Because you use trial and error to see what x is and it says integet meaning 1,2,3,4,5,6... and their opposites.
Answer:
x ≈ 5 using math and x ≈ 4 using trial and error
Step-by-step explanation:
[tex]6^x = 3800[/tex]
[tex]x = log_{6}*3800[/tex]
x ≈ 4.6 ≈ 5
Hope this helped!
-----------------------------------------------------------------------------------------------
Trial and Error:
6 ^ 4 = 1276
6 ^ 5 = 7776
3800 is closer to 1276, so x = 4
6. Tell whether the lines are parallel, perpendicular, or neither. *
Line 1: (-3,-1) and (-7,-2)
Line 2: (2.-1) and (8,4)
Parallel with a slope of 1/4
Parallel with a slope of 5/6
Perpendicular with a slope of 1/4 and
Perpendicular with a slope of 1/4
Neither, slopes are 1/4 and 5/6
O
Neither, slopes are 3/10 and 1/2
Answers
Answer:
Neither, slopes are 1/4 and 5/6
Step-by-step explanation:
Let's find the slope for Line 1: (-3,-1) and (-7,-2)
m1 = (-2+1)/ (-7+3)
= -1/-4
=1/4
Line 2: (2.-1) and (8,4)
m2= (-4+1)/ (8-2)
= -3/6
= - 1/2
These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is
Neither, slopes are 1/4 and 5/6

Joe is training for a marathon. He plans to run 4 miles every day (d). In order to feel prepared, his goal is to run at least 60 miles before the race.
Write an inequality to represent how many days he will need to run in order to meet his goal.
Answers
Answer:
Step-by-step explanation: 4x15 =60
The inequality which represents the number days Joe will need to to run in order to meet his goal is [tex]4d\geq 60[/tex].
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.
According to the given question.
Joe plans to run 4 miles every day.
And his goal is to run at least 60 miles.
Let Joe needs d days to run.
Therefore, according to the given condition the inequality which represents the number days Joe need to run in order to meet his goal is given by
[tex]4d\geq 60[/tex]
Hence, the inequality which represents the number days Joe will need to to run in order to meet his goal.

Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5

Answers
Answer:
[tex]9n - 12 \rightarrow \frac{1}{3} (9n - 12) \\ = \frac{3}{3} (3n - 4) \\ l = 3n - 4[/tex]
The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.
Solution:The perimeter of an equilateral triangle is 9n - 12.We know, perimeter of a triangle is the sum of the three sides of the triangle.Also, in an equilateral triangle, all the sides are equal.Therefore, the length of each side of the triangle
[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]
Answer:The length of each side of the triangle is 3n-4.

We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution

The following represents slopes of two lines. Which answer choice describes the two lines? m = 7 and m = -7
Answers
Answer:
m = 7 can also be y=7x+1 is positive and shows acceleration or ascending lines steep y axis 1 and x axis 0 ascending to 1 or above and when y = 7 x =1 see attached.
m = -7 is negative and shows deceleration of 1 as we add 1 here too. Or can be any number for y intercept see attached.
Step-by-step explanation:
The slopes of two lines are given as:
m = 7
m = -7
A line with a positive slope of 7 rises as it moves to the right, and a line with a negative slope of -7 falls as it moves to the right.
Therefore, the two lines have slopes that are opposite in sign and have the same magnitude. This means they are two straight lines that are mirror images of each other, reflected across the x-axis.
Graphically, they would look like this:

|
------ + ------ (m = 7)

Therefore, the two lines are parallel to each other and have a distance between them
