Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.
So based on your question where GD is 1=4 4/3 what could be the value of GH. So first of that you need to consider that point D. is the midpoint of GH and GD = DH right ? So with that information the answer would be 9 1/3
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
