3 triangles.
If you take 3 toothpicks you create the first triangle. You put the last toothpick down the middle, you get 2 more
80 because the both lines intersect at this point.
Answer:
To get the function g, shift f by 1 unit.
Step-by-step explanation:
Given

Required
How do f(x) translates to g(x)
In terms of f(x), g(x) can be represented as:

Where

and

<em>This implies that f(x) is vertically shifted 1 unit up to get g(x)</em>
Answer:
45
Step-by-step explanation:
Let the unit place be ‘x'
Tenth place be y
The number is 10y+x
x+y = 9 (according to the condition) (1)
Digits are interchanged Unit place' y ‘& tenth place ‘ x'
New no is 10x +y
This is 9 more than the original number
10x+ y = 10y+x +9
10x-x+y-10y = 9
9x-9y= 9
x-y = 1 (dividing by 9) (2)
Adding the two equations
2x = 10
x= 5
Substituting the value of x in first equation
y = 4
The number is 45, the original number is 54 this is 9 more of the new number.
