answer must be rectangle and if the intersection is between then it's a squre
The solution of two equations/lines is their intersect point.
Therefore, there can only be one intersection point/solution, because these lines are neither parallel or identical.
In the graph you can see that they intersect at (x,y)=(2,3) which is your solution and option b or d as one of them seems to be mistyped :)
@question2
y=kx+b
both your equations share the same k=-2:
y=-2x+3
y=-2x-1
therefore these lines are parallel and don't have any intersection as they are always at different y values (the b)
to simplify it, we need to combine like terms. 8 and 15 are like, and 5x and 2x are like. so we rearrange it: 8+15-5x-2x
and now we simplify: 23-7x
Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.
<em>Answer:</em>
<em>It is C</em>
<em>Step-by-step explanation: The explanation says that he subtracted 10 by 20 and divided by 5 so the real answer is 18 but the answer in your page is C </em>
