Use the properties of equality to solve the equation 3x+2-x=11x+9. State which property justifies your first step and why you chose it. Check your solution
The first step we'll make is subtraction property of equality and we choose this property to separate the variables and contsnts.
What are the properties of equality?Facts regarding any two or more quantities connected by the equal sign are known as properties of equality.
There are four types of properties of equality.
Addition property, when two equal quantities are increased by a common value, the equality is preserved.
Transitive property of equality, entities that are equivalent to one another are also equivalent to one another.
Subtraction property, equality is maintained when a common term is subtracted from two equal terms.
Multiplying by a common term do not alter the equality, according to the multiplication property of equality.
Given, An equation 3x + 2 - x = 11x + 9.
The first step would be subraction property of equality.
We'll subtract 2 from each side of the equation.
3x + 2 - x - 2 = 11x + 9 - 2.
3x - x = 11x + 7.
We choose subraction property of equality to separate the vriables and the constants.

Answer:
From his starting point of 85 3/4, he descended 17 9/20 meters
Step-by-step explanation:
We want to know how much farther he went down from his starting point.
103 1/5 - 85 3/4
S
tart off by making the denominators of both the numbers the same.
103 1/5 - 85 3/4

2x + y = 7 3x -2y = -7 solve by substitution
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(1, 5)
Equation Form:
x = 1, y = 5
Brainliest Please!!
The solution for the given equations: x = 1 , y = 5.
What is substitution method?The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.
Given, equations
2x + y = 7 -------(a)
3x -2y = -7 -------(b)
Taking equation (a)
2x + y =7
y = 7 - 2x ------(c)
Substituting value of y in equation (b) from equation (c)
3x - 2(7 - 2x) = -7
3x - 14 + 4x = -7
7x = 7
x = 1
Putting value of x in equation (c)
y = 7 - 2 (1)
y = 5
Hence, x = 1 and y = 5 is the solution for the given equations 2x + y = 7 and 3x -2y = -7.

Answer:

Step-by-step explanation:
Line segment RS has endpoints R(– 2, 4) and S (– 4, – 1). Line segment R''S'' has endpoints R'' (3, – 3) and S'' (5, 2). Name the transformations that map line segment RS to line segment R''S''. reflection over the line y = x, followed by a translation (x, y) → (x + 1, y + 1) rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1) rotation of 90° counterclockwise about the origin, followed by a translation (x, y) → (x + 2, y + 1) translation (x, y) → (x + 1, y + 1), followed by a rotation of 180°counterclockwise about the origin
Answer:
Rotation of 180° about the origin,
Followed by a translation (x, y) → (x + 1, y + 1)
Step-by-step explanation:
Given
[tex]R = (-2,4)[/tex]
[tex]S = (-4,-1)[/tex]
[tex]R" = (3,-3)[/tex]
[tex]S" = (5,2)[/tex]
Required
Determine the transformations
From the list of given options (B) answers the question.
Rotation of 180° about the origin,
When a point (x,y) is rotated 180 about the origin, the new point becomes (-x,y)
So:
[tex]R = (-2,4)[/tex]
[tex]S = (-4,-1)[/tex]
becomes
[tex]R' = (2,-4)[/tex]
[tex]S' = (4,1)[/tex]
A translation (x, y) → (x + 1, y + 1)
This implies that 1 is added to the x and y coordinates
So:
[tex]R' = (2,-4)[/tex]
[tex]S' = (4,1)[/tex]
becomes
[tex]R" = (2 + 1,-4 + 1)[/tex]
[tex]R" = (3,-3)[/tex]
[tex]S"=(4 +1,1+1)[/tex]
[tex]S" = (5,2)[/tex]
I’m confused on how I can prove number 1 and 2, unless T is the median idk
Problem 1
We're given that QE = RW and QW = RE. This is given both in terms of symbols, and also visually in terms of the tickmarks. We have two pairs of congruent sides.
The third pair of sides is the overlapping shared segment of segment WE. So WE = WE by the reflexive property.
From here we use the SSS congruence property to conclude the proof that triangle QWE = triangle REW
==============================================
Problem 2
Segments BC and AE bisect each other. The term "bisect" means "to cut in half".
BC bisecting AE means AD = DE
AE bisecting BC means BD = DC
So we have two pairs of congruent sides. So far, we're on a similar path compared to problem 1. This time however, we'll use a pair of congruent angles instead of the third pair of sides.
Specifically we'll use the fact that
angle ADB = angle CDE
by the vertical angle theorem
Once we know that, we then use the SAS congruence theorem to prove triangle ABD = triangle ECD
To be honest, I'm not sure what you meant by "median", but we don't use any triangle medians here (none of the triangles shown have any medians drawn). You might be thinking of a previous problem.

What is the x-coordinate of point A in a triangle with vertexes in A (3, 5), B (6, -3) and C (-2, -2) after undergoing a translation of 5 units to the right and 2 units down?
Answer:
(8,3)
Step-by-step explanation:
if there is a words left and down on our question we will decrease a given number from the coordinates.
but if we have words like right and up in our question, then we will increase the given number on the coordinate given.
so X= 3+5=8
Y= 5-2=3

If Tammy has 5 credit cards that are all maxed out, a bank could deny her a loan to buy a house based on her __________.
Answer:
access to credit I think
Step-by-step explanation:
I don't know the options but if all her cards are maxed out, she must have horrible credit.
The bank can deny Tammy a loan to buy a house based on her access to credit.
Given that:
Tammy has 5 credit cards.
All of the 5 credit cards are maxed out, which means that all the credit cards have reached the limit of the card and the payment has to be fully paid at the earliest.
The credit scores of one person will be affected when the credit limits are reached and the payment has not been done.
For financial services like loans, credit limits are all important.
So, the bank can deny the service based on the access to credit.
Hence the correct option is A.

Tom received an allowance of $300 for his upcoming trip to Canada. He knows that he will spend $15 each day on food. Which equation represents the amount of extra spending money, m, that Tom will have after d days on his trip?
Answer:
m=15d-300
Step-by-step explanation:
Answer:
300-15d = m
Step-by-step explanation:
Since he spends 15 each day, we dont know how many days, so we put 15d to represent $15 spent each day (d)
We use this formula above ^ and subtract that from 300, which is why it's
300 - 15d
Lastly, we need to find money remaining, so 300 - 15d = m

Suppose the length of a vehicle is drawn to scale. The scale of the
drawing is 1:30. if the length of the drawing of the vehicle on paper is
9.95 inches, how long is the vehicle in feet. (Use only a number for your
answer) *
Answer:
24.88
Step-by-step explanation:
If the scale of the drawing is 1:30, it means that the vehicle drawing is 30 times smaller than the actual vehicle.
Vehicle Length / 30 = Drawing LengthWith the above information in mind, we can calculate the length of the vehicle in inches:
Vehicle Length / 30 = 9.95 inVehicle Length = 30 * 9.95 inVehicle Length = 298.5 inFinally we convert inches to feet(dividing inches by 12):
298.5 / 12 = 24.875 feet— 8х + 3y = 17
8x — 9y = — 19
Answer:
x= 83y−17 and y= 83x+17
