Describe the graph of y = 3x2 and compare it with the graph of y=x^2.
Answer:
y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.

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

s y=x+7
y = 6x + 2
Solution:
How do you solve this
Step-by-step explanation:
y=x+7........eqni
y=6x+2.....eqnii
putting the value of x in eqnii
y=6x+2
or, x+7=6x+2
or, 7-2=6x-x
or 5= 5x
hence,x=1
sbstutuung the value of x in eqni,
y= x+7
=1+7
=8
hence the value of y is 8

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.
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.

Answer:
The Area of the given figure is 6 inch²
Step-by-step explanation:
For a given Trapezoid
side a = 1 ½ = 1.5 inch
side b = 2½ = 2.5 inch
height (h) = 3 inch
Now, Area of Trapezoid
Formula:A = ½ (a + b) × h
A = ½ (1.5 + 2.5) × 3 inch
A = ½ × 4 × 3 inch
A = 2 × 3 inch
A = 6 inch²
Thus, The Area of the given figure is 6 inch²

−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)

Jill and Gary share £63 in the ratio 2:5
Work out how much each person gets.
Answer:
Jill gets €18 Gary gets €45.
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.
