Answer: 1 and 2 x is 75

Y=110

Step-by-step explanation:

180-30=150/2=75

X=75

75+20=95

75+10=85

95+85=180

110+(110-40)=180

110+70=180

Write an equation for the line that passes through the points (0, -6) and (-3, 0).

Dmitry [639]

Answer:

$\displaystyle y = -2x -6$

Step-by-step explanation:

x-intercept → Plug in 0 for <em>y</em><em> </em>to get −3 for <em>x</em>

y-intercept → When <em>x</em><em> </em>is set equal to 0 [(0, −6)]

Read the problem to choose the correct method, then solve. A farmer buys a tractor for $50,000. If the tractor depreciates 10% p

OlgaM077 [116]

Answer:

The correct option is, Exponential Decay, $23,914.85.

Step-by-step explanation:

A farmer buys a tractor for $50,000.

It is provided that the the tractor depreciates 10% per year.

The exponential function for decay is:

$y=a\cdot (1-r\%)^{t}$

Here,

a = initial value

r = decay rate

t = time

Compute the value of the tractor in 7 years as follows:

$y=a\cdot (1-r\%)^{t}$

$=50000\times (1-0.10)^{7}\\\\=50000\times 0.4782969\\\\=23914.845\\\\\approx 23914.85$

Thus, the correct option is, Exponential Decay, $23,914.85.
