x=3, y=-4

Step-by-step explanation:

First, get either the x or the y variable by itself using one of the given equations:

-4x-4y=4

-4y=4+4x

y=-(4+4x)/4

y=-1-x

Then plug this into all the y variable in the other equation to find x:

4x+5(-1-x)=-8

4x-5-5x=-8

-1x-5=-8

-x=-3

x=3

Then plug this into ever x of one of the equations to find y:

4(3)+5y=-8

12+5y=-8

5y=-20

y=-4

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
