Answer:
x = 10
Step-by-step explanation:
1. Because this is a right angle (an angle with 90°), 54 + 3x + 6 = 90.
2. (Solving equation above)
Step 1: Simplify both sides of the equation.
[tex](3x)+(54+6)=90[/tex] [tex]3x + 60 = 90[/tex]Step 2: Subtract 60 from both sides.
[tex]3x + 60 - 60 = 90 - 60[/tex] [tex]3x = 30[/tex]Step 3: Divide both sides by 3.
[tex]\frac{3x}{3} =\frac{30}{3}[/tex] [tex]x = 10[/tex]Step 4: Check if solution is correct.
[tex]54 + 3(10)+6=90[/tex] [tex]54+30+6=90[/tex] [tex]84+6=90[/tex] [tex]90=90[/tex]Therefore, x = 10.

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.

The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answers
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.
6. Tell whether the lines are parallel, perpendicular, or neither. *

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

Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p

do logarithmic functions have horizontal asymptotes?
Answers
9514 1404 393
Answer:
not generally
Step-by-step explanation:
The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.
__
A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...
f(x) = 1/log(x)
has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)

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)

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

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

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.
