<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs

distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:

Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles

Hope this helped :)</span>

Find The Zero Of The Function <br> F (x)=x^2+3x-10 <br> And <br> F (x)=-x^2+8x+9
Olegator [25]
1)
F(x)=x^2+3x-10 \\&#10;0=x^2+3x-10 \\&#10;0=x^2-2x+5x-10 \\&#10;0=x(x-2)+5(x-2) \\&#10;0=(x+5)(x-2) \\&#10;x+5=0 \ \lor \ x-2=0 \\&#10;x=-5 \ \lor \ x=2 \\ \\&#10;\hbox{the function has two zeroes: x=-5 and x=2}

2)
F(x)=-x^2+8x+9 \\&#10;0=-x^2+8x+9 \\&#10;0=-x^2-x+9x+9 \\&#10;0=-x(x+1)+9(x+1) \\&#10;0=(-x+9)(x+1) \\&#10;-x+9=0 \ \lor \ x+1=0 \\&#10;x=9 \ \lor \ x=-1 \\ \\&#10;\hbox{the function has two zeroes: x=-1 and x=9}

IF THE ORIGINAL POINT IS (6,15) AND THE SCALE FACTOR IS 1/3,WHAT IS THE NEW POINT
AysviL [449]
I believe it would be (9, 16). My reasoning for this is that if the slope is 1/3, then x would increase by 3 and y would increase by 1.
