Answer:
Janet makes 9 dollars per hour which is more that Giovanna makes.
Step-by-step explanation:
Its very simple
All you have to do is divide like Giovanna make 42 dollars every 6 hours
42/6=7
Also for Janet she makes 54 dollars every 6 hours
54/6=9
Given a quadratic equation in standard form

The discriminant D

tells the types of roots the equation has.
In this case, we have

Then, the discriminant of this quadratic equation will be

Finally, the value of discriminat is 49 and as he discriminant is greater than zero then this quadratic equation has 2 different real solutions.

With graphs on paper you can visually see intersecting lines(one solution), identical lines
(infinite solutions), or parallel lines(no solutions).
This method works best for lines that have integers for solutions. The task of determining rational or irrational solutions from graphs is difficult.
The substitution method usually must be used for equations with higher exponents. The deawback of this method is having to work with fractions.
The elimination method is often the method of choice.
This method however requires that you learn to recognize when the systems produce parallel lines or have equations that represent the same lines.
Answer:
(x, y) → (x + 6, y + 13)
Step-by-step explanation:
<u>Let's use one of the points to determine the transition:</u>
- Coordinates of D = (-5, -7)
- Coordinates of D' = (1, 6)
<u>Transition:</u>
- x' - x = 1 - (-5) = 6
- y' - y = 6 - (-7) = 13
<u>So the rule is:</u>
