Blizzard [7]3 years ago
6 0

The formula of a midpoint SR:

M\left(\dfrac{x_S+x_R}{2},\ \dfrac{y_S+y_R}{2}\right)

We have

S(4, 1) and M(7, -5)

Substitute:

\dfrac{4+x_R}{2}=7\qquad|\cdot2\\\\4+x_R=14\qquad|-4\\\\x_R=10\\\\\dfrac{1+y_R}{2}=-5\qquad|\cdot2\\\\1+y_R=-10\qquad|-1\\\\y_R=-11

<h3>Answer: R(10, -11)</h3>

A client's inventory is recorded at $600,000 and is comprised of 1,000 items. The auditors examined a sample of items with a rec
KonstantinChe [14]

Based on the calculation done below, the estimated audited value for inventory is $540,000.

<h3>How is the estimated audited value for inventory calculated?</h3>

This can be calculated using the following formula:

E = (T / S) * A ……………………… (1)

E = Estimated audited value for inventory = ?

T = Total value of inventory recorded by client = $600,000

S = Value of inventory sampled by the auditor as recorded by the client = $100,000

A = Audited value of the inventory sampled = $90,000

Substituting the values into equation (1), we have:

E = ($600,000 / $100,000) * $90,000

E = 6 * $90,000

E = $540,000

Therefore, the estimated audited value for inventory is $540,000.

Answer:

Red grapefruit costs more per pound.

Step-by-step explanation:

Red grapefruit

y =2x

This is in the form y= mx+b  where m is the slope and b is the y intercept

The cost per pound is the slope, which is 2

The cost per pound is $2


Pink grapefruit

We need to find the slope

We have 2 points (0,0) and  (4,4)

m = (y2-y1)/(x2-x1)

   = (4-0)/(4-0)

   =4/4

  = 1

The slope is 1

The cost per pound is $1

What is the equation of the line that passes through (-1, 5) and (3, -7)?
enyata [817]

Answer:

3x + y = 2

Step-by-step explanation:

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

y - 5 = \dfrac{-7 - 5}{3 - (-1)}(x - (-1))

y - 5 = \dfrac{-12}{4}(x + 1)

y - 5 = -3(x + 1)

y - 5 = -3x - 3

3x + y = 2
