An x intercept occurs whenever y=0.
y=(x-4)(x+2)
So for y=0, x=-2 or 4, so the x-intercepts are:
(-2, 0) and (4, 0)
Only (-2, 0) is within your answer choices.

Ammar hikes 2 3/4 miles of nature trail in 1 hour15 minutes. How many miles of trail does am mar hike per hour
AleksandrR [38]
Change 1 hour 15 minutes = 1.25 hour because 15 ÷ 60 = 0.25 so we add 0.25 hour and change 2 3/4 to 2.75
Equation:
Multiply 2.75 × 1 = 2.75 ÷ 1.25 =
2.2 miles
I'm pretty sure this is correct
