Step-by-step explanation:
The complete question in the attached figure
Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?
Let
x -----> the amount of money contributed by Anna
y ----> the amount of money contributed by her mother
we know that
Looking at the table
The value of x is equal to
The value of y is equal to
Find the ratio x/y
substitute the values
Part 2) What was the total amount saved in April?
we know that
To find out the total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April
so
The graph can be drawn by the placing the points and after translation points becomes A'(-3, -5), B'(-2, 3), C'(1, 4), and D'(0, -5)
<h3>What is quadrilateral?</h3>It is defined as the four-sided polygon in geometry having four edges and four corners.
We have:
Quadrilateral ABCD with vertices A(2,-3), B(3,5), C(6,6) and D(5,-3)
We can graph it on the coordinate plane as shown in the picture.
After applying the translation (x, y)→(x−5, y−2), the points becomes:
A'(-3, -5)
B'(-2, 3)
C'(1, 4)
D'(0, -5)
Similarly, we can graph it on the coordinate plane (refer attached picture)
Thus, the graph can be drawn by the placing the points and after translation points becomes A'(-3, -5), B'(-2, 3), C'(1, 4), and D'(0, -5)
