Step-by-step explanation:
what is the problem here you don't understand ?
you understand the words "equality" and "inequality" ?
this is all about the question, if something is equal to something else or not - meaning of they are the same or at least the same size.
an expression without an equal ("=") or unequal sign ("<", ">", ">=", "<=", "<>" - if you don't understand these symbols, please ask, they are simply basic keyboard symbols for the scientific symbols) is not any form of that - no equality, and no inequality.
so,
1. is NOT
2. is NOT because it has an equality symbol
3. is a quadratic inequality (when doing the multiplication of both bracket terms, there will be an x×x=x² part) - it has a ">" (greater) symbol
4. is a quadratic inequality (there is a x² term as highest power of x included) - it has a "<=" (smaller or equal) symbol
5. is a quadratic inequality (there is a x² term as highest power of x included) - it has a ">" (greater) symbol

Answer:
x = -102
Step-by-step explanation:
Step 1: Multiply both sides by 10.
[tex]\frac{8-x}{10} * 10 = 11*10[/tex] [tex]8-x = 110[/tex] [tex]-x + 8 = 110[/tex]Step 2: Subtract 8 from both sides.
[tex]-x + 8 - 8 = 110 - 8[/tex] [tex]-x = 102[/tex]Step 3: Divide both sides by -1.
[tex]\frac{-x}{-1} = \frac{102}{-1}[/tex] [tex]x=-102[/tex]Step 4: Check if solution is correct.
[tex]\frac{8-(-102)}{10} = 11[/tex] [tex]\frac{8+102}{10}=11[/tex] [tex]\frac{110}{10}=11[/tex] [tex]11 = 11[/tex]Therefore, x = 11.

Answers
Answer:
56
Step-by-step explanation:
The required simplified value of the given expression is 4.
Given that,
An expression is given, {[(12−36)÷(−12)]2−20}÷(−4 a simplified value of the expression is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Simplifying,
= {[(12−36)÷(−12)]2−20}÷(−4)
=[ [-24/-12]2-20] / - 4
=[4-20] / - 4
= -16/-4

A tire shop had to fill 2 1/2 tires with air. It took a small air pump 2 1/2 seconds to fill them up. How long will it take to fill 8 tires?
Answers
Answer:
8 seconds if tyres took 1 second each tyre as 2.5/2.5 =1
The question did specify 2 1/2 secs to fll them all up which is 1 second each x 8 = 8 sec total.
Step-by-step explanation:
2 1/2 litres = number of tyres
2 1/2 seconds taken
= if each tyre took 2 1/2 seconds the quetsion should say clear but would be
2 1/2 tyres x 2 1/2 seconds = 6.26 seconds every 2 1/2 tyres
so 8 tyres x 2 1/2 seconds = 20 seconds every 8 tyres
If the 2 1/2 seconds applied to all 2 1/2
then we need to find a multiplier for 1 tyre
Here we divide
2 1/2 / 2 1/2 = 1
8 x 1 = 8 seconds.

If y = xy + x2 + 1, then when x=-1,
dy/dx
Answers
dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.
If y = xy + x² + 1, then when x=-1,
dy/dx = -1/2
What is Derivatives?The rate of change of a function with respect to a variable are called Derivatives.
Given that, y = xy + x² + 1
Put x = -1 we get,
y = -1y + (-1)² + 1
y = -y + 1 + 1
y = 1
Now Differentiating the given equation w.r.t x
dy/dx = xdy/dx + y + 2x
dy/dx - xdy/dx = y + 2x
dy/dx (1 - x) = y + 2x
dy/dx = (y + 2x)/(1 - x)
Put x = -1 and y = 1 we get
dy/dx = (1 + 2(-1))/(1 - (-1))
dy/dx = -1/2
Hence, y = xy + x² + 1, then when x=-1,
dy/dx = -1/2

pick-m-up towing company charges 40$ to hook a car and 1.70 for each mile that it is towed. write an equation that represents the total cost y for x miles towed. find the y intercept, and interpret its meaning in the context of the situation
Answers
Using linear function concepts, it is found that:
The equation for the cost of x miles towed is: [tex]y = 1.7x + 40[/tex].The y-intercept is [tex]y = 40[/tex], which means that the flat fee is $40.A linear equation for a cost has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the fixed cost, also called flat fee.In this problem:
The y-intercept is the cost to hook a car, which is $40, thus [tex]b = 40[/tex] and the flat flee is $40.Cost of $1.70 per mile towed, thus the slope is [tex]m = 1.7[/tex].Then, the equation for the cost is given by:
[tex]y = 1.7x + 40[/tex]
