The answer is A because the negative on the outside if the parentheses cancels out the negative on the inside of the parentheses making it a positive and there is no other point given so it would be 2 units to the right if 0
Answer:
Step-by-step explanation:
t(-7)= 3(-7)= -21
s(-21)= 2-(-21)= 2 + 21= 23
Answer:
Parte1 :
∡B= 180 - (42 + 83)= 55°
Parte2 :
Using the law of sines :
⇔
⇔ a= 142.95
Parte3 :
Using the same law :
or
⇔ c= 212.04
6 is d, 7 is b, 8 is c, 9 is c
5x + 4y = 24
Substitute y for 1
5x + 4 = 24
5x =20
x = 4
