Which of the following ordered pairs belongs to the graph of f(x)
Lera25 [3.4K]

Answer:

The second choice, (-1,\, 12).

Step-by-step explanation:

Note, that the expression y = f(x) is an equation. A point (x,\, y) is on the graph of y = f(x)\! if and only if the value of x and y satisfy this equation; that is: in other words, the y\!-coordinate of that point (the second number in the tuple) should be equal to f(x), which is equal to (-3\, x +9) (evaluated where x\! is equal to the first number in the tuple.

For each tuple in the choices, calculate the value of f(x) where x is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on y = f(x) only if these two numbers match.

  • First choice: x = 1, f(x) = f(1) = -3 + 9 = 6. That's not the same as the second number, -10. Therefore, this point isn't on the graph of y = f(x).
  • Second choice: x = -1, f(x) = f(-1) = (-3)\times (-1) + 9 = 3 + 9 = 12. That matches the second number in the tuple. Therefore, this point is on the graph of y = f(x).
  • Third choice: x = 2, f(x) = f(2) = (-3)\times 2 + 9 = 3. That's not the same as the second number, (-3). Therefore, this point isn't on the graph of y = f(x).
  • Fourth choice: x = -2, f(x) = f(-2) = (-3)\times (-2) + 9 = 15. That's not the same as the second number, 13. Therefore, this point isn't on the graph of y = f(x).

What is the answer to 7(2e−1)−3=6+6e
ludmilkaskok [199]
<span>Simplifying
7(2e + -1) + -3 = 6 + 6e

Reorder the terms:
7(-1 + 2e) + -3 = 6 + 6e
(-1 * 7 + 2e * 7) + -3 = 6 + 6e
(-7 + 14e) + -3 = 6 + 6e

Reorder the terms:
-7 + -3 + 14e = 6 + 6e

Combine like terms: -7 + -3 = -10
-10 + 14e = 6 + 6e

Solving
-10 + 14e = 6 + 6e

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-6e' to each side of the equation.
-10 + 14e + -6e = 6 + 6e + -6e

Combine like terms: 14e + -6e = 8e
-10 + 8e = 6 + 6e + -6e

Combine like terms: 6e + -6e = 0
-10 + 8e = 6 + 0
-10 + 8e = 6

Add '10' to each side of the equation.
-10 + 10 + 8e = 6 + 10

Combine like terms: -10 + 10 = 0
0 + 8e = 6 + 10
8e = 6 + 10

Combine like terms: 6 + 10 = 16
8e = 16

Divide each side by '8'.
e = 2

Simplifying
<span>e=2
