Since the graph was not given, answer will be subjective. The graph that shows the solution to the system of linear inequalities of 2x – 3y <12 y < –3 is the one that has It is option B.
<h3>What is linear inequalities?</h3>
A linear inequality is said to be a kind of an inequality that entails a linear function.
Note that a linear inequality is said to be made up of one of the symbols that connote inequality. It is the one that depicts the data that is not equal on a graph.

The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
Your answer should be -50

Answer:
1/5 or 20%
Step-by-step explanation:
The total number of paintings is 60.
60 = x (x − 2) + x + 2x + 8 + 10
60 = x² − 2x + x + 2x + 18
0 = x² + x − 42
0 = (x + 7) (x − 6)
x = -7 or 6
Since x can't be negative, x = 6. So the number of paintings from the 20th century is 6 (6 − 2) + 6 = 30.
The number of paintings that are both British and from the 20th century is 6.
So the probability that a painting from the 20th century is also British is 6/30 = 1/5, or 20%.
