Answer:
LN=12
Step-by-step explanation:
3x-9=x+1 add 9 to both sides
3x=x+10 subtract 1x on both sides
2x=10 divide by 2
x=5
3(5)=15-9=6

Identify the domain and range of the function. Enter your answers as numbers in the boxes; do not include units. Enter the range values in ascending order separated by commas. Age Admission Price under 5 free 5–17 $25 18–64 $40 65 and over $35 What is the domain?
Given that:
The tables values which represents Age and Admission Price is
Age Admission Price
under 5 free
5–17 $25
18–64 $40
65 and over $35
To find:
Domain and range of the function.
Solution:
Domain is the set of input values.
Here, domain is age because age is an independent variable.
Age cannot be negative, so
[tex]Domain:\{Age\geq 0\}=[0,\infity)[/tex]
Therefore, the domain is all number greater than or equal to 0.
Range is the set of input values.
Here, range is Admission Price because Admission Price is a dependent variable.
Admission Prices are free (i.e., 0), $25, $40 and $35. So
[tex]Range:\{0,25,35,40\}[/tex]
Therefore, range is {0,25,35,40}.
In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town, what are the odds against selecting someone who commutes by bicycle?
Answer:
So if 25% of the people go to work by bicycle then that means that 75% of people go to work by other means of transportation.
Therefore the odds against selecting someone who commutes by bicycle are 75% or 75/100 or 0.75.
Step-by-step explanation:
The odds against selecting someone who commutes by bicycle are 75%
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town.
25% of the people go to work by bicycle then which means that 75% of people go to work by other means of transportation.
Therefore the odds against selecting someone who commutes by bicycle are 75% or 75/100 or 0.75.

Which of the following would eliminate the variable on the left side of the given equation? 36 - 19w = -6w + 41 add -19w add 19w add 6w add -36
Answer:
[tex]$w=-\frac{5}{13} $[/tex]
Step-by-step explanation:
[tex]36 - 19w = -6w + 41[/tex]
Add 19w in both sides
[tex]36 - 19w+19w = -6w+19w + 41[/tex]
[tex]36 = 13w + 41[/tex]
Add -41 both sides
[tex]-5 = 13w[/tex]
Divide both sides by 13

Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.
Answer:
A because
Step-by-step explanation:
Which the following steps is included in the construction of a perpendicular line through a point on a line? Connect arcs that are above and below the given line with a straightedge. Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.
so the answer is A
The step included in the construction of a perpendicular line through a point on a line is the option:
Connect arcs that are above the original line with a straightedge
The reason for the above selection is as follows:
The steps in the construction of a perpendicular line through a point on a line include
The compass needle is placed at the point through which the perpendicular line is to pass and two arcs or equal radius, r, are drawn on either side of the point crossing the line
Increase the compass width to more than the radius, r, above, place the compass needle at the intersections of the arc and the line drawn above and draw an arc either above or below the line
Repeat the above step from the other intersection of the arc on the other side of the point on the line and draw another arc that intersects the arc in the above step, above or below the line
With the straightedge, draw a line from the given point that passes through the intersection of the arcs above or below the line to complete the construction of a perpendicular line passing through a point on a line
Therefore, the included step in the construction of a perpendicular line through a point is; Connect arcs that are above the original line with a straightedge

what is the value of x ?
Answer:
x = 70
Step-by-step explanation:
Both angles must add up to 180°, by the definition of a line.
Step 1: Set up equation
x - 31 + 2x + 1 = 180
Step 2: Solve for x
3x - 30 = 180
3x = 210
x = 70

Destin walked 2km and Jane walked 4,000 ft. What is the approximate combined distance they walked? Note: 1 Foot (ft) is equal to 0.0003048 kilometer (km).
A 1 of a mile 5
B 50 yards
C 2 miles
D) 5 kilometers
Answer: Option C.
Step-by-step explanation:
The data is:
Destin walked 2km
Jane walked 4000ft.
Let's write both of those in the same units.
The data given is:
1ft = 0.0003048km.
and 4000ft is 4000 times that:
4000ft = 4000*1ft = 4000*0.0003048km = 1.22km
Then if we add those, we get:
Total distance = 2km + 1.22km = 3.22km
So we can already discard option D.
Now, we know that:
1km = 0.6214 miles.
then 3.22 km is 3.22 times that amount:
3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles
The correct option is C.

Solve for y:
3x - 5y = 20
Steps to solve:
3x - 5y = 20
~Subtract 3x to both sides
-5y = 20 - 3x
~Divide everything by -5
y = -4 + 3/5x
Best of Luck!
The equivalent value of the expression is y = ( 3x - 20 ) / 5
Given data ,
Let the equation be represented as A
Now , the value of A is
3x - 5y = 20
On simplifying the equation , we get
3x - 5y = 20
So , the left hand side of the equation is equated to the right hand side by the value of 20
Adding 5y on both sides , we get
3x = 20 + 5y
Subtracting 20 on both sides , we get
5y = 3x - 20
Divide by 5 on both sides , we get
y = ( 3x - 20 ) / 5
Therefore , the value of y = ( 3x - 20 ) / 5
Hence , the expression is y = ( 3x - 20 ) / 5
