Answer:
Solving Inequalities is very similar to solving Equations.
If you multiply or divide one side of an equation or inequality by the same number, you have to multiply or divide the other side of the equation or inequality by the same number.
The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses.
The comparison between inequalities and equation written down below.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other.
To solve the inequality,
you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
To solve an equation,
Remove parentheses and combine like terms to simplify each side of the equation. To isolate the variable term on one side of the equation, use addition or subtraction. To find the variable, use multiplication or division.
Hence, the process of solving equations and inequalities.

-x - 14 > 6x + 8 + 4x
Answer:
x<-2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−x−14>10x+8
Step 2: Subtract 10x from both sides.
−x−14−10x>10x+8−10x
−11x−14>8
Step 3: Add 14 to both sides.
−11x−14+14>8+14
−11x>22
Step 4: Divide both sides by -11.

The future value of an investment is 10,110.28 if money was originally invested at 3.5% compounded semi annually for 5 years what was the amount of the original investment
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Compound Interest.
Since we know that formula for the Compound interest is :-
A= P(1+r/n) ^nt
here, A = total amount received at end, P= initial amount invested, r= rate of interest in decimal, t= time of years and n= frequency per year, so we get as,
=>10110.28 = P(1+0.035/2)^2*5
=>10110.28 = P (1+0.0175)^10
=>10110.28= P(1.0175)^10
=>so finally we get as
=>P= 1011.28/1.1894
=> P= 8500
Using Concept of the Compound Interest, the amount of the original investment was $8500.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =A= P(1+r/n) ^nt
Where, A = total amount received at end, P= initial amount invested, r= rate of interest in decimal, t= time of years and n= frequency per year,
Therefore, we get as,
10110.28 = P(1+0.035/2)^2 x 5
10110.28 = P (1+0.0175)^10
10110.28= P(1.0175)^10
so finally we get as;
P= 1011.28/1.1894
P= 8500
Using Concept of the Compound Interest, the amount of the original investment was $8500.

Points $A$ and $B$ have the same $y$-coordinate of 13, but different $x$-coordinates. What is the sum of the slope and the $y$-intercept of the line containing both points?
Answer:
13
Step-by-step explanation:
This one sounds really hard, but its actually really easy once you think about it.
The problem states that both y coordinate are 13, but have different x coordinates. It asks for the sum of the slope and the y intercept. The y intercept will always have 0 as x.
To find a slope, the equation is y2-y1/x2-x1. In this case, we don't actually know what x is. But we do know what y is:
13-13/x2-x1
0/x2-x1
0
So the slope is 0.
Since we know that the y intercept has to have 0 as x, we don't actually need to know what x is.
So the y intercept is 13.
13+0=13.

Step-by-step explanation:
An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle
Sum of two angles that are supplementary = 180°
Let the first angle be x .
Then the other angle = x + 40
Measure of each angle =
[tex]x + x + 40 = 180[/tex]
[tex]2x + 40 = 180[/tex]
[tex]2x = 180 - 40[/tex]
[tex]2x = 140°[/tex]
[tex]x = \frac{140}{2} [/tex]
[tex]x = 70°[/tex]
Which means :-
The first angle:-
[tex]= x = 70°[/tex]
The second angle :-
[tex]x + 40[/tex]
[tex]70 + 40[/tex]
[tex] = 110°[/tex]
Therefore , the two supplementary angles are 70° and 110° .

Answer:
fourty five
Step-by-step explanation:
I will give brainiest How does the function y = -2x + 6 differ from the linear parent function?
So the parent function is y=x, right? y=-2x+6 is different because the slope is -2 (which flips the line so it's now going from left to right while also being more "taller", and the line's y-intercept is 6, while on the parent function, the y-intercept is 0.
Parent function: y = x (or y=mx+b)
Your function: y = -2x+6
6 = y-intercept (b)
-2 = slope (m)

Once upon a time a farmer went to a market and purchased a wolf, a goat, and a
cabbage. On his way home, the farmer came to the bank of a river and rented a
boat. But crossing the river by boat, the farmer could carry only himself and a
single one of his purchases: the wolf, the goat, or the cabbage.If left unattended
together, the wolf would eat the goat, or the goat would eat the cabbage.The
farmer's challenge was to carry himself and his purchases to the far bank of the
river, leaving each purchase intact. How did he do it?
Given that the wolf would eat the goat, the goat would eat the cabbage but the wolf wouldn't eat the cabbage.
So, leave the wolf and cabbage behind (at side 1) and take the goat to the other side (side 2) of the river.
Then, come back with the empty boat from side 2 to side 1.
Take the wolf (or the cabbage) from side 1 to side 2 of the river.
Now, observe that, the goat is already on side 2, and the wolf and the goat can't be on the same side as the wolf would eat the goat, So, leave the wolf on side 2 and come back with the goat from side 2 to side 1.
Leave the goat on side 1 and take the cabbage from side 1 to side 2.
Now, come back with the empty boat from side 2 to side 1 and take the goat from side 1 to side 2.
In this way, the farmer can carry himself and his purchase to the other side of the river.
