Answer:
Everyone in my household has a computer either for school or work. The youngest needs a computer so she can stay busy and not bother me at all.
We all have different reasons to have one so we all need one.
The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
Answer:
36
Step-by-step explanation: thats what i got
Equilateral means equal sides, so B, sides are congruent.
Answer:
(6, -4)
Step-by-step explanation:
To solve a linear system of equations <u>graphically</u>, graph the given equations and locate where the two lines intersect. The point of intersection is the <u>solution</u> to a system of linear equations.
Given linear system of equations:
Rewrite the second equation to make y the subject:
To graph a linear equation, find two points on the line by substituting two values of x into the equation. Plot the points and draw a straight line through them.
<u>Equation 1</u>
<u>Equation 2</u>
From inspection of the graph (see attached), the point of intersection is (6, -4).
