In this case, to prove what is required, we must use the Pythagorean theorem to find the diagonal of the square.
If the diagonal of the square is smaller than the diameter of the circle, then the square will fit perfectly in the circle without touching it.
Diagonal = Root ((7 ^ 2) + (7 ^ 2)) = 9.89 cm.
we observed that
9.89cm <11cm.
Therefore we show that:
the square will fit inside the circle without touching the edge of the circle
What the heck the variables are'nt even correct
The graph has a slope of 2 because for every 2 units it rises, it moves to the right 1 unit. We also know the y-intercept is y=4.
So the equation disregarding the inequality is:
y = 2x + 4
Since the area ABOVE the curve is shaded, that means that y is greater than 2x+4. The dotted line means that it is strictly greater than and not equal to.
So now we have y > 2x + 4
We can rearrange our answer to get 4x - 2y < -8 which is the correct answer.
