Step-by-step explanation:
Answer:
2( x +2 )
x+1
Step-by-step explanation:
to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]
since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators
combine x + x -2
factor [tex]x^{2}[/tex] - 4
to add or subtract expressions expand them and multiply by 1
have same denominator add them by adding their numerators
do the multiplications in 3 + ( x-2 )(x+2)
combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4
divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]
cancel out x-2 in both numerator and denominator
factor the expression that are not already factored
cancel out x-1 in both numerator and denominator
expand the expression

x + (4x-6) • 2
Step-by-step explanation:
First, let's start by calling the width of the rectangle x
Because the length is 4 times the width minus 6, the equation for length will be 4x-6
The width and length together will be x + (4x-6)
You then have to times it by 2 to find the whole perimiter.

Noticed how it forms a supplementary angle.
A supplmentary angle is basically two angles that added up to 180 degrees.
So we have:
64 + x = 180
Then we solve for "x", so "x" = 116.
Hope that makes sense :)
180-64=116

What is the value of q?
Answers
Answer:
q = 70°
Step-by-step explanation:
The 3 angles form a straight angle and sum to 180° , that is
q + 52° + 58° = 180°
q + 110° = 180° ( subtract 110° from both sides )
q = 70°
Answer:
q=70
Step-by-step explanation:
All the angles added up adds up to 180 so all you have to do is subtract the known angles from 180. Your equation should look like this
180-52-58=70

Write the equation of the line in slope-intercept form that goes through the points: (0, 5) and (4, 5)
Answers
Answer:
Step-by-step explanation:
The equation of a line written in slope-intercept form should be written as : y = mx + b
where m is the slope and b is the y-intercept.
We can find the slope, m, using the 2 points given:
(y2 - y1) / (x2 - x1) = (-12 -6) / (5- -4)
m= -18/9
m = -2
Then we can use this slope and one of the two points to find the intercept. Either point is fine but let's use (-4 , 6):
y = -2x + b
6 = -2 * -4 + b
6 = 8 + b
6-8 = 8 + b -8
-2 = b
The final equation of the line is: y = -2x -2

Step-by-step explanation:

a) Describe what is wrong with her method.
There two likely reasons why her answer is not correct;
- She did not arrange the numbers in order.
- The middle position belongs to two numbers, instead of finding the average she picked only one
b) Work out the median of the numbers in the list.
Arranging the numbers in ascending order;
29, 30, 31, 32, 33, 34, 34, 37
32 and 33 are both in the middle. The average of both numbers is the median
Median = (32 + 33) / 2 = 65 / 2 = 32.5

A membership to a movie night club costs $10 plus $2 per movie. Write the equation in slope intercept form to represent the situation
Answers
The equation in slope-intercept form is y = 2x + 10.
Option A is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Cost of membership = $10
Cost per movie = $2
The total cost for x movie.
= 10 + 2x
This can be written as,
y = 2x + 10
This is a slope-intercept form.
Where 2 is the slope.
Thus,
The equation is y = 2x + 10.

Step-by-step explanation:
Here we have a parallelogram, and we want to identify two segments that are parallel.
We can see that ON is parallel to LM
And LO is parallel to MN
Because this is a parallelogram (we know this because there is a 90° angle at N), the opposite sides are parallel.
So from this, we can see that sides ON and LM are opposite, then ON is parallel to LM
With the same reasoning, LO is parallel to MN.
