The required solution in interval notation is [−5,2].
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Set of such values is called solution set to the considered equation or inequality.
Assuming we want to solve for x the result can vary.
We are given to find the solution to the following compound inequality in interval notation.
Inequality Form:
−5 ≤ x ≤ 2
Thus, the required solution in interval notation is [−5,2].

Hello Guys will ya'll pls help me with these
quiestions...?
Answer:
I'll help you with this so reflections is not hard.
For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).
For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).
sign is basically + or - if need to know.

the number of employees for a certain company had been decreasing each year by 8%. If the company currently has 860 employees and this rate continues, fund the number of employees in 19 years.
Answer:
approximately 684 employees
Step-by-step explanation:
So this is an exponential equation since there is a dividing decrease, not just subtracting. The standard equation is,
[tex]y = a(b)^{x} [/tex]. [tex]a[/tex] is initial value (860 employees) and [tex]b[/tex] is the change [tex]-8%[/tex] or [tex]0.92[/tex]. The [tex]x[/tex] would be the period of time, [tex]19[/tex]. This equation would be [tex]y = 860(0.92)^{19} [/tex].
After solving, the equation would become the following: [tex]y = 860(0.92)^{19} = 176.387242442≈176[/tex]. After subracting the number of lost employees from orginal employees ([tex]860-176=684[/tex]), we see that the company will have approximately 684 employees left after 19 years.

What’s the X coordinate of the vertex
Step-by-step explanation:
f(x) = (x + 3)(x - 5)
In a Quadratic curve, the x-coordinate of the vertex is equidistant to the x-intercepts. (If they exist)
In f(x), our x-intercept are x = -3 and x = 5.
=> (-3 + 5)/2 = 1.
Hence the x-value of the vertex is 1.

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.
(6x - 6.3) divided by 3
Step-by-step explanation:
We can represent the terms like this:
6x = 3 * 2x6.3 = 3 * 2.1Therefore, (6x - 6.3) / 3
= [(3)(2x) - (3)(2.1)] / 3
= 2x - 2.1.
Answer:
Terms of the equation is :---
6x/3 = 2x and 6.3/3 = 2.1
According to the given problem,
[tex] \frac{(6x - 6.3)}{3} = \frac{3(2x - 2.1)}{3} = \boxed{2x - 2.1} ✓\\ [/tex]

tan 235° = 2tan20°+ tan215°
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215

A random sample of Maxwell High School students showed that 7 out of every 12 students ride the bus to school . Maxwell High School has a total of 840 students . Based on the sample , how many students most likely ride the bus to school ?
Plsss fast
We would expect about 490 students to ride the bus to school based on the sample
What is random sampling?It is the way of choosing a number of required items from a population given.
Each item has an equal probability of being chosen.
We have,
If 7 out of every 12 students ride the bus to school, then the proportion of students who ride the bus is 7/12 or approximately 0.5833.
If we assume that this proportion holds true for the entire school, then we can estimate the number of students who ride the bus as follows:
Number of students who ride the bus = Proportion who ride the bus x Total number of students
Number of students who ride the bus = 0.5833 x 840
Number of students who ride the bus = 489.99
Since we cannot have a fractional number of students, we would round this estimate to the nearest whole number.
Thus,
We would expect about 490 students to ride the bus to school based on the sample
