Answer:
Weight of an object=J
x=J/(379.2/150)
x=J/2.528
y=12.64/2.528
y=5
As given
The weight y of an object on Jupiter is proportional to the weight x of the object on Earth.
i.e
y = kx
where k is the constant of proportionality.
An object that weighs 150 pounds on Earth would weigh 379.2 pounds on Jupiter.
put in the eqaution
y = kx
379.2 = k × 150
k = 2.528
As given
A rock that weighs 12.64 pounds on Jupiter .
put in the equation
y = kx
12.64 = 2.528 × x
x = 5 pounds
Thus
A rock that weighs 12.64 pounds on Jupiter would weigh 5 pounds on Earth.
Therefore
y = A rock that weighs 12.64 pounds on Jupiter would weigh 5 pounds on Earth.

Answer:
Option B. The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
The correct quadratic equation is
This is a vertical parabola open downward (the leading coefficient is negative)
The vertex represent a maximum
Convert to vertex form
Factor -3
Complete the square
Rewrite as perfect squares
The vertex is the point (2,-21)
therefore
The equation has a maximum value with a y-coordinate of -21
Answer:
In 2001, beginning salaries would reach and exceed $50,000.
Step-by-step explanation:
50,000 = 2806.6 t + 32,558
50,000 - 32558 = 2806.6 t + 32,558 - 32558
17442 = 2806.6 t
17442/2806.6 = 2806.6 t /2806.6
6.2146 = t
1995 + 6.2146 = 2001.2146
in 2001
Answer: No
The ordered pair (2,4) is not a solution to the equation y = x-2
=========================================================
Explanation:
Any point is of the form (x,y)
So saying (2,4) means x = 2 and y = 4 pair together
Plug both of these values into the equation below
y = x-2
4 = 2-2
4 = 0
We get a false statement, so the original equation is false when (x,y) = (2,4)
---------------
Put another way, plugging x = 2 leads to...
y = x-2
y = 2-2
y = 0
But it should lead to y = 4 if (2,4) was a solution.
If your teacher said "(2,0) is a solution", then that would be a true statement.
