Anyone know 14!!!!! Please help me!!!!!:(
asambeis [7]

-- They're losing employees . . . so you know that the line will slope down, and
its slope is negative;

-- They're losing employees at a steady rate . . . so you know that the slope is
the same everywhere on the line; this tells you that the graph is a straight line.

I can see the function right now, but I'll show you how to go through the steps to
find the function.  I need to point out that these are steps that you've gone through
many times, but now that the subject pops up in a real-world situation, suddenly
you're running around in circles with your hair on fire screaming "What do I do ? 
Somebody give me the answer !".

Just take a look at what has already been handed to you:

0 months . . . 65 employees
1 month . . . . 62 employees
2 months . . . 59 employees

You know three points on the line !

(0, 65) ,  (1, 62) ,  and  (2, 59) .

For the first point, 'x' happens to be zero, so immediately
you have your y-intercept !    ' b ' = 65 .

You can use any two of the points to find the slope of the line.
You will calculate that the slope is negative-3 . . . which you
might have realized as you read the story, looked at the numbers,
and saw that they are <u>firing 3 employees per month</u>.
("Losing" them doesn't quite capture the true spirit of what is happening.)

So your function ... call it ' W(n) ' . . . Workforce after 'n' months . . .

is           <em>W(n) = 65 - 3n</em> .

Sin^2x + sin2x +2cox^2x = 2
Effectus [21]

Answer:

Step-by-step explanation:

sin^2 \ x + sin ^2 \ x + 2cos^ 2\ x = 2\\\\2sin^2 \ x  + 2 cos^2 \ x = 2\\\\2 ( sin^2 \ x + cos^2 \ x ) = 2 \\\\2 \times 1 = 2 \\\\2 = 2 \\\\LHS = RHS \\\\Hence \ proved.

Solve each system by substitution.<br> 5) 5x + 3y =-23<br> y = 4
docker41 [41]

Answer:

(- 7, 4 )

Step-by-step explanation:

Given the 2 equations

5x + 3y = - 23 → (1)

y = 4 → (2)

Substitute y = 4 directly into (1_

5x + 3(4) = - 23, that is

5x + 12 = - 23 ( subtract 12 from both sides )

5x = - 35 ( divide both sides by 5 )

x = - 7

Solution is (- 7, 4 )
