An order relationship with greater than, greater than or equal to, less than, or less than or equal to between two algebraic expressions. The solution of inequality -3x+4≥10 is x≤-2
What is Inequality?An order relationship with greater than, greater than or equal to, less than, or less than or equal to between two algebraic expressions.
The given inequality is
-3x+4≥10.
To solve the above inequality
Subtract -4 from both sides.
-3x+4-4≥10-4
+4 and -4 we get zero.
-3x≥6
Divide by 3 on both sides
-x≥2
When negative sign is multiplied on both sides, the greater than or equal to symbol changes to lesser than or equal to.
x≤-2
Hence x≤-2 is solution for -3x+4≥10.

Answer: 8 days
Step-by-step explanation:
1) Set up an equation. Let x be the day
3,500 >= 2(816) + x(100+95)
The 816 is just two times (Plane ticket back and forth) so it doesn't go into the x. 100 and 95 do as it is one day.
2) Solve the equation
3,500 >= 2(816) + x(100+95)
1868 >= 195x
9.57 >= x
3) Rounding
Since the x has to be less than 9.57, our next option is 8

6. The net profit margin ratio for two companies is modelled by
by
8x
3x - 1
for company B where x is the number of items sold in thousands. Sam is trying
5x
2x - 3
for company A and
to decide in which company he should buy stock so he is going to compare the ratios. He
has researched both companies and he knows that each produces over 25 000 items per
month.
(C: 25)
a) He wants to find out if theywould ever have the same ratio and if so when. How would
you tell him how to find this mathematically? What should he have found as his answer
to the question?
b) Which company has a higher ratio for 30 000 items sold? What is that ratio to the
nearest thousand for both companies?
We deduce that the ratios would be the same for 2111 sales.
Consequently, it is obvious that firm B has a better ratio for 30000 sales.
What is the concept of ratio and proportion?Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
if A = B then
5x/(3x-3) = 8x/(3x-1)
24x^2 - 24x = 15x^2 - 5x
9x^2 - 19x = 0
x(9x - 19) = 0
x = 0 , not possible because zero number of sales is not possible
or
x = 19/9 thousands = approximately 2111
Therefore, we conclude 2111 sales, the ratios would be the same.
For the second part :
we substitute the value of x as 30000 in the equations to see which ratio is bigger
8*30000/3*30000-1=2.666 or 2.7
5*30000/2*30000-3=2.5
Therefore we can clearly see that the company b has a higher ratio for 30000 sales.

Rachel and Nicole are training to run a half-marathon. Rachel begins by running 30 minutes on the first day of training. Each day she increases the time she runs by 3 minutes. Nicole’s training follows the function f(x)=5x+30, where x is the number of days since the training began, and f(x) is the time in minutes she runs each day. What is the rate of change in minutes per day for the training program that has the slowest rate of change?
............ minutes per day
The slowest rate of change that is the slowest for the training program is: 3 minutes per day.
What is the Rate of Change of a Function?In a given function that is expressed in slope-intercept form as .f(x) = mx + b, the rate of change of the function is represented as "m", while the starting or initial value is represented as "b" in the equation.
Given that Rachel increases the time she runs by 3 minutes for each day, then, the rate of change per day for the training program or Rachel is 3.
Given that the function .f(x) = 5x + 30 represents the minutes Nicole runs per day in the training program, then the rate of change is represented as "5" in the equation. This means that each day, Nicole increases her time of running by 5 minutes as compared to 3 minutes per day that Rachel increases her daily runs.
3 minutes per day is slower than 5 minutes per day, in order words, the slowest rate of change is therefore: 3 minutes per day.

What is the slope of a line perpendicular to the line whose equation is 6x+8y=−128. Fully simplify your answer.
The slope of a line perpendicular to the line 6x + 8y = -128 is 4/3.
Given,
The equation of a line = 6x + 8y = -128
We have to convert this into standard form of linear equation, y = mx + b :
So,
6x + 8y = -128
Add -6x to both sides,
6x + 8y - 6x = -6x - 128
Now,
8y = -6x - 128
Divide 8 on both sides
8y/8 = (-6x - 128) / 8
We get,
y = -6/8x - 16
Here, this is in standard form of linear equation.
Here slope of line, m₁ = -6/8
We have to find the slope of line(m₂) which is perpendicular to the given line.
If the line is perpendicular, the slope(m₂) will be the negative reciprocal of the slope(m₁) of the given line.
That is,
Slope of line, (m₂)= -(m₁) = - (-8/6) = 8/6 = 4/3
That is, the slope of the line which is perpendicular to the given line is 4/3.

Rate of change is $35.
Define rate of change.The momentum of a variable is represented by the rate of change, which is used to mathematically express the percentage change in value over a specified period of time. Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change. The rate of change is expressed by a line's slope. It is frequently used while discussing momentum and is typically expressed as a ratio of one variable's change to another's corresponding change. This ratio is graphically represented by a line's slope.

Then, to solve the exercise, we need to know the slope of each line. The slope of a line is the measure of the steepness of a line.
The graph shows that the red line has a greater steepness than the blue line. Thus, the lines have different slopes. Also, two lines are parallel if they have the same slope. Since these lines have different slopes, they are not parallel.
Therefore, student B is correct because the lines are not parallel, so they will intersect.

Option A, -9x - 2 = 14x is the required equivalent equation for the equation 5x - 2(7x + 1) = 14x.
What are equivalent equations?
Equations with the same answer or solution are said to be equivalent. Comparisons between linear equations are common. When graphed, linear equations result in straight lines with a slope and a y-intercept. The characteristics that make a linear equation linear are crucial in establishing if two linear equations are equivalent. Although it may not seem like it at first, there are mathematical procedures to determine whether the equivalent equations will have the same solution.
To get equivalent equation of the given equation, we need to simplify it.
So, given equation
5x - 2(7x + 1) = 14x
Lets multiply -2 with 7x+1, we get
5x-14x-2=14x

Finding the functions to solve the problem, we have:
