Step-by-step explanation:
it means that x has now to be the result variable, and y the input variable.
so,
y = 3x - 5
y + 5 = 3x
x = (y + 5)/3
and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get
y = (x + 5)/3
as the inverse function
Answer:
|x − 3| = 2
Step-by-step explanation:
The difference between his maximum time and his average time is +2 hours.
x − 3 = 2
The difference between his minimum time and his average time is -2 hours.
x − 3 = -2
Using absolute values:
|x − 3| = 2
Answer:
Step-by-step explanation:
Given
Required
Shift 
down and 
right
<u>Shift 3 units down</u>
The rule is: (x,y)=> (x,y-a)
Where a is the number of units shifted down
In this case: 
So, we have:
== > 
<u>Shift 2 units right</u>
The rule is: (x,y)=>(x-b,y)
Where b is the number of units shifted right
In this case: 
So, we have:
==> 
Open bracket:
Hence, the new equation after the transformation is:
I only know the part 3*n-8≤ -7
Answer:
∠ WXY = 20°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ XYZ is an exterior angle of the triangle, thus
10x - 5 = 3x + 17 + 3x + 2
10x - 5 = 6x + 19 ( subtract 6x from both sides )
4x - 5 = 19 ( add 5 to both sides )
4x = 24 ( divide both sides by 4 )
x = 6
Thus
∠ WXY = 3x + 2 = 3(6) + 2 = 18 + 2 = 20°
