A graph shows the solutions to be
.. x = -3
.. x = 1
Here's an analytic solution.
.. f(x) = g(x)
.. -2x = x^2 -3 . . . . . . substitute the given function definitions
.. 0 = x^2 +2x -3 . . . . add 2x
.. 0 = (x -1)(x +3) . . . . . factor
Use the zero-product rule to find values of x that are solutions. One or the other of the factors must be zero for the product to be zero.
.. x -1 = 0 . . . . first factor is zero
.. x = 1
.. x +3 = 0 . . . second factor is zero
.. x = -3
Answer:
2/75
Step-by-step explanation:
6 of the 30 pens are green, so the probability of selecting a green pen is 6/30 = 1/5.
The pen is then replaced, so there are still 30 pens in the drawer. 4 of the pens are black, so the probability of selecting a black pen is 4/30 = 2/15.
The probability of both events is therefore 1/5 × 2/15 = 2/75.
The decimal that represents the amount he harvested, is 0.06 because 3/50 is equivalent to 0.06 acres of corn crops.
Answer:
5^3 = 125
Step-by-step explanation:
Steps:
5^3 = 5 × 5 × 5
= 125
I think it’s
y=2/3+21
