If it's parallel to the y axis this means the slope will be any number over 0 with means it's D undefined
Yes the answer is C. -2 to the left with open circle and 4 to the right with closed circle
Answer:
See explanation
Step-by-step explanation:
(4)
Using the sine ratio in the right triangle
sinΘ = = , thus
Θ = () ≈ 51.1°
(5)
Using the tangent ratio in the right triangle
tanΘ = = , thus
Θ = () ≈ 38.7°
Write the 2 equations:
5x-2y=18
-5x+3y=-22
You can see that the coefficients of x are opposites, so you can add them(the 2 equations) to eliminate x.
Adding them, you get:
y=-3
So now that you know y, you can substitute the value of y into one of the original equations. Let's substitute it in the first one:
5x+6=18
Solving this, we get:
5x=12
x=12/5
x=12/5, y=-3
The answer is 7/1, when you want to know a reciprocal, all you do to the fraction is flip it around. Hope this Helps!
