Jada is looking to earn some extra money over summer break so she starts a babysitting service with some of her friends. The babysitting service charges a flat fee of $10 to book a
babysitter and then charges a different amount per hour based on which person is
babysitting. Jada eams d dollars per hour and works for h hours one night. Her total
earnings, T. can be represented by the equation:
T= dh + 10
Write the equation that can be used to easily find the amount of hours, h, Jada worked if
we know her hourly rate, d, and her total earings, T.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
