Y = x² + 3 just put where it belongs to see which one is a solution to it.
10 = -3² + 3 (-3, 10)
10 = 9 + 3
10 = 12 not a solution because it doesn't equal the same in both sides.
8 = 2² + 3 (2, 8)
8 = 4 + 3
8 = 7 not a solution.
12 = 3² + 3 (3, 12)
12 = 9 + 3
12 = 12 a solution.
22 = 5² + 3 (5, 22)
22 = 25 + 3
22 = 28 not a solution.
so your answer is (3, 12).
hope this helps, God bless!
Answer:
In this question we have to use the formula of simple interest, which is
I = P r t
Where I is the interest earned, P is the amount invested, r is the rate of interest and t is the time duration .
In the given question, I = $4840 , r =11% or 0.11, t=11, P is unknown .
Substituting the values in the formula, we will get
P=4000
So she invested $4000.
