$\text{First, simplify the equation:}\\\\5x+5y=25\\\\\text{Subtract 5x from both sides}\\\\5y=-5x+25\\\\\text{Divide both sides by 5}\\\\y=-x+5\\\\\text{The slope of the line is -1, so this is a linear equation, due to the fact}\\\text{that the slope is at a constant "rate of change"}\\\\\boxed{\text{Yes, it's a linear equation}}$

hich function has a range of {y|y ≤ 5}? f(x) = (x – 4)2 + 5 f(x) = –(x – 4)2 + 5 f(x) = (x – 5)2 + 4 f(x) = –(x – 5)2 + 4

Brums [2.3K]

Answer:

$f(x)=-(x-4)^2+5$

Step-by-step explanation:

The function $f(x)=-(x-4)^2+5$ has the vertex at $(4,5)$ .

Since $a=-1\:$ , the graph of the function is a maximum graph.

The highest y-value is the y-coordinate of the vertex which is 5.

Therefore the range is { $y|y\le 5$ }

Therefore the correct answer is B.
