Answer:approximately 65.6
Step-by-step explanation:
I’m not really sure but I would have to guess 4.5 because all of the other numbers don’t have decimals
Answer:
b= -1
Step-by-step explanation:
48 =. 56 +8b
-56 -56
---------------------------------
-8 = 8b
Divide 8 on both sides
-1=b
I think it would a minimum because its positive. and the vertex would be (-.77,4.55) the minimum is 4.55
Your answer would be x=-10.5
First distribute -2/3 to 3x and -9
-2x+6=15
Then subtract 6 from both sides
-2x=9
Divide both sides by -2
x=-4.5
