Streets in the city can be represented by the equations in the given table. Use the equations to find the type of quadrilateral that the streets form. Justify your answer.
Answer:
It is a rhombus.
Step-by-step explanation:
We have the four equations:
3x - y = -4
3y - x = 4
3y = x + 12
y = 3*x - 4
First, we need to write all of them in slope-intercept form, so they are easier to read.
We get:
y = 3*x+ 4
y = (1/3)*x + 4/3
y = (1/3)*x + 12/3
y = 3*x - 4
First, we can see that:
y = 3*x+ 4 and y = 3*x - 4
are parallel lines, because they have the same slope.
y = (1/3)*x + 4/3 and y = (1/3)*x + 12/3 also are parallel lines, because they have the same slope.
Then this is a parallelogram.
Now, here we have two slopes, 3 and 1/3.
Remember that for a line y = a*x + b
A perpendicular line would be written as:
y = -(1/a)*x + c
From this we can see that there are no perpendicular lines in our set of lines.
Then this can not be a square nor a rectangle.
It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.
Then this can only be a rhombus.
Below you can see the graph of the four lines to see which quadrilateral they form.
What is the number of sides of a regular polygon if each interior angle measures 160°?
Answer:
18
Step-by-step explanation:
180-160 = 20 which equals the exterior angle
the sum of exterior angles is 360 so 360/20 = the number of sides as there is an exterior angle for every side
360/20 = 18

−5x + y = −2 −3x + 6y = −12 solved by substitution please work so i can understand
Answer:
x=0 and y= -2
Step-by-step explanation:
−5x+y=−2for y:
−5x+y=−2
−5x+y+5x=−2+5x(Add 5x to both sides)
y=5x−2
5x−2foryin−3x+6y=−12:
−3x+6y=−12
−3x+6(5x−2)=−12
27x−12=−12(Simplify both sides of the equation)
27x−12+12=−12+12(Add 12 to both sides)
27x=0
x=0
Substitute0 for X in y=5x−2:
y=5x−2
y=(5)(0)−2
y=−2(Simplify both sides of the equation)
7x -4 + x = 12.

Which is the better buy? How do you know?
A. 7 ounces of tomato sauce for $2.10
B. 28 ounces of tomato sauce for $5.60
Hello, 928747! I can help you.
So we are trying to find which has a better deal. We can do this by comparing them.
If 7 ounces is $2.10 then we need to turn that into 28 ounces.
Using common multiplication, we know that 7 x 4 = 28.
So we would do the same thing to the price.
2.10 x 4 = 8.4
So, A is $8.40 for 28 ounces.
B is $5.60 for 28 ounces.
Therefore, B has the better deal.

Compare/contrast linear functions and exponential functions.
I need at least 3 to 4 paragraphs
Please Help!
Answer:
Linear functions is just basically straight lines while exponential functions also just curved lines. You can actually also find them by just the change in the y. If the same number is just being added to y, then most likely the function has a constant change and is also linear. Exponential functions will most likely be in the way(form) of the equation y = (1 + r) x. HOPE THIS HELPS!

How does the value of the digit 2 in the number 32,000 compare with the value of the digit 2 in the number 26,000?
Answer: See explanation
Step-by-step explanation:
We should note that the value of the digit 2 in the number 32,000 is 2 thousand. The value of the digit 2 in the number 26,000 is 20 thousand = 20,000.
We can simply say that the value of the digit 2 in 26000 is ten times the value of the digit 2 in 32000.

The total cost of purchasing a leotard, including tax,
was $19.61. Find the cost of the leotard before sales
tax.
Answer:
$18.43
Step-by-step explanation:
19.61 decrease 6% =
19.61 × (1 - 6%) = 19.61 × (1 - 0.06) = 18.4334
The cost of the leotard before sales tax is $18.5
What is the formula to calculate sale tax ?The sales tax is calculated by multiplying the total sales or selling price by the rate of sales tax.
Amount of sales tax = rate of sales tax × Total sales
Rate of sales tax = percent of sales tax / 100
Let the cost of leotard before tax be x
Given that sales tax of 6% is applied over x
The the amount of sales tax =( 6/100) ×x = 3x / 50
The total cost after applying sales = x + (3x/50) = 53x/50
Given that the total cost of purchasing a leotard including tax = $19.61
⇒ 53x/50 = 19.61
⇒53x = 19.61×50
⇒ x = 980.5/53 = 18.5
Therefore, the cost of the leotard before sales tax is $18.5

Step-by-step explanation:
First you add the two numbers of the ratio together. 2+5=7. Then you divide the constant, 63, by the total of the ratio, 7. 63/7=9. Then you multiply each number of the ratio by the quotient. 2 x 9= 18. 5 x 9= 45.
