Answer:
4 and 3, 4 and 5, 3 and 6
Step-by-step explanation:
Those angles make 180 degrees.
Answer:
c) infinite
Step-by-step explanation:
z - y = 12
-3z + 3y = -36
<h3>
simplify the first equation to find z in terms of y</h3>
z - y = 12
<em>add 12 to both sides of the equation</em>
z - y + y = 12 + y
z = 12 + y
<h3>now, substitute z for 12 + y in the second equation.</h3>
-3z + 3y = - 36
-3(12 + y) + 3y = -36
-36 -3y + 3y = -36
-36 = - 36
the answer is infinite solutions, because no matter what y and z are, -36 will always equal -36

1 is 5
2 is 3
3 is 10
so if you put the values you will get 128
Answer:
y = or -3.571
x = or 1.429
Step-by-step explanation:
x - y = 5
x = 5 + y
Solve for y:
y = -6x + 5
y = -6(5 + y) + 5 Substitute x with 5 + y
y = -6(5) - 6y + 5
y = -30 - 6y + 5
y + 6y = -30 + 5
7y = -25
y = or -3.571
Solve for x:
x = 5 + y
x = 5 + -25/7
x = or 1.429
