Answer:
he loses 5 dollars
Step-by-step explanation:
5+20=25
25-$20=5
Answer:
y=-4 or y=-6
Step-by-step explanation:
y^2-14y+49=2y^2-4y+73
y^2+10y+24=0
(y+4)(y+6)=0
y=-4 or y=-6
I always start by moving the last term to the other side
To complete the square you take term 'b' , divide it by 2 then square it
= 25
We have to add 25 to what we have and what you do to one side you have to do to the other
Now we factor what is on the left side of the equation
The last step is to move our right side of the equation back over
- which is your answer :)))
We have been given a function . We are asked to find the amplitude, period and phase shift of the function
We can see that our given function is in form , where,
= Amplitude.
Period =
C = Horizontal shift,
D = Vertical shift.
We can see that value of a is 1, therefore, the amplitude of given function would be 1.
We can see that B is equal to 8, so we will get:
Therefore, the period of given function is .
Since the value of C is 1, therefore, horizontal shift is 1.
Since the value of D is 2, therefore, vertical shift would be 2.
Times thoghs by each other and see what u get
