Answer:
Step-by-step explanation:
1.
Equation one:
x = -5, x = -1 (Both are real)
Equation two:
No real solutions
Equation three:
x = -3 (Real)
Equation four:
No real solutions
2.
The easiest way to figure out if an equation has real solutions is to factor it. If it is factorable, then it has real solutions. If it isn't, then it doesn't have real solutions.
3 because 2*12 24 24/8 is 3 hope this helps

I got this by putting the numbers in their place
<span>If the tip, t, varies directly with the number of guests, g, then
it means that any change in tip there is a corresponding change in the
number of guests. When the tip increases the number of guests increases
as well. Therefore,
t </span>α g
To change the it to equal sign, we incorporate a proportionality constant, k.
t =<span> kg
</span>
This equation will represent the relation of t to g
