Answer:
Step-by-step explanation:
4. the algebraic representation of the translation is
x+9 and y -4
because for example point (-3, 9) become ( -3+9= 6, 9-4=5)
5.
7 to the left means -7 on the x coordinate and
6 up means +6 on the y coordinate
( x, y ) after translation is ( x-7, y+6)
(12, 3) becomes (12-7= 5, 3+6=9)
(14, 6) becomes (14-7=7, 6+6=12)
(8, 4) becomes(8-7= 1, 4+6=10)
Answer:
6m + 2
Step-by-step explanation:
To simplify the expression you must have to use the distributive property:
(3m + 1)(2)
2 x 3m = 6m
2 x 1 = 2
6m + 2
Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
