Penske   cost  = 49.95  + .59 x        x = miles

U-Haul    cost = 39.95   + .99 x        x = miles

b  set the above equations = to each other and solve for x

        if you drive x miles the two trucks are same price

        less than x miles means U-Haul is cheaper

        more than x miles Penske costs less

steeper graph will have the bigger 'x' coefficient  : Uhaul @ 99

(6 x 9 )  + 6 + 9

   54     + 6   + 9 = ..........

1 / sqrt2   +   3 / 2sqrt2   +  5 / 4sqrt2

4 / 4sqrt2   + 6/ 4sqrt4    + 5/ 4sqrt2           can you finish?

the job remaining is 1/3 pail of potatoes

Pippin will require  50% more time to go from 2/3 to  3/3    or  15 minutes

Peter by himself could do the 1/3 pail  in 10 minutes

1/10 + 1/15 = 1/x     solve for x = 6 minutes

In the form y = mx+b, m is the slope. So it's -1

-1,

you can just graph it

First, convert into vertex form by first foiling (x+7) and (2-x), which turns the equation into  \(4(-x^2-7x+2x+14)\) = \(4(-x^2-5x+14) = -4x^2-20x+56\). Then, use -b/2a to find the x-coordinate of the vertex \(20 \over 2*-4\)=-5/2. Then, just plug -5/2 into the equation to get the y-coordinate. The vertex in this case is the maximum of because the leading coefficient is negative for a quadratic equation.

1 - Figure out the number of days between July 27 and Sept. 3, 2008, including BOTH birthdays = 39 days.

2 - Figure out the number of years from 2008 to 2021 =2021 - 2008 + 1 =14 years.

3 - Multiply: 39 days  x  14 years =546 Cake-eating days !!!

Can you repeat the letters such as: PPP,  AAA,   FFF.....and so on?

Here is my attempt at your question:

2 dozen =24 cupcakes. Since 2/3 is the largest fraction, which means: 2/3  x  24 =16 cupcakes that contain raisins. Since 1/2 x 24=12 that contain chocolate, could theoretically be included in the 16 cupcakes that contain raisins, since it does not preclude it! The same reasoning could be applied to the 1/4 x 24 =6 cupcakes that contain chocolate chips could be included in the 16 cupcakes that contain raisins as well. The same goes for the last 1/8 x 24 = 3 cupcakes that contain nuts could also be included in the 16 cupcakes that contain raisins as well!!

So, the conclusion is that the 2/3 x 24=16 could theoretically contain all FOUR ingredients of chocolates, raisins, chocolate chips and nuts. Which means: 24 -16 = 8 Is the largest possible number of cupcakes that have NONE of the 4 ingedients.

4(3х+2)-7(х+1)=3(х-1)      expand

12x + 8    - 7x-7    =  3x - 3       simplify

(12x - 7x-3x)  = -8 +7 -3

2x = -4

x = -2

Use Quadratic Formula :

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)           a = 2     b = -3    c = 27

This will give you the two roots....then you can add them....  I'll tell you the imaginary parts :   +-   3/4 * i sqrt (23)

1) if b = -1/2   when yo add the two polynomials together the   ^{4   and the  2}  dgrees 'cancel out'   and you are left with degree of one ;     x¹

Thx. I graphed the parabola and plugged in values for m.

y=x^2+2

y=-3x^2=1

And solved.

Hope im on the right track thx

y = kx       k = proportionality constant

16 = k (8)            k = 2

Was there more to the Q ?

Your numbers don't 'work' ....  if 26 brought water bottles....how can 28 have brought water bottles and yoga mats ?

Just use this website calc

2.17

Or more properly: 9.10938  x  10^-31 kg - mass of electron

4.5 is rounded already     the ' .5 ' portion is the 'tenth'    ....without a digit after the 5  you cannot do anything more with this.

9.1  x  10^-31 kg in scientific notation

7.3  x  10^22 Kg - in scientific notation.

I do not have time to present this properly and maybe getting an outline is better anyway..

First, draw a rough sketch, this will be enough to tell you that y must be greater than 2.  It will also tell you that there is only one y value (but 2 x vales for the solution.)

second, Solve the 2 equations simultaneously, (for y)

y will be in terms of m but if you know roughly what it looks like you will know that there is only one solution.

So the discriminant must be 0.  

From this, the value of m can be determined.

You are welcome to ask questions (tell me what you have done though)

Let the number of ounces of 20% medicine needed =T

Then, the number of ounces of 5% medicine needed =10 - T

0.20T  +  0.05*[10 - T] =0.08 * 10, solve for T

T = 2 ounces of 20%medicine needed

10 - 2 = 8 ounces 0f 5% medicine needed.
