(A) 5x+2y=21
(B) -2x+6y=-34

multiply (A) by - 3→ -15x - 6y = - 63 (C)

Now add (C) to (B):

-15x - 6y = - 63 (C)
-2x + 6y  =-34 (B)
 -----------    --------
-17x         = - 97       and x = 97/17

Now replace x value in any of the equation and you'll find y = - 64/17

1st Answer (97/17 , - 64/17)
2nd Answer : 97/17 + (-64/17) = 97/17 - 64/17 = 33/17 ≈ 2

WILL GIVE BRAINLIST 2 BEST ANSWER
kolezko [41]

Answer:

M

Step-by-step explanation:

We have been given side AB and BC

AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).

BC must be also 6 as it starts at -4 and ends at 2.

Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)

C is the hypotenuse (longest side) and this is what we are trying to find...

6^2 + 6^2 = 36+36=72

So AC is 72, however we need to square root this to get our final answer.

72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...

AC is 6 root 2

Hope this helps!

He starts at -184 ft (since he is below the surface) and then goes up + 53 ft putting him at -131 ft.
-184+53=-131
Then he goes down another -168 feet to -299 ft.
-131-168=-299

So, he is currently at -299ft, or 299 feet below the surface.

Total                                110                            95                             205

54 do not like both hamburgers and burritos

Hence %  = (54/205) * 100  =  26.34 %

marginal relative frequency of all customers that like hamburgers

= 110/205

= 22/41
