ElectricPavlov Why are you just ignoring me? I have tried to talk to you but I get no dang response, why? 😔😭~Hannah

CPhill already answered to the same one before here it is:

The points  ( 2,0)  and (0, -4)  are on the line

Slope  of line =  (-4 - 0) / ( 0 -2)  =  -4/-2   = 2

Equation of line  (using 0,-4)  is

y= 2x  -4

Since we have an solid line  the inequality is either

y ≤  2x - 4                  or  y  ≥  2x - 4

Note  that (3,1)  is in  the yellow region

If  we test  this point in both inequalities, note  that

1 ≤ 2(3)  - 4

1 ≤  6 - 4

1 ≤ 2  is true

So....the  correct  inequality is  y ≤  2x - 4 

The shaded area is everything less than and INCLUDING the line ....    find the equation of the line to be

y = 2 x -4

shaded are is thus    y <= 2x-4

Ur  Welcome   !!!

We  have  90 *89   possible outcomes  (some   are the same)  =  8010 possible outcomes

The two-digit multiples  of 5  are

10   15   20   25  30 35 40  45  50  55  60  65   70  75  80  85   90  95    =  18 total

The only  way  to get  a multiple of  5  is either

!) choose one of  these multiples of  5 and  any other two-digit number that isn't a multiple of 5 =

(18)  ( 89  - 17 )  = (18)  (72)  =  1296   possibilities 

2) choose  any two of  the multiples of 5  = C(18,2)   =  153  possibilities

So...the probability of  a  multiple of 5  is    (  1296+ 153) / 8010  ≈  .18  =  18%

You're welcome ...........

   sum of their ages / 3 = 20  

sum of their ages = 60

then add 18 to the sum  ( 6+6+6)

= 78

Thanks a lot!

y = -3/7 x + 18     <===== given 

         x intercept occurs when y = 0

0 = - 3/7 x + 18

  x = 18 / (3/7)  = 42      x intercept = 42

pls help the answers that were attempted were not write and please have explanation thx

If they are perpindicular , then the slope, m of line 1   will be   - 1/m of the second line...

   re-arrange the equations into   y = mx + b form to easily see the slopes

2y + x + 3 = 0   becomes

y = - 1/2 x - 3/2      slope , m = - 1/2     does the slope of the other line = - 1/ (-1/2) = 2 ???

second line

3y + ax + 2 = 0

3y= - ax - 2

y = - a/3 x - 2/3       to be perpindicular    - a/3 must equal 2

                                        - a/3 = 2

                                            a = -6

A is... Never mind you got someone else that is about to answer :/

Bye~Hannah

OOOOOHHHH i know

(Give your answer in the form $ax+by+c>0$ or $ax+by+c\geq0$ where  a,b andc  are integers with no common factor other than 1.)

The probability is pi/6.

What in the world? I believe you, but the site says they are both wrong. Maybe bc of format?

Thanks!

x + xy^2  =  250y

x - xy^2  = -240 y

Add these  and  we  get  that

2x  = 10y

x  = (10/2) y  =  5y

Sub this  into the  first equation and  we  get

5y + (5y)y^2  = 250y

5y^3 - 245y  =  0

y^3  - 49y  = 0

y ( y^2  - 49)  = 0

y (y + 7) ( y - 7) =  0

Setting all three factors to 0 and solving for y  gives us that

y= 0   and x =5(0) =  0

y = -7  and x = 5(-7)  = -35

y =7  and x =5(7)  = 35

So....the solutions are  ( x,y)  = (0,0)   (-35 , -7)   and (35 , 7)

Here's the  graph of  y >  x + 1

Okay I'm pointing out my mistake. That is wrong 

I dont know the correct answer 

So sorry (embrassing)~Hannah

Second one

The points  ( 2,0)  and (0, -4)  are on the line

Slope  of line =  (-4 - 0) / ( 0 -2)  =  -4/-2   = 2

Equation of line  (using 0,-4)  is

y= 2x  -4

Since we have an solid line  the inequality is either

y ≤  2x - 4                  or  y  ≥  2x - 4

Note  that (3,1)  is in  the yellow region

If  we test  this point in both inequalities, note  that

1 ≤ 2(3)  - 4

1 ≤  6 - 4

1 ≤ 2  is true

So....the  correct  inequality is  y ≤  2x - 4 

There total age now is 38.

20+6+6+6=38

Sorry if it's incorrect (I'm not that smart)~Hannah

Sorry.... I dont think you're right... 

Yay! UWU

So glad it helped!~Hannah
