No, an object can't be reflected over a line without changing its position.
What is Reflection?A Reflection is a transformation representing a flip of a figure.
Given that an object can be Reflected over a line without moving its position,
There are certain rules for reflection of figures,
(x, y) → (x, -y)(x, y) → (-x, y)(x, y) → (y, x)(x, y) → (-y, -x)Using these rules, a point is reflected, so it's not possible for an object to be reflected without changing position.
Hence, an object can't be reflected over a line without changing its position.

What is the equation in point-slope for the linear function whose graph contains points (1, -2) and (-3, 6)?
A. y - 6 = 2(x + 3)
B. y - 6 = -2(x + 3)
C. y - 2 = -2(x - 1)
Answer:y+2 = 2(x-1)
Step-by-step explanation:
First we find the slope
(1,-2) (-3,6)
rise/run
change of y/change of x
8/-4
-2
The slope is -2
point slope form is y-y1 = m(x-x1)
m is the slope, y1 is y coordinate of a point and x1 is x coordinate of same point as the y1 point.
lets use (1,-2)
y-(-2) = 2(x-1)
point slope form
y+2 = 2x-2
y = 2x-4
slope intercept form
if a wire of length 2 meters costs $10. find the cost of a wire of length 35cm $1.75
Answer:
$1.75Step-by-step explanation:
if a wire of length 2 meters costs $10. find the cost of a wire of length 35cm $1.75
2m = 200 cm
200 : 10 = 35 : x
x = 10 * 35 : 200
x = 1.75

I need help with this one to / surface area :)
Answer:
389.9 to 1 decimal place
If you need another explanation comment on this one
Step-by-step explanation:
the surface area (base area plus side wall) of a cone is, when we have the radius and the length of the slanted side wall :
SA = pi×r×(r + l)
in our case here
r = half of the diameter = 12/2 = 6 m
l = 13.4 m
so, we have
SA = pi×6×(6 + 13.4) = pi×6×19.4 = 365.6813849... m²

Which statement is true about the prime polynomial 2x2 + 3x + 3?
It cannot be modeled with a rectangle.
It can be modeled with a square.
It cannot be modeled with all positive tiles.
It can only be modeled with an odd number of tiles.
Answer:
it cannot be modeled with a rectangle
Step-by-step explanation:
let's eliminate the wrong answers first
1. it cannot be modeled with all positive tiles --- this incorrect because it is all positive, so it CAN be modeled with all positive tiles
2. it can only be modeled with an odd number of tiles -- not true, because 2x^2 is even number of tiles
3. it can be modeled with a square -- to be modeled as a square, the polynomial have to be factored into square ie (x+2)², but cann't be factored as square, so again not true
therefore, first one is the answer. because you cannot factor the polynomial as such (x+2)(x+3), so it cannot be modeled with a rectangle.
Answer:
A: It cannot be modeled with a rectangle.

The ratio of the number of girls to the number of boys is 3:5 . if the number of boys os 12 more than the number of girls ,calculate the total number of students in the class.
Answer:
48 students in the class
Step-by-step explanation:
The ratio of girls to boys is 3 : 5 = 3x : 5x ( x is a multiplier ) , then
5x = 3x + 12 ( 12 more boys than girls )
Subtract 3x from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
number of girls = 3x = 3 × 6 = 18
number of boys = 5x = 5 × 6 = 30
total students in class = 18 + 30 = 48

30/x = 54/81 what value does x have to be to make it true
Answer:
x=45
Step-by-step explanation:
30/x = 54/81
30 = 54/81(x)
x = 30 ÷ 54/81
x=45
Answer:
x = 45
Step-by-step explanation:
30/x = 54/81
~Cross multiply
30 * 81 = 54 * x
~Simplify
2430 = 54x
~Divide 54 to both sides
45 = x

Answer:
I think u mean to just multiply 300 * 47 would equal 14,100
300
x 47
7*0 = 0 7*3=21 so 2,100
40*0 = 0 since 40 has a 4 you can take 4*3 and put a 0 on the end 4*3= 12 so 40*3= 120 so with so with the bonus 0's it would be 12,000
12,000
+ 2,100
14,100 so that means

Answer:
Step-by-step explanation:
4(3x+2y)+6(−2x−5y)
Use the distributive property to multiply −4 by 3x+2y.
−12x−8y+6(−2x−5y)
Use the distributive property to multiply 6 by −2x−5y.
−12x−8y−12x−30y
Combine −12x and −12x to get −24x
−24x−8y−30y
Combine −8y and −30y to get −38y.
and you get −24x−38y

A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began.
The equation that models this situation is z = 7.9y + 12.
A linear equation is a function that has a single variable raised to the power of 1. An example is x = 4y + 2.
Where:
2 is the constantx = dependent variable y = independent variableFrom the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.
