8 is not an element of set A since all the elements must be greater than 8. 8 ∉ A is correct.
Sets and valuesGiven the following set of values
U = {x|x is a real number}
A = {x|x ∈ U and x + 2 > 10}
B = {x|x ∈ U and 2x > 10}
The equivalent elements of the sets are:
U = {real numbers}
A = {x > 8}
B = {x > 5}
From the set above, we can see that 8 is not an element of set A since all the elements must be greater than 8.

For a certain triangle ABC, if a line intersects AC at D, intersects AB at E, and is parallel to CB, would the proportion AE | AD = EB | DC be accurate? Explain your answer.
The given proportion of triangle ABC as AE/AD = EB/DC is; Not Accurate
Understanding Basic proportionality theorem(Thale's Theorem)This theorem states that If a line is drawn parallel to one side of a triangle, then it cuts other two sides proportionally.
Thus, In ΔABC, DE || BC
By Thales theorem, we can say that;
AD/DB = AE/EC
Rearranging we can arrive at;
AE/AD = EC/DB
When we simplify further by adding 1 to both sides, we will get;
AD/AB = AE/AC
Thus, the given proportion is not accurate

Which of the following represent the values of x, y, and z to the nearest hundredth?
Answer:
Step-by-step explanation:
y² = 5.66 × 5.66 ⇒ y = 5.66
x = z = 5.66√2 ≈ 8.00
The values of x, y and z in the given triangle are 8, 5.66 and 8.
What are triangles?Triangles are a type of a polygon having three sides and angles.
Given is a triangle, having some unknown variables, we need to find their values,
So,
According to the figure we can say that the triangle is an isosceles triangle because the median is perpendicular to the base and dividing it into equal parts.
Therefore,
y² = 5.66 × 5.66 ⇒ y = 5.66
x = z = 5.66√2 ≈ 8.00
Hence, the values of x, y and z in the given triangle are 8, 5.66 and 8.

The zeros of the function y = -5x - 7 is at x = -7/5
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given the equation:
y = -5x - 7
The zeros of the function is at y = 0, hence:
0 = -5x - 7
-5x = 7

Find the least common denominator. Then express each fraction using the least common denominator.
5/12 and 4/18
Answer:
5/12 = 15/364/18 = 8/36Step-by-step explanation:
The least common denominator can be found as the product of the denominators, divided by their greatest common factor:
LCD = (12)(18)/6 = 36
This is 3 times 12, so
5/12 = (5/12)(3/3) = 15/36
and it is 2 times 18, so
4/18 = (4/18)(2/2) = 8/36

Maggie has $16 to spend on lunch for the week she has already spent four dollars which inequality statement shows how much more money Maggie has left to spend for the week
Answer:
x ≤ $12
Step-by-step explanation:
Since Maggie has $16 to spend for the week, she can spend less than $16 or exactly $16. Thus, the inequality used would be ≤, which can be read as 'less than or equal to'.
Let the amount of money she has left to spend for the week be x.
Total spending for the week ≤ $16
$4 +spending for the rest of the week ≤ $16
$4 +x ≤ $16
Subtract both sides by $4:
x ≤ $16 -$4
x ≤ $12

Step-by-step explanation:
well, you put the input term into the place of the original variable (as with any actual constant value) :
f(4x-1) = 2(4x-1) - 5 = 8x - 2 - 5 = 8x - 7
