Answer:
f(9) = 8
Step-by-step explanation:
Step 1: Define
f(x) = x - 1
f(9) is x = 9
Step 2: Substitute and Evaluate
f(9) = 9 - 1
f(9) = 8
Answer:
Step-by-step explanation:
Simplify to:
Multiply both sides by 7
2(x-2)=28x
Divide both sides by 2
x-2=14x
Subtract x from both sides
2=14x-x
Simplify 14x-x to 13x
2=13x
Divide both sides by 13
Answer:
The width of rectangle is 8 units.
Step-by-step explanation:
Given,
Area of rectangle = 40 units
Width = w
Length = w-3
Area = Length * Width
Factorizing the equation
Either,
w-8=0 => w=8
Or,
w+5=0 =>w= -5
As width cannot be negative, therefore
Width of rectangle = 8 units
The width of rectangle is 8 units.
