The answer is 9 ft because if you subtract 6 from 9 you get 3 then when you multiply 9*3 you get 27 ft. I hoped this helped you!!
The slope of your line is the x-coefficient: 5.
The slope of a perpendicular line is the negative reciprocal of that: -1/5.
(3x+2) (x-7)
FOIL
first 3x*x = 3x^2
outer 3x*-7 = -21x
inner = 2*x = 2x
last 2*-7 = -14
add them together = 3x^2 -21x+2x -14
combine like terms 3x^2 -19x -14
Answer:
8.75
Step-by-step explanation:
1 mile = 1.6 km
So, every 7 minutes, 1.6 km is ran.
Divide 1.6 by 2 to figure out how much more she is running.
1.6 / 2 = 0.8
Divide the known pace by the extra distance to figure out the time
7 min / 0.8 km = 8.75 min
