 new trays. Since the trays were divided equally among the three lines, each line received the same number of trays.Now, let's solve for the number of trays in each carton.
Let's assume that the number of trays in each carton is "x."
We know that 24 trays were taken initially, and each serving line ended up with 12 trays. So, we can set up the equation:
24 + 12 + 12 + 12 = 4x
48 = 4x
Dividing both sides of the equation by 4:
12 = x
Therefore, there were 12 trays in each of the cartons that were unloaded.
To summarize, each carton that Elvira unloaded contained 12 trays.

Answer:
So, f(x) = 6 x + 30; 0 ≤ y ≤ 4
Step-by-step explanation:
Given: A lawn-mowing company had 30 clients when they started its business and wants to increase by 6 new clients each week.
To find: arithmetic sequence to write a function to represent the real-world situation and the range of the function for the first four weeks of data.
Solution:
A sequence is a list of numbers in a specific order following some pattern.
A sequence is said to be arithmetic if difference between the terms is same.
For the first week, number of clients = 30
For the second week, number of clients = 30 + 6(1)
For the third week, number of clients = 30 + 6(2)
For the third week, number of clients = 30 + 6(3)
For the fourth week, number of clients = 30 + 6(4)
So, f(x) = 6 x + 30; 0 ≤ y ≤ 4
