Answer:

(x-5)*(x+5)

Step-by-step explanation:

= x^2 + 5x - 25 - 5x

= x^2 +5x - 5x -25

because +5x - 5x = 0 so

= x^2 + 0 - 25

= x^2 - 25

25 can be written as 5^2

= x^2 - 5^2

we know that a^2 - b^2 = (a-b) * (a+b)

so x^2 - 5^2

= (x-5) * (x+5)

Hope this help you :3

What is the inequality?

vlabodo [156]

Answer:

y < 0.25x + 4

Step-by-step explanation:

The dotted line indicates that the inequality is either a greater than(>) or less than(<). This is because the answer does include the set of points along the line.

We are looking to find an inequality such that any point below that is considered a solution. Thus, after finding the line's equation in slope-intercept form, we can replace the = with <.

Solving for the line:

Take any 2 points and determine the slope. I used (-8,2) and (0,4). The slope using $\frac{y_2-y_1}{x_2-x_1}$ results in $\frac{1}{4}$ or 0.25. As we can see visually from the graph, the y-intercept is (0,4). Thus, the equation of the line is y = 0.25x + 4.
