You will flip the signs when you have to multiply or divide your equation by a negative integer.
The answer to the question
Answer:
you simplify the fractions then you cross multiply
Step-by-step explanation:
1/2 * 4/2 you multiply 1 and 4 and you get 4/4 which is equal to 1
First, let's define our variables.
Let's call our width X(given)
and our length, since it's 10 shorter than 3 times the width, we can call our length:
3x-10
So, the perimeter of a rectange is equal to 2 times the length + 2 times the width.
So, when we plug our values in, we get

The perimeter is 8x-20
Answer:
slope =
Step-by-step explanation:
1) Calculate the slope using slope formula,
. Use the two points given, substitute their x and y values into the formula, and solve.

Thus, the slope is
.
