Answer:
Step V: Transitive property of Inequality
Step VI: Subtraction Property of Inequality
Step-by-step explanation:
In Step IV, the RHS of t=both the sides are equal.
So, they equated the LHS of both the sides.
This is the transitive property of equality which states that if a = b and c = b then a = c.
In this case, a = 
b = 180⁰
c = 
Consequently, 
In step VI, 
is subtracted on both the sides. So, this is called as Subtraction Property of Equality.
Answer:
x = 0
y = 1
Step-by-step explanation:
I'm on a school laptop so the pic is blocked, i can not seeee.
Answer:
y = -x + 1
Step-by-step explanation:
eqn of line: y=mx+c
perpendicular, m1 x m2 = -1
m × 1 = -1
m = -1
y=-x+c
sub x=-5, y=6
6 = -(-5) +c
6 = 5 + c
c = 1
y = -x + 1
Answer:
-(4x + 7)/2 - (3x - 2)/2 = (-4x - 7 - 3x + 2)/2 = (-7x - 5)/2
Here are my answers to the given questions above:
Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2.
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.
