x- the number

9x - 4

Four less (-4) than nine times number (9x)

x/4 + 9

Nine more (+9) than one-fourth of number (1/4 x = x/4)

4 - 9x

Four (4) decreased (-) by the product of a number and nine

4x - 9

Nine less (-9) than a four times number (4x)

x/9 + 4

The sum (+) of one-nineth a number (1/9 x = x/9) and four (4)

Maksim231197 [3]

Answer:

v = - 3

Step-by-step explanation:

Given

v = u + at ← substitute u = 2, a = - 5, t = 1 into the expression

v = 2 + (- 5 × 1) = 2 + (- 5) = 2 - 5 = - 3

A painter is placing a ladder to reach the third story window, which is 12 feet above the ground and makes an angle of 80 degree
mash [69]
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅

in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft  (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft

the answer is
2.12 ft

Digital music distribution provides an opportunity for everyone to get their music heard. In order to get on a service like iTun
Fiesta28 [93]

Based on the charge to the artist and the amount the streaming services pay, the following are true:

  1. -50.
  2. 5.
  3. y = 5x - 50
  4. .
  5. 10,000 streams.
  6. 190,010,000 streams

<h3>What model can be derived for the streaming data?</h3>

The y-intercept would be the amount that the artist has before they start making any money. In this case that amount is -$50 because they will owe the distributor.

The slope is the change per unit which is $5.00 here.

The formula is therefore:

y = mx + b

y = Slope × x + b

y = 5 × x + (-50)

y = 5x - 50

The number of streams to pay off the distributor is when the profit is $0:

0 = 5x - 50

50 = 5x

x = 10 units

Number of streams:

= 10 units x 1,000

= 10,000 streams

To make a profit of $950,000, the units are:

950,000 = 5x - 50

5x = 950,000 + 50

x = (950,000 + 50) / 5

= 190,010 units

Number of streams is:

= 190,010 x 1,000

= 190,010,000 streams
