Write x/2 - 2x + 4/ x + 1 as a single fraction, in its simplest form.
Answer:
x²-3x - 8 2(x + 1)
Explanation
Find common denominator and write the nu merators above common denominator:
x(x + 1) − (2x + 4) × 2
2(x + 1)
Apply Multiplicative Distribution Law :
x² + x - 4x = 8

Answer:
Option A. The student incorrectly used < instead of > for the second inequality. The correct inequality is >.
Step-by-step explanation:
Defintions:Boundary lines that are often used in systems of linear inequalities determine the location of the solutions region in a coordinate plane.
Solid boundary lines are used for the equal sign, "=," and the inequality symbols "≥" and "≤." This implies that the points along the line (endpoints) are included as solutions to the given system. Dashed boundary lines are used for inequality symbols, ">" and "<." Using the dashed lines as the boundary implies that the points along the line (endpoints) are not included as solutions to the given system. Solution:Given the systems of linear inequalities: y ≤ 0.5x + 1 and y = -2x + 1:
In order to determine what is the appropriate inequality symbols for both equations, we must first set the second equation with an equal sign. Then, choose a test point (not in either lines) to determine which half-plane region must be shaded.
Test point: (0, 0)
Substitute the test point into both equations to determine whether it satisfies the given equation:
y ≤ 0.5x + 10 ≤ 0.5(0) + 1
0 ≤ 0 + 1
0 ≤ 1 (True statement).
y = -2x + 20 = -2(0) + 2
0 = 0 + 2
0 = 2 (False statement). Therefore, the half-plane region that doesn't contain the test point must be shaded. Hence, we must use the ">" symbol for this equation, as we're shading "above" where the values for y is greater than the y-intercept, (0, 2).
Therefore, the correct answer is Option A: The student incorrectly used < instead of > for the second inequality. The correct inequality is > (greater than symbol).

A small package of 12 pencils costs $2.04. A large package of 60 pencils costs $9.60. Which is a
better deal? How do you know?
You can use a calculator but you must show your work and explain your thinking.
Answer:
60 pencil
Step-by-step explanation:
60 divided by 12 is 5
5 times $2.04= 10.2
so if you buy the 12 pack you would be spending more money!

A line passes through the points (4, 6) and (8, 7). What is its equation in point-slope form?
Hello there! :)
First, let’s find the slope.
We can find it using this formula:
m=y2-y1/x2-x1
m=7-6/8-4
m=1/4
So the slope is 1/4.
Now, we can use the point-slope formula:
y-y1=m(x-x1)
y-6=1/4(x-1/4)
Hope it helps. :)

Answer:
x < 4
Step-by-step explanation:
3x - 3 < 9 ( add 3 to both sides )
3x < 12 ( divide both sides by 3 )
x < 4
Answer:
x < 4.
Step-by-step explanation:
3x - 3 < 9
Add 3 to both sides:
3x < 9 + 3
3x < 12
Divide both sides by 3:
x < 4.

Find the unit rate for each problem.
Answer:
1. 11 players per team
2. 60 miles per hour
3. 25 games per season
4. 60 words per minute
Step-by-step explanation:
1) 132 players divided by 12 teams = # of players per team
132/12 = 11 players per team
2) 240 miles divided by 4 hours = # of miles per hour
240/4 = 60 miles per hour
3) 125 games divided by 5 seasons = # of games per season
125/5 = 25 games per season
4) 180 words divided by 3 minutes = # of words per minute
180/3 = 60 words per minute

[1] Complementary means the angles will add up to 90 degrees
() Blank one is BOC
() Blank two is 90
() Reason blank I am unsure as I do not know the wording that is being looked for, but it is either "given," "complementary angles" or something similar
[2] Since AOC is equal too BOC + 30, we can decide the following is true
() First blank is BOC
() Second blank is 30
[3] 30°
() BOC + BOC + 30 = 90 [Given]
2(BOC) = 60 [Subtract 30 from both sides & combine like terms]
BOC = 30 [Divide by 2]
[4] 60°
() 90 - 30 = 60

Given that lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and measure of angle 7 Explain your reasoning and show your work.
tysm in advance
The required measure of the angle 1 and 7 is given as 130° and 40° respectively.
Given that,
Lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and the measure of angle 7 .
The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
here,
From the figure,
∠1 = ∠5
4x - 30 = 2x + 50
2x = 80
x = 40
Now,
∠ 1 = 4 [40] - 30
∠1 = 130° = ∠5
∠7 = 180 - ∠5
∠7 = 180 - 130 = 40°
Thus, the required measure of the angle 1 and 7 is given as 130° and 40° respectively.
