6x - 3y = 15.....multiply by 4
7x + 4y = 10....multiply by 3
---------------
24x - 12y = 60 (result of multiplying by 4)
21x + 12y = 30 (result of multiplying by 3)
---------------add
45x = 90
x = 90/45
x = 2
6x - 3y = 15
6(2) - 3y = 15
12 - 3y = 15
-3y = 15 - 12
-3y = 3
y = -3/3
y = -1
solution is (2,-1) <==
Well if all angles are suppose to add up to 360 degrees you can the angles to see if the equal up to 360 degrees, 264+96=360.
GCF is Greatest Common Factor and LCM is Least Common Multiple
Answer:
d. y - 3 = f(x).
Step-by-step explanation:
The red graph is the translation of the black one up 3 units.
y = f(x) becomes y = f(x) + 3 or
y - 3 = f(x).
