Question

Is (2, -9) a solution to the function 7d - 5 = t(d)? Explain how you came to your answer.

A) Yes, because it satisfies the equation.
B) No, because it does not satisfy the equation.
C) Yes, because it makes the left side equal to the right side.
D) No, because it doesn't affect the equation

Answer 1

The correct answer is B.

t(2) = 7(2) - 5 = 14 - 5 = 9

So (2, -9) is not a solution to this function.

Answer 2

No, because it does not satisfy the equation.

Step-by-step explanation:

The question is asking whether the point (2, -9) is a solution to the given function 7d - 5 = t(d). To determine if it is a solution, we need to substitute the values of d and t in the equation and see if both sides are equal.

When we substitute d = 2 and t = -9 into the equation, we get:

7(2) - 5 = -9(2)

14 - 5 = -18

9 = -18

The equation is not true, so (2, -9) is not a solution to the function 7d - 5 = t(d). Therefore, the correct answer is B) No, because it does not satisfy the equation.
