Is (2,12)(2,12)left parenthesis, 2, comma, 12, right parenthesis a solution of the system?
The solution to the given system of linear equations is x = -2 and y = -8. That is, (-2, -8).
Solving system of linear equationsFrom the question, we are to determine the solution to the given system of linear equations.
The given system of linear equations is
y = 5x + 2 ---------- (1)
4x - y = 0 ---------- (2)
Substitute equation (1) into equation (2)
4x - y = 0
4x - (5x + 2) = 0
4x - 5x -2 = 0
-x -2 = 0
-2 = x
x = -2
Substitute the value of x into equation (1)
y = 5x+ 2
y = 5(-2) + 2
y = -10 + 2
y = -8
Hence, the solution is x = -2 and y = -8

To solve the following inequality for x.
-26 + 13z + 2 > 2 132
Since there is no x in this I'm assuming we are looking for z
Step 1: Simplify both sides
15r - 26 > -13z + 2
Step 2: Add 13z to both sides
15r - 26 + 13z > -13z + 2 + 13z
28 - 26 > 2
Step 3: Add 26 on both sides
28 - 26 + 26 > 2 + 26
28z > 28
Step 4: Divide both sides by 28z / 28 > 28 / 28
z > 1

What is the transformation of a function?A function ix transformed when the graph of the function is translated, resized or reflected.
The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d
Where;
a indicates the graph of the function is dilated vertically
b indicates a dilation horizontally
c indicates a translation horizontally
d indicates a vertical translation
The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation
In a vertical translation of the form f(x) ± d
When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d
When d < 0, the graph of f(x) is moved down d units to get f(x) - d
The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3

Applying the centroid theorem, the missing measures are:
FM = 22
A.F = 66
CM = 36
ME = 18
MB = 46
DB = 69
What is the Centroid Theorem?The centroid theorem states that the distance from the centroid of the triangle to the opposite vertex is equal to one-third of the length of the segment that connects the midpoint of a side of a triangle to the opposite vertex.
Given:
AM = 44, CE = 54, and DM = 23, where M is the centroid of the triangle, thus:
FM = 1/3(FA) = 1/3(AM + FM)
Substitute
FM = 1/3(44 + FM)
3FM = 44 + FM
3FM - FM = 44
2FM = 44
FM = 44/2
FM = 22
A.F = AM + FM = 44 + 22
A.F = 66
CM = 2/3(CE)
CM = 2/3(54)
CM = 36
ME = CE - CM = 54 - 36
ME = 18
MB = 2/3(DB) = 2/3(DM + MB)
MB = 2/3(23 + MB)
3MB = 2(23 + MB)
3MB = 46 + 2MB
3MB - 2MB = 46
MB = 46
DB = DM + MB = 23 + 46

Alice, Ben and Charlie share $213
The ratio to Alice's share to Ben's share is 4:3
The ratio to Ben's share to Charlies share is 8:5
How much does Ben get?
After finding the ratio for each person, Ben will get $72
What is a Ratio?
A ratio shows the relative sizes of two or more values. Ratios can be shown in different ways:
using the ":" to separate example valuesusing the "/" to separate one value from the totalas a decimal, after dividing one value by the totalas a percentage, after dividing one value by the totalIt was given that Alice, Ben and Charlie are to share $213.
Ratio of Alice's share to Ben = 4 : 3
Ratio of Ben's share to Charlie = 8 : 5
Combining these ratios, their shared item (Ben's share) must be the same in each ratio.
Taking Alice's share to Ben, 4 : 3 and multiplying both parts by 8 to get an equivalent ratio, we have:
Alice : Ben = 4(8) : 3(8) = 32 : 24
Likewise, taking Ben's share to Charlie, 8 : 5 and multiplying both parts by 3, we have:
Ben : Charlie = 8(3) : 5(3) = 24 : 15
Combining these ratios, we have:
Alice : Ben : Charlie = 32 : 24 : 15
Adding the ratios together, we have: 32 + 24 + 15 = 71
If the money to be shared is $213, Ben's share will be:
[tex]\frac{24}{71}[/tex] × [tex]$213[/tex] = 72

HELPPP so the man bought a tv worth $1,700, and then each week he continued to spend $700 weekly WHAT IS THE EXPRESSION???? HELP (variable is X)
HELP
Answer: 700x+1700
This represents the total amount spent over the x weeks that have gone by.
===========================================
Explanation:
x = number of weeks
700x = amount spent over those x weeks ($700 per week)
700x+1700 = total amount spent when adding on the $1700 tv.
------
An example:
Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.
Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.
I recommend trying out other values of x to get a better idea of what's going on.

Step-by-step explanation:
Let the first integer be A; then the five consecutive integers are A, A+1, A+2, A+3, and A+4.
If the sum of the first three equals the sum of the last two, then A + (A+1) + (A+2) = (A+3) + (A+4)
