Answer:
- A"(-1, -2)
- B"(6, 0)
- C"(3, 3)
- (x, y) ⇒ (x+1, y+1)
Step-by-step explanation:
Translation vectors add, and the addition is commutative and associative.
__
The first translation adds (-1, 2) to the original coordinates. The second translation adds (2, -1) to the original coordinates. The two translations together add ...
(-1, 2) +(2, -1) = (-1+2, 2-1) = (1, 1)
to the original coordinates.
The single rule representing this translation is ...
(x, y) ⇒ (x +1, y +1)
Then the doubly-translated coordinates are ...
A(-2, -3) ⇒ A"(-1, -2)
B(5, -1) ⇒ B"(6, 0)
C(2, 2) ⇒ C"(3, 3)
There's a 8ft. long board and the carpenter cut off 3 1/2 and 2 1/3.
So first we need to add 3 1/2 and 2 1/3 because the carpenter cut them off the 8ft. long board.
3+2=5 because it's a whole number. 1/2+1/3= 2/6+3/6= 5/6
5 5/6
Now we subtract
8-5 5/6=
7 6/6- 5 5/6= 2 1/6ft.
2 1/6ft. is what remains of the 8ft. board.
Answer:
Ratio is 2:1
Step-by-step explanation:
The bigger triangle is ×2 bigger so ratios can be
2:1 , 4:2, 8:4 , 16:8 and so on
Answer:
780
Step-by-step explanation:
17 is the divisor, while 2635 is the dividend. So that,
= 155
The quotient = 155 = 1 hundreds, 5 tens and 5 units
Also,
2635 - 1700 = 935
Hence, let the unknown value be represented by x. Then;
935 - x
The answer of the subtraction should be equal to the quotient of the division.
935 - x = 155
935 - 155 = x
780 = x
Therefore the unknown value represented by a box is 780.
