Answer:
x = 2
Step-by-step explanation:
Distribute
3 (−4) = 2 (−2+1)
3 − 12 = 2 (-2x +1)
Distrubute again
3x - 12 = -4x + 2
Add twelve to both sides of the equation
Simpfly
3x = -4x + 14
Add 4x to both sides of the equation
simpfly
7x = 14
Divide both sides of the equation by the same term
Simpfly
x = 2

The side lengths of A'A and B'B are 18 and 9 respectively.
What are similar triangles?When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.
Given that, segment A'B' is parallel to segment AB.
Let A'A =x and B'B = y.
Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.
As per the property of similar triangles, it follows:
12/8 = (12 + x)/20
12 + x = (12/8)20
x = 18
And,
6/8 = (6+y)/20
6 + y = (6/8)20
y = 9
Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

Answer:
13
Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169

Help on number two and plz
Answer:
The awnser would be 9 because its under the sum of 10
Answer:
9 (see below)
Step-by-step explanation:
So, for a triangle, if you add any two sides, it will always be greater than the third side.
So if a triangle has sides of 1, 1, and 1:
1 + 1 > 1
1 + 1 > 1
1 + 1 > 1
So this is a triangle.
For a triangle with the sides of 3, 3, and 9:
3 + 9 > 3
9 + 3 > 3
3 + 3 > 9 (this one is not true)
So, these can't be the values of the sides of a triangle.
For your situation, you have a triangle with sides of 4, 6, and x.
We need to find out what x is, so:
4 + 6 > x
4 + x > 6
6 + x > 4
Isolate x to one side and simplify all the inequalities. You will get:
x < 10
x > 2
x > -2
So, -2 < x < 10.
If you plug in your answer choices, it will be 9.

Factor this equation using the Zero product property , What are the x-intercepts?: f(x)=2x^2+5x-3
Answer:
x = 1/2
x = -3
Step-by-step explanation:
[tex]f(x)=2x^2+5x-3[/tex]
Factor
Zero Product Property
X-Intercepts
____________________
To find the x intercepts, we need to first factor our given polynomial. The quickest trick I use to factor is to find two numbers that multiply to c (in this case -3) and the same two numbers that add to b (in this case 5).
The two numbers would be -1 and 3, but along with 2x to help out.
Therefore the binomial for this factor is :
[tex](2x-1)(x+3)[/tex]
Now to solve the x-intercepts, we separate the binomials into an algebraic expressions :
2x - 1 = 0
x + 3 = 0
Isolate for x in both of them :
2x - 1 = 0
Add 1 to both sides :
2x = 1
Divide both sides by 2 :
x = 1/2
x + 3 = 0
Subtract 3 from both sides :
x = -3
Jordan walks 250 m North towards school. He forgets his backpack and walks 250 m South back to his house. He then finds his backpack and walks 900 m North. He gets to school in 9 minutes. What is his velocity in meters per minute
Answer:
10 m / minute
Step-by-step explanation:
Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900
Displacement / time
Displacement = 900
Time = 9 minutes
900 / 9
= 10 m / minute

3х + Зу = -x+5y ordered pair
Answer:
2x-y=0
x=1/2y
Step-by-step explanation:
Answer:
Your solution is (1/2, 1).
Step-by-step explanation:
3х + Зу = -x + 5y
First we want to look at each side of the equation separately.
3х + Зу ⇒ This expression is fully simplified because you cannot add different variables together.
-x + 5y ⇒ This expression is fully simplified because you cannot add different variables together.
3х + Зу = -x + 5y
Now, let's bring the like terms together.
[add x to both sides]
x + 3x + 3y = -x + x + 5y
4x + 3y = 5y
[subtract 3y from both sides]
4x + 3y - 3y = 5y - 3y
4x = 2y
We want to solve for one variable at a time, so let's isolate x.
[divide both sides by 4]
4x/4 = 2y/4
x = 1/2y
Now we have an expression for x. Plug this expression in to your original equation.
3х + Зу = -x + 5y
3(1/2y) + 3y = -(1/2y) + 5y
According to PEMDAS (parentheses/exponents | multiplication/division | addition/subtraction), we should multiply first.
3(1/2y) + 3y = -(1/2y) + 5y
3/2y + 3y = -1/2y + 5y
Now let's add on each side.
9/2y = 9/2
Now we need to isolate y by dividing both sides by 9/2 (or multiplying by its reciprocal 2/9 ← This is often easier to understand when written)
[tex]\frac{2}{9} (\frac{9}{2} y) = \frac{9}{2} (\frac{2}{9} )[/tex]
In this form, we can see that the fractions cancel each other out.
y = 1
Now that we have the value of y, plug it into our equation for x.
x = 1/2y
x = 1/2(1)
Multiply.
x = 1/2
Your solution is (1/2, 1).
You're almost done! Check your answer by plugging in both these values in to your original equation.
3х + Зу = -x + 5y
3(1/2) + 3(1) = -(1/2) + 5(1)
Multiply.
3(1/2) + 3(1) = -(1/2) + 5(1)
3/2 + 3 = -1/2 + 5
Add.
9/2 = 9/2
This equation is true, therefore your answer is correct!
Hope this helps!

When Groundhog Day is
on a weekday,
around15,000 people
attend the events in
Punxsutawney, PA. If two-
thirds take the shuttle bus
to the park for $5 and the
rest pay $25 for parking,
how much money does
the city earn?
====================================================
Work Shown:
2/3 of 15,000 = (2/3)*15000 = 10,000
This means 10,000 people take the shuttle bus to the park. If each person pays $5 to take the bus, then the city earns 5*10,000 = 50,000 dollar through this option.
The rest pay for parking, so 15,000-10,000 = 5,000 people pay for parking. At $25 each, this amounts to 25*5,000 = 125,000 dollars earned through this option.
Overall, the city earns a total of 50,000+125,000 = 175,000 dollars
Side note: this assumes that the remaining 5,000 people all take separate cars and no single car has more than one person. This is very unrealistic as there are likely to be families or carpools of some kind. So in reality, the answer shown above is an upper estimate of the total revenue.
