Answer:
(for the second one)
y = 4x + 10
solution:
so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)
so it will look like
2 - 6/0 - 1
-4/-1
4
so you can now write the equation as
y = 4x + b
now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)
sooo
18 = 4(2) + b
18 = 8 + b
b = 10
so the function for the second one is y = 4x + 10
Using the given discrete probability distribution, it is found that the probability that a randomly selected student has a grade higher than a C is given by:
P(X > 2).
<h3>What is the discrete probability distribution for the grade?</h3>
From the table, it is given by:
- P(X = F) = P(X = 0) = 0.04.
- P(X = D) = P(X = 1) = 0.05.
- P(X = C) = P(X = 2) = 0.17.
- P(X = B) = P(X = 3) = 0.31.
- P(X = A) = P(X = 4) = 0.43.
Grades A and B are greater than C, hence the probability of getting a grade higher than C is given by:
P(X > C) = P(X = A) + P(X = B) = P(X = 3) + P(X = 4) = P(X > 2).

You see the c next to the 27 plug in 2/3 for it so u would get 10(27(2/3)+8)
Answer: -x²+4x-9
Step-by-step explanation:
(g-h)(x) is the same as g(x)-h(x). Since we were given g(x) and h(x), we can subtrac them.
2x-1-(x²-2x+8) [distribute -1]
2x-1-x²+2x-8 [combine like terms]
-x²+4x-9
Now, we know thhat (g-h)(x)=-x²+4x-9.
