Answer:
$3 per kg of rice
Step-by-step explanation:
To find the unit price of the rice, you have to divide the price of 2.5 kgs by 2.5 to get to the base unit of 1 kg.
7.50/2.5=3
So, it is $3 for every kg of rice.
B is the correct. Because if you look at the problem I can turn it around and see
First we pick the equation. Let's say we pick first one. From it we express y.
Then we use this y and plug it in instead of y in the second equation.
Now just solve for x.
We plug this x in the first equation.
And solve for y.
So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.
Hope this helps.

Answer:
A rocket is launched from a tower. The height of the rocket, y in feet, is
Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+129x+119
y=−16x
2
+129x+119
Answer:
As far down/low as you can go.
Step-by-step explanation:
Usually used with upper and lower bounds it means that the "greatest decrease" you can go is 4.5 for example.
If that is what you meant then hope this helps :)
