Step-by-step explanation:
P(C) = 4/10 = 2/5
P(A) = 6/10 = 3/5
The y-intercept (where the line hits the y-axis) will move from (0, 1/2) to (0, -2)
Answer: First option is correct.
Step-by-step explanation:
Since we have given that

Now, by factorising , we get

Now, we use the formula i.e.

By using this, we get ,

So,

There is only one solution to the equation. A quadratic equation has 2 solutions a positive and a negative, but since we are looking for length, the answer can only be postive. Area= side^2
400= x^2
sqrt(400)=x
20 inches = x
The length of one side is 20 inches
check: 20*20 = 400, which is the area of the square painting.
