The compound inequality solving original inequality |3x – 5| > 10 is given by: Option C: [tex]3x - 5 < -10[/tex] or [tex]3x -5 > 10[/tex]
What is magnitude and sign?A number has both magnitude(its absolute value) and its sign(positive or negative).
If numbers are negative, the more their magnitude increases, the lesser they become.
If numbers are positive, the more their magnitude increases, the greater they become.
Thus, for -5, the magnitude is 5, and sign is –ve.
Also, positive numbers > 0 > negative numbers.
|x| = magnitude of x.
Thus, |3x-5| > 10 is true if (3x-5) < -10 (since in that case, 3x-5 is negative but in negative signed values, values with more magnitude are smaller. Thus |3x-5| > |-10} = 10)
or (3x-5) > 10
(in case if (3x-5) is non-negative).
Thus, the compound inequality solving original inequality |3x – 5| > 10 is given by: Option C: [tex]3x - 5 < -10[/tex] or [tex]3x -5 > 10[/tex]

Two trains, Train A and Train B, weigh a total of 473 tons. Train A is heavier than Train B. The difference of their weights is 397 tons. What is the weight of each train?
Answer:
You say
473- 397
=76
So maybe train A is 76 tons while train B is 397

What is the domain of the function y = StartRoot x 6 EndRoot minus 7?.
A function is a mapping from domain to range. The domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)
What is domain and range of a function?Domain is the set of values for which the given function is defined.Range is the set of all values which the given function can output.One method of finding the domain of a function is to start by finding the values for which it isn't defined.
Assuming that the function [tex]y = \sqrt{x+6} - 7[/tex] is defined for only real numbers, then, as we know that:
[tex]\sqrt{x}[/tex] exists only if x is non-negative, which means for [tex]\sqrt{x+6}[/tex] to be defined, we need
[tex]x + 6 \geq 0\\x \geq -6[/tex]
No other way is there for the function to be non-existing.
Thus, the values on which the function is defined is all real numbers bigger or equal to -6. This is the domain of the given function.
Thus, the domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

Signs of trig functions:
Answer:
Step-by-step explanation:
Each one of the trig functions is plus in two quadrants.
The sin(theta) is plus in 2
The Tan(theta) is plus in 3
The cos(theta) is plus in 4
Rule: if the trig function is not plus, then it is minus.
So if Tan (theta) is minus it means theta is in quad 2 or quad 4
So in this case theta is either in quad 2 or quad 4.
The sin is plus, that means that theta is in quad 2.
An isosceles triangle has side lengths of 16, an altitude of x, and a base of 2x. Find the length of the base.
Answer:
Step-by-step explanation:
Since the altitude of an isosceles triangle drawn from its vertex angle bisects the base, we can use the pythagorean theorem to say that:
16^2 = x^2 + x^2
256 = 2x^2
128=x^2
x = 8sqrt2.
so the base has a length of 16sqrt2.

Karl has 200 coins in a jar. Nickles make up 10% of the coins in the jar, pennies make up 60% of the coins in the jar. All the coins in the jar are pennies, nickles, or dimes.
1) How many of the coins are nickles?
2) How many of the coins are dimes?
3) If Karl removes 100 pennies from the jar, then what percent of the remaining coins in the jar would be pennies?
PLEASEEEE HELP ASAP!!!!!!!!!!!! IT WOULD MAKE MY LIFE!!!
Answer:
We know that there are 200 coins
10 percent of the coins in the jar are nickels.
60 percent of the jar are pennies.
So how many nickels, dimes, and pennies.
Let’s break this down.
So 200 coins and 60 percent are pennies.
so lets find pennies first, so remeber percent means “out of a hundred” so 60 percent is really 60/100 or 0.6. Multiply 0.6 by 200 and you’d get 120 pennies.
120 pennies
Now 10 percent fo the coins in the jar are nickels. Same thing, 10 percent is basically 10/100 or 0.1. 0.1 * 200 is 20.
(1) 20 nickels
Now we know that there are 120 pennies and 20 nickels. The remaining is 60 coins left which has to be dimes.
2) 60 dimes.
Now if Karl removes 100 pennies, what would the percentage be. Now there were 120 pennies. So 120-100= 20. There’d be 20 pennies left.
We have to find the percentage but remember its 100 coins gone too so.
200-100=100
So it’s asking what percent of 100 is 20. Which should be pretty simple to look at (only in this situation or any other easily definable benchmarks).
3) 20 percent are pennies.

Tiana is 25 years old. She lives with a roommate and a dog. She has worked at a fancy restaurant for 6 months. She works 40 hours per week and makes $2.13 per hour. She usually serves 45 tables per week. The average bill at the restaurant is $130 per table, and she typically receives a 20% tip. How much does she make in a typical week?
Answer:
$1,255.5 dollars per week
Step-by-step explanation:
40Hr * $2.13 = $85.2 per week from hours alone
$130 * 0.20 = $26 tip per table
$26 * 45 tables = $1,170 in tips
$85.2 + $1,170 = $1,255.2 per typical week

There is now a 20% discount on the stuffed animals. What is the sale price of each stuffed animal?
Answer:
$20 for each stuffed animal
Step-by-step explanation:
[] The original price is $25, but it is 20% off.
100% - 20% = 80%
[] Now we can find 80% of $25.
-> First, 80% divided by 100 becomes 0.8, a decimal we can work with
25 * 0.8 = 20

Which statement about f(x) and its translation, g(x), is true? The domain of g(x) is {x | x > 6}, and the domain of f(x) is {x | x > 0}. The domain of g(x) is {y | y > 0}, and the domain of f(x) is {y | y > 6}. The asymptote of g(x) is the asymptote of f(x) shifted six units down. The asymptote of g(x) is the asymptote of f(x) shifted six units up.
The correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.
The given functions are;
F(x) = 7x
g(x) = 7x + 6
Parent functionA parent function is the simplest function that still satisfies the definition of a certain type of function.
We can see that 6 has been added to the function f(x) to get the function g(x).
We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.
Therefore, we will get g(x), when we will shift f(x) upward by 6 units.
Both functions are linear functions hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.
Hence, the correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.

an employee earns $31.20 after four hours and $54.60 after seven hours. What is the employees hourly rate of pay?
Answer:
$7.80 an hour
Step-by-step explanation:
$31.20/4 = 7.8
$54.60/7 = 7.8
Answer:
$7.80 per hour
Step-by-step explanation:
I know this equation might seem a bit complicated, but it's actually really simple. Just divide.
$31.20/4 = $7.80
Now we just have to make sure the second one matches.
$54.60/7 = $7.80
Since they both match, the hourly rate of pay is $7.80.

Is (4,2) a solution to this system of equations?
y = -x + 6
y = 2x - 4
Answer:
No
Step-by-step explanation:
substitute the x- coordinate of the point into both equations and if the value obtained is equal to the y- coordinate then the point is a solution.
y = - 4 + 6 = 2 ← true
y = 2(4) - 4 = 8 - 4 = 4 ≠ 2 ← false
Thus the point is not a solution to the system
