DON'T LISTEN TO THE ANSWERS ON HERE, THEY'RE WRONG!!!!
Step-by-step explanation:
angle 4
110-180
=70
angle 5
angle = 110
angle 6
110-180=
70

Y = 2x - 3 --------- (1)
y = 4x + 1--------- (2)
---------------------------------
Equation (2) - (1) :
---------------------------------
(y - y) = (4x + 1) - (2x - 3)
0 = 4x + 1 - 2x + 3 // remove brackets
0 = 2x + 4 // combine like terms
2x + 4 = 0 // switch sides
2x = -4 // take away 4 from both sides
x = -2 ------ sub into (1) // Divide by 2 on both sides
y = 2(-2) - 3 // Sub x = -2 into equation (1)
y = -4 - 3 // Remove bracket
y = -7 // Combine like terms
-----------------------------------
Answer: x = -2, y = -7
-----------------------------------
For this case we must simplify the following expression:
By law of multiplication signs we have to:
We add similar terms:
We simplify:
Answer:
The answer is 7
7^2 equals 49
The reason is because 7x7=49
