[tex] {x}^{2} - 4 \div x - 2[/tex]
Step-by-step explanation:
[tex]\dfrac{x^2-4}{x-2}[/tex]
Apply identity a²-b² = (a-b)(a+b)
So, it will be
[tex]\dfrac{(x-2)(x+2)}{x-2}[/tex]
Where x-2 gets cancelled from numerator and denominator.
Hence, x+2 is the answer.

What is the slope of the line that goes through the points (6,4) and (8,-2)?
Answer:
B: -3
Step-by-step explanation:
The points are given as; (6,4) and (8,-2)
Slope is given by the formula;
Slope = (y2 - y1)/(x2 - x1)
Slope = (-2 - 4)/(8 - 6)
Slope = -6/2
Slope = -3
y = 3x +4
y = -2
A method by solving systems of equations by adding or subtracting to eliminate a variable
Please answer this!!!
Answer:
x=5
Step-by-step explanation:
first multiply both sides by 12 and by 5 to get rid of your fractions
5(5x-1) = 12(x+5)
expand the brackets
25x-5=12x+60
minus 12x from both sides
13x-5=60
add 5 to both sides
13x=65
divide both sides by 13
x=5
hope that helps

Answer:
x = 4 and y = 1
Step-by-step explanation:
The given equations are :
2x+5y = 13 ...(1)
3x-2y = 10 ...(2)
We can use elimination method to solve the given equations.
Multiply equation (1) by 3 and equation (2) by 2.
6x+15y=39 ...(3)
6x-4y=20 ...(4)
Subtract equation (3) from (4).
6x-4y-(6x+15y) = 20-39
6x-4y-6x-15y = -19
-19y=-19
y = 1
Put the value of y in equation (1).
2x+5y = 13
2x+5=13
2x=8
x = 4
So, the solution of the given equations are x = 4 and y = 1.

6. Let f be the function defined by f(x)=1x2+9.
(a) Evaluate the improper integral ∫∞3f(x) dx, or show that the integral diverges.
(b) Determine whether the series ∑n=3∞f(n) converges or diverges. State the conditions of the test used for determining convergence or divergence.
(c) Determine whether the series ∑n=1∞(−1)n(en⋅f(n))=∑n=1∞(−1)n(n2+9)en converges absolutely, converges conditionally, or diverges.
Answer:
So you have a power of x^2, notice if you have a harmonic series, or if it looks familiar, which it should, hint (1/x) Now integrate: let u= x/3 dx=3dunow integral (1/u^2+1) recognize thats arcso you get a result of: arctan(x/3)/3+cIn a math class with 20 students, a test was given the same day that an assignment
was due. There were 12 students who passed the test and 13 students who completed
the assignment. There were 10 students who passed the test and also completed the
assignment. What is the probability that a student chosen randomly from the class
passed the test and completed the homework?
=1/2
The probability that a student chosen randomly from the class
passed the test and completed the homework is [tex]\frac{1}{2}[/tex].
What is probability?"Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen."
Given
Number of students in a math class = 20
Number of students who passed the test = 12
Number of students who completed the assignment = 13
Number of students who passed the test and also completed the
assignment = 10
Formula to find probability of an event
Probability = [tex]\frac{Number of Favorable Outcomes}{Total Number of Favorable Outcomes}[/tex]
The probability that a student chosen randomly from the class
passed the test and completed the homework
= [tex]\frac{Number of Students Passed the Test and Completed the Homework }{Total Number of Students}[/tex]
= [tex]\frac{10}{20}[/tex]
= [tex]\frac{1}{2}[/tex]
Hence, the probability that a student chosen randomly from the class
passed the test and completed the homework is [tex]\frac{1}{2}[/tex].
