Answer:
approx. 44 km
Step-by-step explanation:
We are given that :
5 miles ------> 8 km
we divide both sides by 5 to get the unit rate:
1 miles ------> 8/5 km
Therefore:
27.5 miles -----> 27.5 miles x (8/5) = 44 km
Answer:
Step-by-step explanation:
d(x)=√((x-2)2+(y-0)²)
=√((x-2)²+y²)
=√((x-2)²+(x-1)²)
=√(x²-4x+4+x²-2x+1)
=√(2x²-6x+5)
D=d²(x)=2x²-6x+5
Answer:
I think the answer (-2, 6)
Answer:
x=3/8, y=-7/8. (3/8, -7/8).
Step-by-step explanation:
y=-5x+1
y=3x-2
----------
-5x+1=3x-2
-5x-3x+1=-2
-8x+1=-2
-8x=-2-1
-8x=-3
8x=3
x=3/8
y=3(3/8)-2=9/8-2=9/8-16/8=-7/8
Answer:
-2
Step-by-step explanation:
Therefore, the average rate of change over the interval [-4,-1] is -2.
