Answer:
|x - 13| = 5
Step-by-step explanation:
Think of absolute value as a distance. For example, |5| can be written as |5 - 0| = 5 since the distance between 5 and zero on the number line is 5. Also, |-5| which is the same as |-5 - 0| is also 5 since the distance between -5 and zero on the number line is 5.
Since you want an absolute value equation with solutions 8 and 18, think of which number is the same distance from both 8 and 18 on the number line? Find the average of 8 and 18, (8 + 18)/2 = 13. 13 is the same distance from both 8 and 18. 13 is 5 units away from both 8 and 18. Now you need an equation that is looking for the numbers x which are 5 units distance from 13.
|x - 13| = 5

How many different 7-digit positive integers exist? (Note that we don't allow "7-digit" integers that start with 0, such as 0123456; this is actually a 6-digit integer.)
There are 9,000,000 seven-digit positive integers.
Explanation:
For the first digit, we have 9 choices: 1, 2, 3, 4, 5, 6, 7, 8, 9.
For each remaining digit, we have 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Each choice is independent of the others. So, the number of total 7-digit positive integers is the product of all the numbers of choices for each digit.
hope it helps
need brainliest......
Since 0 cannot be put as the first digit, there are 9 choices for the first digit, and the next 6 digits have 10 choices. So, there are 9 × 10^6 = 9000,000 numbers.

Which equation would be used to find the cost C of a ticket after L losses? PLS HELPP
Answer:
Choice C
Step-by-step explanation:
If L represents the number of losses, and each loss decreases the total ticket price ($47.48) by $0.29, then the equation can be written as the following
47.48 - 0.29L
If you plug in any value, larger than 0, you will see that the price decreases by a constant rate of $0.29

Which trigonometric functions are undefined when x = 0?
The trigonometric functions that are undefined when x = 0:
cot(x) and cosec(x)
We need to write the trigonometric functions are undefined when x = 0.
We know that the trigonometric functions are : sine, cosine, tangent, cotangent, secant and cosecant.
For angle x the trigonometric functions would be,
sin(x), cos(x), tan(x), cot(x), sec(x), cosec(x)
We know that, when x = 0,
sin(0) = 0 and cos(0) = 1
tan(x) = sin(x) / cos(x)
So, tan(0) = 0
cot(x) = cos(x)/sin(x)
cot(0) = 1 / 0
cot(0) = undefined
Also, sec(x) = 1/cos(x)
so, sec(0) = 1
And cosec(x) = 1/sin(x)
so, cosec(0) = 1/sin(0)
cosec(0) = 1 / 0
i.e., cosec(0) = undefined
Therefore, the trigonometric functions that are undefined when x = 0:
cot(x) and cosec(x)

Solve the quadratic equation 3x^2+x-5=0
Give your answers to 2 decimal places.
Answer:
x= 1.13 or x= -1.45
Step-by-step explanation:
use the quadratic square root formula (-b±√(b²-4ac))/(2a) .
a= 3
b=1
c= -5
replace the variables with the numbers listed above and just work out.
x= 1.13 or x= -1.45
Answer:
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61
Step-by-step explanation:
3x^2+x-5=0
Using quadratic formula a=3, b=1, c=-5
x = -b ± √b^2 - 4ac / 2a
x = -(1) ± √(1)^2 - 4(3)(-5) / 2(3)
x = -1 ± √61 / 6
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

As it often happens, each family thinks that their neighbors (i.e. those families living in the squares with which their square shares a side) have better living units.

The illustration below is an example of a semi-regular tessellation.
A. True
B. False
The illustration below is a semi-regular tessellation is a false statement.
What is Tessellation?Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.
One geometric shape will not overlap with the other and there will not be any gaps in between.
There are regular tessellations as well as semi-regular tessellations.
Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.
Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.
Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.
It is actually regular tessellation.
Hence the statement that the illustration is semi-regular tessellation is incorrect.
