Answer:
50 – (3x + 4y + 25)
Step-by-step explanation:
To see how much change she is gonna receive we need to find how much she spent on the items and add them all up:
The calculator was $25
The price of pens and notebooks are unknown so they are represented with x and y respectively.
With given information we can write the following equation to see the change she will receive:
50 – (3x + 4y + 25)
What am I looking for exactly? lol
Answer:
The coefficient of squared term is 1/9
Step-by-step explanation:
The vertex of parabola is (2.-3)
We know the vertex form of a standard parabola

Plugging values of h and k, h= 2, k = -3

Now, x=5, y=-2




Thus, the coefficient of squared term is 1/9
The equations of both the sister are the same.
<h2>Expression
</h2>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
<h2>Given to us</h2>
Gabriel Equation:
,
Gabriel's Sister Equation:
,
<h3>Gabriel's Sister Equation</h3>
On further solving the equation we get,

As we can see the equation transformed to Gabriel's Equation of total cost.
Therefore, both the sisters are correct as the equations of both the sister are the same.
