Tell whether the lines with the given slopes are parallel, perpendicular, or neither. Line 1: m = 2 2)

Mathematics

Answer and Step-by-step explanation: Two lines can be parallel, perpendicular or none of them. The difference is in the slope of a line.

<u>Slope</u> is the change in y over the change in x, or, in other words, it is the steepness of the line.

Two lines are parallel if they don't intersect. So, they have the same slope and different y-intercept. For example:

f(x) = m₁x + b₁

g(x) = m₂x + b₂

Functions f(x) and g(x) are parallel if

m₁ = m₂ and b₁ ≠ b₂

Two lines are perpendicular when they intersect at a 90° angle. For that to happen, the multiplication of the slope of each function must result in -1. For example:

h(x) = m₃x + b₃

j(x) = m₄x + b₄

The functions will be perpendicular if:

m_{3}m_{4}=-1

If the slopes are not the same or reciprocal, the lines are neither.

What is the linear function equation that best fits the data set?
slavikrds [6]

Answer:

Option 3

Step-by-step explanation:

Given data set is,

{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}

By using linear regression calculator,

Equation of the linear function will be,

y = 2x - 2

Therefore, Option 3 will be the correct option.

in a class of 20 students, 40% are boys. 25% of the boys and 50% of the girls wear glasses. How man students wear glasses?
statuscvo [17]
20 students.

40% are boys. (40/100)*20 = 0.4 * 20 = 8 boys.
Girls= 20 - 8 =  12 girls.

25% of the boys wear glasses. = (25/100)*8 = 0.25*8 = 2 boys wear glasses.
50% of the girls wear glasses. = (50/100)*12 = 0.50*12 = 6 girls wear glasses.
   
Total students that wear glasses = 2 + 6 = 8 students.
8 students wear glasses.

Given f(x) = 7x^9, find f^-1 (x). Then state whether f^-1 (x) is a function
Olin [163]
A though without graphing software it would appear to be C


Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.
