The answer is X>50. Hope this helps!
Since everything is half off, you save half of your money or %50.
Answer:
Step-by-step explanation:
slope=m= 5
points=(-1,2)
<u>By point-slope form:</u>
-
=m(
)
<u>Substitute the values in formula:</u>
<u>y-2=5(x+1)</u> (It is the point slope form)
Now,
<u>Slope intercept form:</u>
y-2=5x+5
y=5x+5+2
<u>y=5x+7</u>

Step-by-step explanation:
Answer:
At approximately x = 0.08 and x = 3.92.
Step-by-step explanation:
The height of the ball is modeled by the function:

Where f(x) is the height after x seconds.
We want to determine the time(s) when the ball is 10 feet in the air.
Therefore, we will set the function equal to 10 and solve for x:

Subtracting 10 from both sides:

For simplicity, divide both sides by -1:

We will use the quadratic formula. In this case a = 16, b = -64, and c = 5. Therefore:

Substitute:

Evaluate:

Simplify the square root:

Therefore:

Simplify:

Approximate:

Therefore, the ball will reach a height of 10 feet at approximately x = 0.08 and x = 3.92.
