Answer: You spent 5 hours babysitting.
Step-by-step explanation:
This situation can be represented by the equation y = 8x+ 10 where y is the money you earn and x is the number of hours.
So if y is equation to fifty dollars then what is x ?
50 = 8x +10 subtract 10 from both sides.
-10 -10
40 = 8x
x = 5

Answer: a) k >4.08
b) k = 4.08
c) k<4.08
Step-by-step explanation:
Since we have given that

a) For what values of k will the function have no zeros?
It mean it has no real zeroes i.e. Discriminant < 0
As we know that

Here, a =-3
b = 7
c = -k
So, it becomes,

b) For what values of k will the function have one zero?
It means it has one real root i.e equal roots.
So, in this case, D = 0
So, it becomes,

c) For what values of k will the function have two zeros?
It means it has two real roots.
In this case, D>0
So, it becomes,

Hence, a) k >4.08
b) k = 4.08
c) k<4.08
