Answer:
Step-by-step explanation:
Simplifying
4x + 2y = 18
Solving
4x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
4x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
4x + 0 = 18 + -2y
4x = 18 + -2y
Divide each side by '4'.
x = 4.5 + -0.5y
Simplifying
x = 4.5 + -0.5y
////////////
Simplifying
y = -2 + 9
Combine like terms: -2 + 9 = 7
y = 7
Solving
y = 7
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 7
I don’t think you can calculate the arc without the radius. All I know is that the angle is 110 degree
55 increased by 209%
Since we are increasing by 209% ,
New value would be = 100% + 209% = 309% of the old value which is 55.
= 309% * 55
= (309/100) * 55
= 3.09 * 55 = 169.95
The result is 169.95
<span>3x²-9x is a binomial, so if you divide it by 3x, the quotient will also be a binomial:
</span><span>3x²-9x
--------- = x - 3 (answer)

18) Value of b is : 
Option A is correct.
19) Option C is correct.
Step-by-step explanation:
18) We need to find the value of b.
The given equation is:

Solving to find the value of b:

So value of b is : 
Option A is correct.
19) We need to find the correct graph of the equation:

Solving:

The values of y will be less than three. As y < 3 so, the circle on y is not filled.
So. Option C is correct.
