Answer:

y = (-5/4)x + 5

Step-by-step explanation:

Slope-intercept form is y = mx + b

m is the slope and b is the y-intercept

To find m, we can use the plotted points on the graph

(0,5)(4,0)

Now, do delta y/ delta x

(0-5)/(4-0)

slope = -5/4

Now, the y-intercept is the point where the graph crosses the y-axis

This point is where x is 0. Here, when x is 0, y is 5.

Therefore, the y-intercept is 5

Finally, replace what you've found into the equation

y = (-5/4)x + 5

y = -3x - 2

Since a < 0 we have a decreasing line, so it can be only the first or the last

And if we solve the equation for y = 0 we have

0 = -3x - 2

3x = -2

x = -2/3

So, the last one is the right

g100num [7]

Answer:

16.58 feet

Step-by-step explanation:

a² + b² = c²

Think of this as a right triangle

The hypotenuse is 30, and one of the legs is 25

To find the other leg, subtract the square of the hypotenuse by the square of the given leg

30² - 25² = leg

900 - 625 = 275

Square root the answer to find the length of the missing leg

√275 = 16.583123951777

The leg is 16.58 ft.
