The solution to the system of equations is (-3, -5) because the point satisfies both equations
<h3>What is a
linear function?</h3>
A linear function is in the form:
y = mx + b
Where m is the slope (rate of change) and b is the y intercept
Line A:
y = x − 2 (1)
Line B:
y = 3x + 4 (2)
Solving both equations simultaneously gives:
x = -3, y = -5
The solution to the system of equations is (-3, -5) because the point satisfies both equations

Answer:
C. 3.4
Step-by-step explanation:
We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.
Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.
Expected value, denoted by E(x), has the formula:
E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct
E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.
The answer is thus C.
