Answer:
13x
Step-by-step explanation:
You add them all up since they're like terms and all have x
1. so just subsitute numbers if we subsitute 5 for x then we get 0 if it's height is 6 then the time will be 16
2. so you want to factor the equation and get f(x)=x^2-4x-5=(x-5)(x+1) then set this equation = to 0 so (x-5)(x+1)=0
x-5 or x+1 must equal 0 so
x-5=0
x=5
x+1=0
x=-1
discard this because you cannot yield a negative ammount
so when the bank yields 5 in a day, the income is 0
Answer:
2,1
Step-by-step explanation:
Im sure it's -3 Because well thats what i got
Since the circle is white, not filled in, that means 2 is not included. So, the sign must be either < or >. Therefore, answers B and D are wrong.
Since the arrow is going to the left side that means x must be LESS than 2, so the sign must be <.
Therefore, answer is A.
