Step-by-step explanation:
Here you just have to assume values for x and plug them to find f(x).
first column "x" is the values you will assume.second column is the plug in process.third column is the final result for each x plugged in an equation.4) f(x) = 6x - 4
we will assume for each equation 4 values of x: -1, 0, 1, and 2.
x = -1 --> f(-1) = 6(-1) - 4 = -10
x = 0 --> f(0) = 6(0) - 4 = -4
x = 0 --> f(1) = 6(1) - 4 = 2
x = 0 --> f(2) = 6(2) - 4 = 8
5) f(x) = 5 - 2x
Again, we will assume for each equation 4 values of x: -1, 0, 1, and 2.
x = -1 --> f(-1) = 5 - 2(-1) = 7
x = 0 --> f(0) = 5 - 2(0) = 5
x = 0 --> f(1) = 5 - 2(1) = 3
x = 0 --> f(2) = 5 - 2(2) = 1
6) f(x) = 7 + 3x
Again, we will assume for each equation 4 values of x: -1, 0, 1, and 2.
x = -1 --> f(-1) = 7 + 3(-1) = 4
x = 0 --> f(0) = 7 + 3(0) = 7
x = 0 --> f(1) = 7 + 3(1) = 10
x = 0 --> f(2) = 7 + 3(2) = 13

D) 12(14x+3)+8x–3
Answers
Answer:
b and c I think
Step-by-step explanation:
The expressions 11(x+3) and 8(x+2)+3x+17 are equal to 11x+33 which is the correct answer would be an option (B) and (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
We have to determine expressions which is equivalent to 11x+33
Option A: 9x+12–2x+21 is incorrect because this expression simplifies to 7x+33, which is not equal to 11x+33.
Option B: 11(x+3) is correct because this expression simplifies to 7x+33, which is equal to 11x+33.
Option C: 8(x+2)+3x+17 is correct because this expression simplifies to 7x+33, which is equal to 11x+33.
Option D: 12(14x+3)+8x–3 is incorrect because this expression simplifies to 168x+36, which is not equal to 11x+33.
Hence, the correct answer would be an option (B) and (C).

Answer:
y = 2x
Step-by-step explanation:
Take two random points on the line. I'm going to take (1, 2) and (2, 4) for this.
Use y = mx + b. Your goal is to find m and b, since you already have x and y.
Pardon my bad handwriting. And sorry I don't know another faster way
Answer:
m = 2
Step-by-step explanation:
If we take two points from the graph, say (1, 2) and (2, 4)
we can use the formula (y2 - y1) / (x2 - x1).
y2 is the y of the second point, and y1 is the y of the first point, and same goes for x2 and x1.
If we use this formula, we get (4 - 2) / (2 - 1)
2 / 1
= 2
m = 2
