Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
Answer:
43.2°
Step-by-step explanation:
Just multiply .12 by 360° (the number of degrees in a circle), this will give you the central angle.
Multiplying the decimal means your finding 12.% of 360°
So the angle is 43.2° degrees
First of all, let's find the slope of line L. To find the slope of a line, you write it in the explitic form , and consider the coefficient . So, we have
So, the slope of line L is 2/3.
Two lines are parallel if they have the same slope. So, line M has slope 2/3 as well, and we know that it passes through the point (3, -10).
When you are given the slope and a point of a line, its equation is given by
So, if you plug your values, you have
which you can simplify into
-9 is the answer to this equation
