Solve the system of equations.
x - 2y- z = -6
-x+6y-3z = 18
2x−11y+5z = -33
1. Let's solve for x.
x−2y−z=−6
Step 1: Add 2y to both sides.
x−2y−z+2y=−6+2y
x−z=2y−6
Step 2: Add z to both sides.
x−z+z=2y−6+z
x=2y+z−6
Let's solve for y.
x−2y−z=−6
Step 1: Add -x to both sides.
x−2y−z+−x=−6+−x
−2y−z=−x−6
Step 2: Add z to both sides.
−2y−z+z=−x−6+z
−2y=−x+z−6

maria's age is 3 years more than twice george's age.Which expression represents george's age in term of maria's?
Answer:
m-3 = g
2
OR
(m-3) ÷ 2 = g
Step-by-step explanation:
m = Maria
g = George
m = 2g + 3
We need g by itself
Since it is + 3 we can get rid it by doing -3 on both sides to end up with:
m-3=2g
To get rid of 2 we divide on both sides to end up with:
m-3 = g

HELP 40 POINTSS!! Use the following figure to answer BOTH parts the question.
a) Describe in words a sequence of transformations that maps ∆ABC to ∆A''B''C''.
b) Write an ordered-pair rule for each transformation in the sequence.
This questions have been solved in three steps showing the sequence of transformation that maps ∆ABC to ∆A''B''C''.
As per the question statement, we are supposed to describe in words a sequence of transformations that maps ∆ABC to ∆A''B''C''.
Before solving the question, we need to know about the coordinates of vertices of ∆ABC , which is as follows:
[tex]A(-5,3)[/tex] , [tex]B(-2,3)[/tex] and [tex]C(-4,1)[/tex]
Now coordinates of vertices of ∆A''B''C'' are as follows:
[tex]A"(8,-2)[/tex] , [tex]B"(5,-2)[/tex] and [tex]C"(7,0)[/tex]
Step 1: Shifting the ∆ABC four units vertically down so that the edge [tex]AB[/tex] lies on the [tex]x-axis[/tex]
Step 2: Shifting the ∆ABC ten units in horizontally right direction.
Step 3: Inverting the ∆ABC by [tex]180[/tex]° on the same axis
Step 4: Rotating the ∆ABC by [tex]180[/tex]° hence the new ∆A''B''C'' is mapped.
This question is a classic example to practice the coordinate geometry.
Sequence of transformations: A series of transformations or a composition of transformations is what results when two or more transformations are joined to create a new transformation.Coordinate geometry: By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.

A circle has a diameter with endpoints

M(-5, -4) lies on the diameter
What is the distance from A to M (Round to 2 decimal place
What is the distance from B to M (Round to 2 decimal places)
By using the Pythagorean theorem, both the distance from A to M and the distance from B to M are approximately equal to 8.25 units.
How to calculate distances in line segmentsDiameters are line segments whose endpoints lie on the same circumference and whose midpoint is the center of the circle associated to that circumference. In this problem we know the locations of the endpoints (points A and B) and a third point (point M) inside the diameter, and based on all this information we must determine the distances between points A and M and points B and M.
Each case can be found by using the Pythagorean theorem in the following form:
Points A and M
AM = √[[- 5 - (- 3)]² + [- 4 - (- 12)]²]
AM = 2√17
AM ≈ 8.25
Points B and M
BM = √[[- 7 - (- 5)]² + [4 - (- 4)]²]
BM = 2√17

The solution to the inequality p + 3.6 > −5.8 is p ∈ (-9.4, ∞) the number line (B) represents the solution set to the inequality.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The inequality is:
p + 3.6 > −5.8
After simplification:
p > -5.8 - 3.6
p > -9.4
The number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.
After plotting on the number line:
p ∈ (-9.4, ∞)
Thus, the solution to the inequality p + 3.6 > −5.8 is p ∈ (-9.4, ∞) the number line (B) represents the solution set to the inequality.

D
Answer:
54°
Step-by-step explanation:
Given BD bisects ∠ABC, which means it divided the angle into two equal parts, we can write the following equation to find the value of x, then the measure of ∠ABC:
9x = 8x + 3 subtract 8x from both sides
x = 3
The measure of ∠ABC = ∠ABD + ∠DBC
∠ABC = 9x + 8x + 3 add like terms
∠ABC = 17x + 3 replace x with 3
∠ABC = 17*3 + 3 and

Brand B offers a similar set for a list price of $425 less a 42% trade discount.If you order 500 dozen sets of the bowls, how much money (in $) will be saved by using the lower-priced vendor?
The amount of money in dollars I can save by using the lower-price vendor is 6750 dollars.
What is percentage?A percentage is a value per hundredth.
Brand A offers a list price of $400 per dozen for microwavable serving bowls and I want to order 500 dozen.
∴ The listed price I have to pay is (500×400) = 200000 dollars.
Given brand A offers a 35% of trade discount, So the actual price I have to pay is 65% of the listed price which is,
= (65/100)×200000 dollars.
= 130000 dollars for 500 dozens.
Similarly, brand B has a list price of $425 for a dozen and offers a 42% trade discount, So the price of 500 dozen microwavable serving bowels for the trade will be,
= (58/100)(425×500) dollars.
= 123250 dollars.
∴ The amount of money I will save is the lower the 6750 dollars.price vendor is

What is 617 rounded to the nearest ten
Answer:
620
Step-by-step explanation:
617 rounded to the nearest ten = 620.
The number 617 when rounded to the nearest ten will be 620.
We examine the digit in the position of the one and decide whether it is closer to the previous ten or the next ten to round a number to the closest ten.
The digit in the ones place for the number 617 is 7. We round up to the next ten since 7 is bigger than or equal to 5, so we do.
The tens digit is raised by one and all the digits to its right are set to zero in order to round up to the following ten.
So, when we round 617 to the nearest tenth, we get 620.

»Nevaeh uses a gift card to buy a cup of coffee every morning. The table shows the amount of
money remaining on the card, y, as a function of the number of cups of coffee she buys, c.
The rate of change is -3 since each cup of coffee costs $3.
The amount of money on the gift card when Nevaeh received the card = y-intercept of the function = $30.
What is the Starting Value/Y-intercept of a Function?The starting value/y-intercept of any function is the initial value or the value of y when x is equal to 0.
In the given scenario, the starting value/y-intercept (b), is the amount of money that was on the gift card when Nevaeh received the card.
Given the following:
Rate of change (m) = -3
Find b, y-intercept by substituting a point, (3, 21) and m = -3 into y = mx + b:
21 = -3(3) + b
Add 9 to both sides
21 + 9 = -9 + b + 9
30 = b
b = 30
Therefore, the amount of money on the gift card when Nevaeh received the card = y-intercept of the function = $30.
