When f(x) = 0.5|x is graphed on a regular coordinate grid, the graph forms
PtichkaEL [24]

Answer:

A. Right angle  -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.

When no more than 110 units are produced, the cost of producing y units is given by C(x).
Maslowich

Producing 73.8 units gives the lowest possible average cost.

The average cost (AC) is the ratio of the total cost to the number of units produced. It is given by:

AC = C(x) / x

AC = (0.2x³ – 24x² + 1514x +30064) / x

AC = 0.2x² - 24x + 1514 + 30064/x

The lowest possible average cost is at AC' = 0. Hence differentiating the average cost, gives:

AC' = 0.4x - 24 - 30064/x²

0.4x - 24 - 30064/x² = 0

0.4x³ - 24x² - 30064 = 0

Solving the cubic polynomial gives:

x = 73.8 units

Therefore the lowest possible average cost is when 73.8 units are produced.

4x+5y=-13;5x-2y=-8 solve elimination method <br> Step by step
goldfiish [28.3K]
4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)

5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)

equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2

substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1

The values of x and y are -2 and -1 respectively.

A sporting goods store charges $27 for 3 basketballs and $90 for 5 boxes of sneakers. A coach orders 40 basketballs and 7 boxes
ValentinkaMS [17]

Answer:

<h3> Let's start with the total money needed for basketballs</h3>

The total money the coach will need for 40 basketballs will be 40 times price of one basketball.

Thus we need to find the price of one basketball.

$27 for 3 basketballs

Thus for one basketball, \frac{27}{3} Which gives us,

'9'.

So for 40 basketballs 40 * $9

Which gives us $360.

<h3>Now let's find the total money needed for sneakers.</h3><h3></h3>

The total money needed for sneakers is 7 times the cost of one sneaker.

So, we need to find the cost of 1 sneaker

which is \frac{90}{5}  which gives us,

$18.

Thus total amount of money  needed for sneakers is 9 * $18 which gives us

$162

So total amount the coach has to pay is $360+$162 <em>(total cost of basketballs + total cost of sneakers)</em>

=$552

Therefore, total amount the coach has to pay is $552
