Answer:

Either of ...

(x, y) ⇒ (-x, -y)
Rotation 180° about the origin

Step-by-step explanation:

There are at least two ways to express the transformation that maps each coordinate to its opposite.

1. reflection across the origin: (x, y) ⇒ (-x,-y)

2. rotation 180° (either direction) about the origin.

Take your pick.

Jane is given a $100 gift to start and saves $35 a month from her allowance.

After 1 month, Jane has saved

After 2 months, Jane has saved

After three months, Jane has saved

and so on

In general, after x months Jane has saved

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.

What is the difference in length between a 11/4 inch button and a 3/8 inch button

Nutka1998 [239]

Answer:

$\frac{19}{8}$

Step-by-step explanation:

First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.

Then, cross-multiply. 11 × 8 = 88, so $\frac{11}{4}$ becomes $\frac{88}{32}$ . 3 × 4 = 12, so $\frac{3}{8}$ becomes $\frac{12}{32}$ .
