Answer:
Below
Step-by-step explanation:
Let y be the missing number inside the box. The equation is:
●y( x-3)+2x= -(x-5)+4
● y (x-3) +2x = -x+5+4
● y (x-3) +2x = -x+9
● y (x-3) +2x+x = 9
●y(x-3)+3x =9
● yx-3y+3x= 9
●yx-3y+3x-9=0
●y(x-3) +3(x-3) =0
● (x-3)(y+3) = 0
●x-3=0 or y+3=0
●x=3 or y = -3
●x=3 or -y = 3
Add them together
● x-y = 6
●x=6+y
● y =6-x
So the number we should put in the box is 6-x
Step-by-step explanation:
The function is given by
It is an absolute value function which has a v- shaped graph.
The vertex form of an absolute function is given by y = a|x-h| +k, where (h,k) is the vertex.
Comparing the given equation with this, we have
h = 12
k = -2
Hence, the vertex would be (12,-2).
Now, the range of the function is the set of y values for which the function is defined.
This function has vertex of (12,-2). hence, it would not take any values which are less than -2. Please see the attached graph.
Hence, the range would be the all y values greater than or equal to -2.
Hence, the range is given by
If the rate at which they are giving the DVDs is the same then it is 4/65 or 16.25% or 0.1625.
Now just multiply 455 by the rate (4/65 or 16.25% or 0.1625) to find how many DVDs were given.
455 × (4/65) = 28
28 DVDs were given away
hope it helps :)
