What two numbers multiply to 10 and add to -29 ?

Degger [83]

Xy=10
x+y=29

subtract x from both sides for second equation

y=-x-29
subsitute in second equaiton
x(-x-29)=10
-x^2-29x=10
add x^2+29x to both sides
x^2+29x+10=0
quadratic formula
if you have
ax^2+bx+c=0,
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

so
x^2+29x+10=0
a=1
b=29
c=10
x= $\frac{-29+/- \sqrt{(-29)^{2}-4(1)(10)} }{2(1)}$
x= $\frac{-29+/- \sqrt{841-40} }{2}$
x= $\frac{-29+/- \sqrt{801} }{2}$
x= $\frac{-29+/- 3\sqrt{89} }{2}$

x= $\frac{-29- 3\sqrt{89} }{2}$ or $\frac{-29+ 3\sqrt{89} }{2}$
those are the 2 numbers
aprox=-28.65 and -0.349

for every 4 miles Vanessa jogged, Cody jogged 3 miles. if Vanessa jogged 1 mile, how far would Cody have jogged

Ksju [112]

Alright here's the breakdown:

it said every 4 miles Vanessa jogged, Cody jogged 3 miles.

so

Vanessa jogged 1 mile

that means

Cody jogged .75 of a mile ( or 75% of 1 )

because

Cody will always jog 75% of how much Vanessa joged

so say that

Vanessa jogged 50 miles

all you do is take 75% of how much Vanessa jogged

and that should be how much Cody joged

hopes this helps!
