What is the equation in point-slope form of the line that passes through the points (7, 5) and (-4, -1)
Answer:
y - 5 = (-6/11)(x - 7)
Step-by-step explanation:
Looking at the points (7, 5) and (-4, -1), we see that x decreases by 11 (from 7 to -4) and y decreases by 6 (from 5 to -1). Therefore, the slope of this line is m = rise / run = -6 / 11.
Start with the point-slope form y - k = m(x - h). Substitute the x- and y-coordinates of one of the given points for h and k in the above form:
y - k = (-6/11)(x - h) => y - 5 = (-6/11)(x - 7)
This is the equation of the line in question, in point-slope form.

The function y=5x+10 represents the total cost y of a group of x members to go paintballing.
What do the independent and dependent variables represent?
Answer:
The independent variable (x) represents the members to go paintballing.
The dependent variable (y) represents the total cost.
Step-by-step explanation:
The y is always dependent on the x. The number of people attending affects the total cost of the trip. The more people attend, the more it costs.

Using measures of center and variability to compare data- quiz answers?
herehopes it helps can i pleaseget brainliest
Answer is YES.
Steps for Comparing a Data Set by Measures of Center & Variation:
Measure of center: a value that describes the center of a set of data. Measures of center include the mean, median, and mode.
Measure of variability: a value that describes how spread out numbers in a data set is. Measures of variability include the range and mean absolute deviation.
Step 1: Calculate the measure of center/variation for each set of data.
Step 2: Compare the two measures of center/variation based on the problem.
Here, we can use both to compare data - quiz answers.

Step 1: Take 7 away from 23. You will then get 16.
Step 2: Divide 16 by 2. Your answer will then be 8.
8 will end up being Ted's age.
Step 3: Add 7 to 8. Once you do this, you will get Henry's age.

Jocelyn has 400 pounds of chemical A that she must react with 200 pounds of chemical B to create chemical C for use in an industrial manufacturing process. How many pounds of chemical C will Jocelyn have after the reaction is complete?
Answer This chemical reaction should follow the Law of Conservation of Mass where mass cannot be created nor destroyed. That is, what goes in a system should be equal with what goes out the system. For this problem, the mass of C that is produced assuming there are no by-products should be 600 pounds.
Step-by-step explanation:
Jocelyn will have 600 pounds of the chemical (C) after the reaction is complete

for an infinite queuing situation, if the arrival rate for loading trucks is 5 trucks per hour, what is the mean time between arrivals?
Using proportions, it is found that the mean time between arrivals is of 12 minutes.
This question is solved by proportions, using a rule of three.In one hour(60 minutes), 5 trucks arrive, thus what is the time necessary for 1 truck to arrive?The rule of three is:
5 trucks - 60 minutes
1 truck - x minutes
Applying cross multiplication:
[tex]5x = 60[/tex]
[tex]x = \frac{60}{5}[/tex]
[tex]x = 12[/tex]
