42=6x7 then 60=6 x 10 so the least number cover the square should be 6x7x10, that is 420
Answer:
x = -5
y = -1
Step-by-step explanation:
here's the solution :-
- subtracting equation 1 from equation 2 we get,
=》-8x - 4y + 8x - 6y = 44 - 34
=》-10y = 10
=》y = -1
plugging the value of y in equation 2 we get :-
=》-8x - 4y = 44
=》-8x - (4 × -1) = 44
=》-8x + 4 = 44
=》x = 40 ÷ -8
=》x = -5
10x - 7y = -1....multiply by -1 to make that -7y positive
-2x - 7y = -25
------------------
-10x + 7y = 1 (result of multiplying by -1)
-2x - 7y = -25
-----------------add
-12x = - 24
x = 2
-2x - 7y = -25
-2(2) - 7y = -25
-4 - 7y = -25
-7y = - 25 + 4
-7y = - 21
y = 3
solution is : (2,3)

Answer:
- C) (x, y) ⇒ (-x, y)
- D) (x, y) ⇒ (x, y+4)
Step-by-step explanation:
ΔDEF is a reflection and translation of ΔABC.
You know it is a reflection because the corresponding vertices have opposite orientations: CCW vs. CW. You know it is a horizontal reflection because the line EF corresponding to vertical line BC is still vertical.
You know a vertical translation is involved because corresponding vertices are all offset vertically from each other by the same amount (4 units).
