Answer: the no.s are-
2.472
-6.472
Step-by-step explanation:
xy=24-----1
x+y=-4------2
from 2 we get x=-4-y
sustituting=
into 1 we get
quadratic eq = y^2 + 4y + 24=0
so
-4+- root 16-96/2
thus on further solving we get -2 +-4.472
on adding= -2+4.472= 2.472
on subtraction= -2 -4.472= -6.472
Answer:
y int (0, -45) x int (-10, 0)
The total distance is 15 miles.
Biking 75 miles in 300 minutes gives us the ratio 75/300 = 1/4, or 1 mile per 4 minutes.
Running 30 miles in 240 minutes gives us the ratio 30/240 = 1/8, or 1 mile per 8 minutes.
If she bikes 48 minutes, 48(1/4) = 48/4 = 12 miles.
If she runs 24 minutes, 24(1/8) = 24/8 = 3 miles.
This is a total distance of 12+3= 15 miles.
The correct answer is 7.2
We can subtract 2 from 4, which is 2.
They're both in the same decimal place, so that is why they are affecting each-other.
