Because both of the polygons are congruent and are flipped so there for they are the same angle
Step-by-step explanation:
-5 + 2 - 8 - (-14) =
(-3) - 8 + 14 =
-11 + 14 =
3 =
not sure but here you go^^
Answer:
15
Step-by-step explanation:
a square root multiplied by itself equals the number inside the box, right?
(/~15~)2 = 15
The pair of equations:
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)
