The measures of 2 vertical angles are always equal, so we have:
7x+182=9x+192.
Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.
Thus, x=-6.
This means that the angles are:
i) 7x+182=7(-6)+182=182-42= 140(degrees).
ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)
Answer: x=-6</span>
Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3
Answer:
x=6-2y
Step-by-step explanation:
3x+6y=18
Subtract 6y from both sides of the equation.
3x=18−6y
Divide each term by 3 and simplify.
Divide each term in 3x=18−6y.
3x/3=18/3+−6y/3
Cancel the common factor of 3.
x=18/3+−6y/3
Simplify each term.
x=6−2y

Answer:
1/2x
Step-by-step explanation:
To solve this type of fraction you need to times the inverse of the bottom fractal, both over and under. In this case the inverse of 1/2 is 2/1
