<span>-2.9x + 5.4y = 140.94
answer is </span><span>y-intercept is 26.1
cause when </span><span>y-intercept x = 0
</span>-2.9(0)+ 5.4y = 140.94
<span>5.4 y = 140.94
y = 140.94 / 5.4
y = 26.1
</span>
As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.

Completing the square gives
At the point on the graph along the axis of symmetry, the squared term vanishes, so that when , we have . So
Answer:
Option 4
Step-by-step explanation:
Given:
Sinθ =
Since, cos2θ = 1 - 2sin²θ
cos2θ =
cos2θ = 1 -
cos2θ =
cos2θ =
Therefore, Option 4 will be the answer.
