Answer:
X' is (5,-5)
Step-by-step explanation:
Knowing that this is just a translation, we can reverse the (polarity?) of each equation, such as changing -5 to +5 to find the original answer.
With that in mind, we can add 2 to X, and -1 from Y, which puts us at, 5 on the X axis, and -5 on the Y axis.
The formula of a slope:

We have the points A(-7, a) and B(c, d).
Substitute:

Exception: c ≠ -7.
The situation that is a function is: C. The weight of a package and the cost of postage.
<h3>What is a Function?</h3>
A function can be described as a relation whereby there can only be one exact possible output value (dependent variable) for every input value (independent variable) in the relation. This means, no input value has two different output values. However, two different input values can have the same output value.
In a function, the output value is dependent on the input value.
For example, the cost of postage (output) is dependent on the weight of a package (input).
Therefore, the situation that is a function is: C. The weight of a package and the cost of postage.

Answer:
$52
Step-by-step explanation:
35% off
100% - 35% = 65%
