Answer: 1/3
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal.
For example, if slope of line A is a/b, then slope of line B which is perpendicular will be -b/a.
Substitute 1 and 3 for a and b. Apply the formula and get 1/3.
Answer:
Area of a rectangle = 42 square units
Step-by-step explanation:
Area of a rectangle = length times width.
l = (2c + 1) when c = 3, the length = 2 · 3 + 1 ; l = 6 + 1 = 7
w = (3 + c) when c = 3, the width = 3 + 3; w = 6
Area of a rectangle = length times width
Area of a rectangle = 7 · 6
Area of a rectangle = 42 square units
This is one way you could write out the steps
f(x) = -2x^2 - 5
f(2) = -2(2)^2 - 5
f(2) = -2(4) - 5
f(2) = -8 - 5
f(2) = -13
