The solution of the given inequality 8(u + 8) ≥ 8u+8 is true for all u.
We have given inequality 8(u + 8) ≥ 8u+8
What is inequality?
A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
Expand 8(u + 8)
Subtract 64 from both sides
Simplify given term
Subtract 8u from both sides
Simplify it
Therefore the solution is true for all u.

Answer:
Step-by-step explanation:
step 1
Find the equation of the first inequality
Find the equation of the first solid line
we have the ordered pairs
(0,-2) and (2,0)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
The equation in slope intercept form is equal to
we have
---> the y-intercept is given
substitute
Remember that
Everything to the left of the solid line is shaded
so
The inequality is
step 2
Find the equation of the second inequality
Find the equation of the second dashed line
we have the ordered pairs
(0,2) and (4,0)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
The equation in slope intercept form is equal to
we have
---> the y-intercept is given
substitute
Remember that
Everything below and to the left of the line is shaded
so
The inequality is
Rewrite
Multiply by 2 both sides
therefore
The system of inequalities is
