Ray industries bought a touchscreen monitor for $1200 it is expected to depreciate at a rate of 25% per year what was the value
max2010maxim [7]

So for this problem, we will be using the exponential equation format, which is y = ab^x. The a variable is the initial value, and the b variable is the growth/decay.

Since our touchscreen starts off at a value of 1200, that will be our a variable.

Since the touchscreen is decaying in value by 25%, subtract 0.25 (25% in decimal form) from 1 to get 0.75. 0.75 is going to be your b variable.

In this case, time is our independent variable. Since we want to know the value 3 years from now, 3 is the x variable.

Using our info above, we can solve for y, which is the cost after x years.

y=1200*0.75^3\\y=506

In context, after 3 years the touchscreen will only be worth $506.

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?
Sophie [7]
Here are the numbers
4.3 , 5.5 , 6\frac{1}{6} , \frac{15}{4} , 4\frac{3}{8}
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
6\frac{1}{6}<em />⇔6.1666---
\frac{15}{4}⇔3.75
4 \frac{3}{8}⇔4.375
Now to arrange them from least to the greatest
\frac{15}{4} , 4.3 , 4 \frac{3}{8} , 5.5 , 6\frac{1}{6}

what is the equation of the line that is parallel to the given line and passes through the point (2, 3) ? a. x + 2y = 4 b. x + 2
aleksandr82 [10.1K]

Answer:

see explanations

Step-by-step explanation:

The given blue line has a slope of m = -1/2.

The line parallel to the given line passing through point (x0,y0)=(2,3) is given by the point-slope form:

(y-y0)=m(x-x0)

substitute values

(y-3) = (-1/2)(x-2)

Expand and transpose

y = (-1/2)x + 1 + 3

y = (-1/2)x + 4  ....................(1)

We choose the second equation b. x+2y=8 and convert to slope-intercept form:

2y=-x+8

y = (-1/2)x + 4, which is exactly equation (1)

So

b. x+2y=8 is the correct answer.

- x - x + 11 - 2x = 83<br>please show step by step!!​
m_a_m_a [10]

Answer:

x=-18

Step-by-step explanation:

<u>Given</u>

<u />-x-x+11-2x=83

<u>Step 1: Combine Like Terms on LHS</u>

<u />-x-x+11-2x=83\\-2x+11-2x=83\\-4x+11=83

<u>Step 2: Subtract 11 on both sides</u>

<u />-4x+11=83\\-4x+11-11=83-11\\-4x=72

<u>Step 3: Divide both sides by -4 to isolate the x-variable</u>

<u />-4x=72\\\\\frac{-4x}{-4}=\frac{72}{-4}\\ \\ x=-18

<u>Final Answer</u>

<u />x=-18
