Answer:
3. (3,-4)
Step-by-step explanation:
Answer:
it has infinitely many solutions
All of the angles added together MUST equal 180 degrees, so take 180 and subtract 84 from it.
Therefore, the third angle is a 96 degree angle.
Answer (4):
a=ub/k because
u=ak/b (starting equation)
ub=ak (multiply b to both sides)
a=ub/k (divide both sides by k)
Answer (6)
x=g+c-y because
g=x-c+y (starting equation)
x+y=g+c (add c to both sides)
x=g+c-y (subtract y from both sides)
2^3 * 2^-5 = 2^(3 + (-5) = 2^(3 - 5) = 2^-2
