We had that question a few times already; here's a link:

https://web2.0calc.com/questions/help_54234#r3

Start with the lower 2 that forma 180 degree straight line:

5x+45    +    3x-25      =  180     solve for 'x'

THEN: Sustitute in the value of 'x'   to find y     :        y  +     2x-5    +   3x-25      = 180      

26*25*24*23=358800

The plot has a positive slope and very tight pattern is nearly a 1 to 1  line

   so I would say a STRONG POSITIVE RELATIONSHIP

114 - 45 + 1 = 70 terms

1 - [45 + 114] / 2 * 70 =

2 - 159/2 * 70 =

3 - 79.50 * 70 =5,565 - steps 1, 2, 3 is the "Gauss's Method"

26 choices for first letter

   25 choices for second letter

       24 choices for third letter

           23 choices for last letter

26  x  25  x  24  x 23 = ........... choices

and the middle two digits cannot be a 6   

That's interesting.  My SSN is xxx - 68 - xxxx

Several ways to proceed,  here is one way

perpindicualr slope = -2

find perpindicular line with the given point

2 = -2(6) + b

b =14

y = -2x+ 14            equating the two line equations yields an intersection point : 3.6, 6.8

    moving the same horizontal distance from this point as from 6,2 TO this point yields   x = 1.2

Here is a graph to visualize this:

https://www.desmos.com/calculator/w0o35tr6mb

x ≤ -2

rate = acres/time

2 acres / 1 hour   +  3 acres / 2 hours =  14 acres / x hours

2/1 + 3/2 = 14/x

7/2 = 14/x

x = 14 * 2/7 = 4hours   for both working

Another way to look at it:

With both of you working , you can mow  3.5 acres each hour

14 acres / (3.5 acres/hr) = 4 hours

1025 , 1035 , 1045 , 1205 , 1230 , 1235 , 1240 , 1245 , 1250 , 1305 , 1320 , 1325 , 1340 , 1345 , 1350 , 1405 , 1420 , 1425 , 1430 , 1435 , 1450 , 1520 , 1530 , 1540 , 2015 , 2035 , 2045 , 2105 , 2130 , 2135 , 2140 , 2145 , 2150 , 2305 , 2310 , 2315 , 2340 , 2345 , 2350 , 2405 , 2410 , 2415 , 2430 , 2435 , 2450 , 2510 , 2530 , 2540 , 3015 , 3025 , 3045 , 3105 , 3120 , 3125 , 3140 , 3145 , 3150 , 3205 , 3210 , 3215 , 3240 , 3245 , 3250 , 3405 , 3410 , 3415 , 3420 , 3425 , 3450 , 3510 , 3520 , 3540 , 4015 , 4025 , 4035 , 4105 , 4120 , 4125 , 4130 , 4135 , 4150 , 4205 , 4210 , 4215 , 4230 , 4235 , 4250 , 4305 , 4310 , 4315 , 4320 , 4325 , 4350 , 4510 , 4520 , 4530 , 5120 , 5130 , 5140 , 5210 , 5230 , 5240 , 5310 , 5320 , 5340 , 5410 , 5420 , 5430 , Total =  108 such numbers.

Beginning with each of the 4 numbers, 1, 2, 3, 4, each number begins with 4! =24 permutations. 24 x 4 = 96 permutations. Beginning with 5 itself, ordinarily you would also have 4! or 24 permutations, but because you cannot have 2 "fives" in the same permutation, then we can only have: 24/ 2 = 12 permutations beginning with 5.

So: 96 + 12 = 108 such numbers.

                          6                    

 7 sqrt5  + 15 sqrt5  + 12 sqrt5

                          6                   

                  34 sqrt 5

3* sqrt5/85  

101/500  =  .202

y = 1/3 x +4     slope , m , = 1/3   perpindicular slope  = - 1/m = -3

(y-8) = -3 (x-5)                re-arrange to any form you want

sin x = - 0.73   between 0 and 360^o

arcsin ( - 0.73) =   313.11^o   and    226.89^o

The 'x' coordinate will be   - b/2a   =  - -64/16 = 4

the 'y' coordinate will be       8 ( 4)^2  - 64(4) = -128     ( found by substituting '4' into the equation for 'x')

Slope = 1/4     (both lines)

y = 1/4 x + b     sub in the given point ot calc 'b'

3 = 1/4 ( -8) + b

 b = 5

y = 1/4 x + 5

As follows:

8 x 10 x 10 x 9 x 9 x 10 x 10 x 10 x 10 = ........

a + 5b = 17.

You can write 1, 2, 3, ..., 100.

There are four solutions.

What...is this?

Wow....that is not even a SLIGHT typo!   .
