Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
Answer:
Step-by-step explanation:
Start by moving the 3 to the other side of the equals sign to get

so with that replacement:

By the Zero Product Property,
or 
Yes these are both the same, so we only need one of them. Once we find the angle, they are both the same, so we only need one of these equations.
If
, take the inverse tangent of both sides to give you:
and
so

Tangent increases in increments of pi or 180, so the other angle within the given interval is 35.8 + 180 = 215.8
Answer:
X=50°
Step-by-step explanation:
Let, the fourth angle in the quadrilateral be ∠A
The sum of all the four angles of the quadrilateral is 360°
So 40° + 110°+80°+∠A=360°
230°+∠A=360°
∠A=360°-230°
∠A=130°
The fourth angle of the quadrilateral is 130°
The angle A and X are the angles on a straight line
The sum of the angles on a straight line is 180°
so, ∠A+∠X=180°
130°+∠X=180°
∠X=180°-130°
X=50°
Answer:
well they are each a part of each other on numerator is 10 because 10 across
the other is 3 because its 3 down. right?
Step-by-step explanation:
Answer:
Step-by-step explanation:
½(x-2) = 8 + 5x
Multiply both sides by 2
2⋅½(x-2) = 2(8 + 5x)
1(x-2) = 2(8 + 5x)
Apply the distributive rule
x - 2 = 16 + 10x
Subtract x from both sides
-2 = 16 + 9x
Subtract 16 from both sides
-18 = 9x
Divide both sides by the coefficient of x
-18 ÷ 9 = 9x ÷ 9
-2 = x
