F(x) = - x - 5
f(4) = -4 - 5 = -9
Answer: f(4) = -9
At first, she had +2y in the upper and -5y in the lower.
She multiplied the upper by 5 . Then she had +10y in the upper.
She should multiply the lower by 2 . Then she'll have -10y
there. She'll be able to add the two equations, and the 'y's will
go away. She'll be left with a single equation with only 'x' in it,
and she can solve that one for the value of 'x'.
Answer:
D) -3
Step-by-step explanation:
Slope of a linear function:
The slope of a linear function is the amount by which y changes when x increases by 1.
In this question:
When x = 1, y = 12
When x = 2, y = 9
When x = 3, y = 6
When x = 4, y = 3
So each time x increases by 1, y decreases by 3, which means that the slope is -3, and the answer is given by option D.
