Answer:

39

Work:

(x+5)/2=22

We will reverse this equation.

We will start by moving the 2 through inverse operations.

22x2=44

Now we have the equation

x+5=44

We will subtract 5

44-5=39

x=39

the unknown variable equals 39

Kali had 39 CDs on Monday

Write an equation in​ point-slope form of the line that passes through the given​ points, then write the equation in​ slope-inte
frosja888 [35]

As we go from (-6,6) to (9,1), x increases by 15 and y decreases by 5.  Thus, the slope of this line is m = rise / run = -5/15, or m = -1/3.

Point-slope form:  y-6 = (-1/3)(x+6), using data from (-6,6).  

Slope-intercept form:  starting with y = mx + b, substit. -6 for x, 6 for y and -1/3 for m:

6 = (-1/3)(-6) + b, or

6 = 2 + b.  Then b = 4, and the equation in slope-intercept form is

y = (-1/3)x + 4.

Water is pumped out of a holding tank at a rate of 6-6e^-0.13t liters/minute, where t is in minutes since the pump is started. I
astraxan [27]
Procedure:

1) Integrate the function, from t =0 to t = 60 minutues to obtain the number of liters pumped out in the entire interval, and

2) Substract the result from the initial content of the tank (1000 liters).

Hands on:

Integral of (6 - 6e^-0.13t) dt  ]from t =0 to t = 60 min =

= 6t + 6 e^-0.13t / 0.13 = 6t + 46.1538 e^-0.13t ] from t =0 to t = 60 min =

6*60 + 46.1538 e^(-0.13*60) - 0 - 46.1538 = 360 + 0.01891 - 46.1538 = 313.865 liters

2) 1000 liters - 313.865 liters = 613.135 liters

Answer: 613.135 liters

What are the factors of (r+t)(e)
mina [271]

Depending on the values of  'r',  't', and  'e', the numerical value of that expression
might have many factors. 

For example, if it happens that r=5, t=1, and e=4 for an instant, then, just
for a moment,  (r + t)(e) = (5+1)(4) = 24, and the factors of (r+t)(e) are
1,  2,  3,  4,  6,  8,  12, and  24 .   But that's only a temporary situation.

The only factors of (r+t)(e) that don't depend on the values of  'r',  't',  or  'e' ,
and are always good, are  (<em>r + t</em>)  and  (<em>e</em>) .

luda_lava [24]

Answer:

(x+4)^2  Choice A

Step-by-step explanation:

x^2 + 8x + 16

what 2 numbers multiply together to give you 16 and add together to give you 8

1*16 = 16   1+16 = 17  no

2*8 = 16   2+8 = 10  no

4*4 = 16  4+4 = 8  yes


(x+4) (x+4)

(x+4)^2
