(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6

y = mx + b
slope(m) = -0.6
use either of ur points (0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b

so ur equation is : y = -0.6x + 346

after 4 weeks....x = 4
y = -0.6(4) + 346
y = -2.4 + 346
y = 343.6 <=== after 4 weeks it will be 343.6

When determining intercepts algebraically what does it mean if you get an imaginary solution?
mr_godi [17]
When determining intercepts algebraically and you get an imaginary solution, this would mean that the graph of the function does not pass through the x or the y axis. X-intercept is the value of x when y would be equal is zero or the value x when the graph passes/ intersects the x-axis. On the other hand, the y-intercept is the value of y when x is zero or the value of y when the plot intersects the y-axis. Therefore, the value of these intercepts should be real values and not imaginary numbers or else these intercepts do not exist. The plot of the equation would not cross any of the axes in the coordinate.

Directions: Solve each equation. Show<br> -26 = -9x + 10<br><br> What is the answer?
Ymorist [56]

Answer:

-26= -9x + 10

-26 - 10= -9x

-36=-9x

-36:(-9)=x

4=x

Step-by-step explanation:

1. you pass +10 to the left in minus

2. you resolve what you've got on the left

then you pass the multiplying -9 to the left dividing

You own a company that employs three salespeople, Quentin, Michael and Bubba. Quentin makes 30% of the sales, Michael 45%, and B
borishaifa [10]

Answer:

Michael

Step-by-step explanation:

Look at the table below:

The probability of selecting a sale that was made by Quentin is .30, by Michael is .45 and by Bubba is .25.

Since Quentin completes paperwork 90% of the time, he doesn't complete paperwork 10% of the time, following this reasoning we can say that Michael doesn't complete paperwork 20% of the time and Bubba doesn't complete paperwork 15% of the time.

The probability of selecting a file and that it belongs to Quentin AND is incomplete is:

(Probability of selecting a Quentin's file) x (Probability is a Quentin incomplete file) = (0.30)(0.10) = 0.03

Using this same method we have that the probability that it belongs to Michael and is incomplete is (.45)(.20) = 0.09

That it belongs to Bubba and it's incomplete is (0.25)(0.15) = 0.037

The highest of these probabilities is the one that corresponds to Michael: 0.09, therefore he is the most likely culprit.

An experienced landscaper can landscape garden with an area of 60sq.m thrice as fast as an apprentice. Working together, it take
Genrish500 [490]

Answer:

It will take the apprentice 24 days working alone

Step-by-step explanation:

Let the number of days it takes the apprentice be x

It will take the landscaper x/3 ( since he is three times faster)

The rate for both will be 60/6 = 10 sq m per day

Rate for apprentice is 60/x

rate for the boss is 60/x/3 = 180/x

Adding the rates together;

60/x + 180/x = 10

240/x = 10

240 = 10x

x = 240/10

x = 24 days
