Answer:
j + 3 ≤ 12
Hope this helps :)
Solution, Explanation, & Check part below
Step-by-step explanation:
1. Isolate variable by doing the inverse operation which is subtracting 3 on both sides of the equation.
j + 3 ≤ 12
- 3 - 3
j ≤ 9
j can be any number that is less than 9 or equal to 9.
Check:

positive & negative functions & the end behavior
Step-by-step explanation:
f(x) = 5|x - 1| - 5
f(x) will be positive that means >= 0, if
5|x - 1| - 5 >= 0
5|x - 1| >= 5
|x - 1| >= 1
that will be true for x <= 0 or x >= 2
f(x) will be negative for the other cases.
so, 0 < x < 2
f(x) is increasing in
[1, infinity)
the value "1" is for sure included, as it starts the increasing part.
f(x) is decreasing in
(-infinity, 1]
"1" is again included, because it ends the decreasing part.
end behavior means for x going to infinity and -infinity : in both cases f(x) goes to infinity.

Find the coordinates of ΔA'' B'' C'' after a reflection in the x -axis and a rotation of 180° about the origin if ΔABC has vertices A(-3,1),B(-2,3), and C(-1,0).
A(0,-3), B(3,-2), C(1, -1) (B) is the coordinates of ΔA'' B'' C'' after a reflection in the x -axis and a rotation of 180.
What does the term "coordinates" mean?
Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicses, scientists, and engineers frequently employ a variety of coordinate systems.A 180 degree clockwise rotation will change the coordinates as follows (x,y) --> (-x,-y)
A(-3, 0), B(-2, 3), C(-1, 0) -->
A(3, 0), B(2, -3), C(1, -1)
Reflection across the line y=-x will change the coordinates as follows (x,y) --> (-y,-x)

Edgar and Paul are playing video games. Edgar's score is 160 and he scores 5 points per second. Raul's score is 100 and he
scores 8 points per second. How long will it be before Raul takes the lead?
Answer:
21 seconds
Step-by-step explanation:
First let's find out how long it would take for them to have the same score.
160 + 5s = 100 + 8s
160 = 100 + 3s
60 = 3s
20 = s
Since it takes 20 seconds to get the same score and Raul get's more points every second, it would take 21 seconds for Raul to take the lead.

Help on solving this quadratic equation.
The discriminant of the quadratic equation is q · (q + 8) < 0. The solution set of this inequality is (0, - 8).
How to determine the family of constants associated to non-real roots of a quadratic equation
The nature of the roots of quadratic equations of the form a · x² + b · x + c = 0 can be inferred by the understading of its discriminant under the following condition:
b² - 4 · a · c < 0
Where a, b, c are the coefficients of the polynomial.
If we know that a = 2 · q, b = q and c = - 1, then the equation of the discriminant is:
q² - 4 · (2 · q) · (- 1) < 0
q² + 8 · q < 0
And by algebraic handling, we find the set of possible values of q:

Canon borrows $3,000 at a yearly simple interest rates of 1.6% for 2 years how much does he owe in interest and how much does he need to pay back in all
Interest is Rs.96 and Total amount payback is Rs.3096.
Principal (P) = Rs.3000
Rate of interest (R) = 1.6%
Number of years (N) = 2 yrs
Simple interest = PNR/100
= (3000*1.6*2)/100

=3096Rs
The principal, or initial balance of your account, is where interest is calculated. This could be the initial sum of a loan or an investment. The simplest way to compute interest is as a percentage of the principal .Only relatively short-term loans frequently include one-time basic interest charges. Interest is frequently paid on a daily, monthly, quarterly, or annual basis for loans with longer terms. In that scenario, interest would be consistently earned.
Hence, the interest for the above principle is 96Rs and the total amount to be payback is 3096Rs.

A standard 1 kilogram weight is a cylinder 54.5 mm in height and 53.0 mm in diameter. what is the density of the material?
The density of the material is 0.4 kg/cubic cm.
Given that:-
Height of the cylinder = 54.5 mm
Diameter of the cylinder = 53.0 mm
Weight of the cylinder = 1 kg
We have to find the density of the cylinder.
We know that,
Density = mass/volume
Here, mass = 1 kg
We know that,
Volume of a cylinder = [tex]\frac{1}{3} \pi r^2 h[/tex]
Where,
r is the radius of the cylinder, and
h is the height of the cylinder
Here, h = 54.5 mm, and
r = 53/2 = 26.5 mm
Hence,
Volume of cylinder = (1/3)*(22/7)*(26.5)(26.5)*54.5 ≈ 2566.088 ≈ 2566 cubic mm. = 2566/(10*10*10) cubic cm = 2.566 cubic cm

Two men are pushing a broken down car, mass 1800 kg, along a horizontal road with a combined horizontal force of 1000n. at one instant the car accelerates at 0.25m/s^". what is the value of frictional force acting on car at instant
When 2 men pushes car with mass 1800 kg and their combined horizontal forces are 1000 N, then frictional force acting on the car is 550 N.
The situation can be depicted in the attached picture. F1 and F2 are the horizontal forces of both men, while Fr is the frictional force. Remember that a frictional force is always the opposite of the direction of velocity.
Apply the 2nd Newton law of motion:
∑F = m.a
Where:
∑F = resultant of forces
m = mass of object
a = acceleration
In this situation, ∑F = F1 + F2 - Fr
The given parameters:
m = 1800 kg
a = 0.25 m/s²
F1 + F2 = 1000 N
Substitute these parameters into the 2nd Newton law:
F1 + F2 - Fr = m.a
1000 - Fr = 1800 . (0.25)
1000 - Fr = 450
