SAS because of the vertical angle theorem
Answer:
8 miles
Step-by-step explanation:
24/3 = 8
D.
Just adding these equations results in them being placed in an equation as it appears.
Y + x = -2
y = 1/2x + 7
substitue...
1/2x + 7 + x = -2
1.5x = -9
x = -6
y + (-6) = -2
y-6=-2
y=4
so your final answers are
x = -6 , y = 4
One example is the equation 2x+3x = 5x because the left hand side combines to form the right hand side. This equation is said to be an identity, which is always true for any real number you can think of. For example, if x = 3, then,
2x+3x = 5x
2*3+3*3 = 5*3 ... replace every x with 3
6 + 9 = 15
15 = 15
We end up with a true equation. This will happen regardless of what x value we pick. Therefore, it has infinitely many solutions.
