Answer:
(4, –1.5)
Step-by-step explanation:
Answer:
Final answer is x=90,
Step-by-step explanation:
Given equations are:
-x-4y=37 ...(i)
-2x-4y=-53 ...(ii)
multiply (ii) by -1
2x+4y=53 ...(iii)
Add (i) and (iii)
x=90
plug value of x=90 into (i)
-x-4y=37
-90-4y=37
-4y=37+90
-4y=127
Hence final answer is x=90,
Answer:
X=90, y =-127/4
Step-by-step explanation:
Subtract the second equation from the first and you get X+ 0y= 90. Replace x=90 in either equation and you get y= -127/4.
Hello!
An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object ?
We have the following data:
KE (Kinetic Energy) = 480 J
m (mass) = ? (in Kg)
v (speed) = 8 m/s
Formula to calculate kinetic energy:
Solving:
Answer:
b) 15 kg

Answer:
L(4,-3) -> L'(4,9)
M(4,3) -> M'(4,3)
N(-4,3) -> N'(-4,3)
K(-4,-3) -> K'(-4,9)
Step-by-step explanation:
Reflection of an object means to flip that object on a line called the axis of reflection or line of reflection or mirror line.
Line of reflection here is y = 3
So, after a reflection over the line y = 3
Co ordinates
L' = (4,9)
M' = (4,3)
N' = (-4,3)
K' = (-4,9)
A reflection over the line y=3 changes the y-coordinate of a point to 2*3 minus its original y-coordinate, keeping the x-coordinate the same.
To find the coordinates of the vertices after a reflection over the line y=3, one should understand that a reflection over a horizontal line, such as y=3, changes the y-coordinate of each point while keeping the x-coordinate the same. For instance, if you have a point (a, b), after reflecting over the line y=3, the new point would be (a, 2*3-b). This is because the difference between the y-coordinate of the point and the line of reflection (3 in this case) would be the same before and after reflection, but with a different sign.
For example, if you have a vertex at (2, 5), to find its new position after reflection, you would keep the x-coordinate (2) the same, and calculate the new y-coordinate as (2*3 - 5) = 1. So, the reflected vertex would be at (2, 1). Apply this same method to all vertices to find their new positions after reflection.
