Answer:
-5,5
Step-by-step explanation:
(2x+5)( 2x-5) x-5=0 x+5=0 I think that's what you do not sure
Answer:
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Step-by-step explanation:
Given that:
Cost of each lunch = $2.50
Cost of monthly lunch pass = $40.00
Number of lunches = x
For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore
Cost of lunch * Number of lunches > Cost of monthly lunch pass
2.50x > 40.00
Hence,
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Answer:
90 engines must be made to minimize the unit cost.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point 
In which
Where
If a>0, the minimum value of the function will happen for 
C(x)=x²-180x+20,482
This means that 
How many engines must be made to minimize the unit cost?
x value of the vertex. So
90 engines must be made to minimize the unit cost.
Standard Form is Ax + By = C
y=2x+5
-2x+y= -2x+2x +5
-2x + y = 5
Answer -2x + y = 5
“d”
you know b cannot work because the x is raised to the x^2 which would be a diff graph
a does not work because -x^3 the graph would be flipped
c is incorrect because the five is in the negative region; not positive
