Answer:

Step-by-step explanation:

to find 4, you use the equation $a^{2}+b^{2}=c^{2}$ where the c= hypotenuse, which is the slant of the triangle. Then you width and length can by put as a and b. This gives you $15^{2}+4^{2} = s^{2}$ . Then you solve for s which end up being 15.5.

We can solve it, but we can't actually use the interactive system they want you to use. Let's see if we can guide you through it.

My guess is you can control the lines by dragging the two points on the line.

Let's make the green line y = 2x + 3

When x=0 we get y=3, point (0,3). That's the y intercept, 3 up on the y axis. Drag one green point there.

When x=2 we get y=7, point (2,7), two to the right, seven up. Drag the other green point there. The green line is now y = 2x + 3.

Similarly the red line is made y = -3x + 3. When x=0, y=3, point (0,3). [Surprise!] When x=2, y=-3, point (2,-3). Drag the red points to (0,3) and (2,-3).

We already saw where they meet, at (0,3), x=0, y=3, the y intercept of both lines.

Answer: x=0, y=3

In two or more complete sentences, describe how to find the interval(s) where the function is increasing and how interval notati

Novay_Z [31]

Answer:

(-5,0)

Step-by-step explanation:

In case when you tracking the finger across the line, at which there is an increase or decrease in y axis so this is we called intervals. Moreover, the interval notation is also necessary as it depicts the beginning and ending points. In this, the first number denotes the minimum number while the second number denotes the maximum number

For Decreasing:

(-8,-5)

(4,8)

For Increasing:

(-5,0)
