Answer:
c
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and
b is the y-intercept.
y=mx+b
m=−3
b=0
y=-3x+0

Answer:
Step-by-step explanation:
Let
y ----> the length of the board
x ----> the width of the board
we know that
----> equation A
The area of the board is
----> equation B
substitute equation A in equation B
About 20 it depends on how big the termite is.
<h2>
Hello!</h2>
The answer is: D) 6.2 seconds
<h2>
Why?</h2>
When the egg hit the ground, the height will be equal to 0, so, from the given equation we need to find the roots or zeroes.
It's a quadratic function, we can find the roots using the quadratic equation:
So, from the given function we know that:
So, substituting we have:
So, since the time can not be a negative value, the correct option is:
6.18≈6.2 seconds
Hence, it takes 6.2 seconds to the egg to hit the ground.
Have a nice day!
