6x + 8y = -22 and Ox + y = -5 *

one solution : (-9 ; 4)

Step-by-step explanation:

hello :

the system is : 6x + 8y = -22 (*)

                       x + y = -5 (**)

by (**)    y= - x -5

put this value in (*) :  6x+8(-x-5)=-22

6x-8x-40 = -22

-2x=18

x= 18/-2

x= -9

put this value in (**) : -9+y=-5

y=4

one solution : (-9 ; 4)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
