Answer:
C
Step-by-step explanation:
If each input value leads to only one output value, classify the relationship as a function.
14 x 12 = 168
168 divded by 2.90 = 57.9
Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
4/6=2/3 (divide both numerator and denominator by 2 (gcd)).
Hope this helps.
