Answer: True

In math terms, an "image" is the result after a transformation has been applied. One or more transformations can happen here. The original figure is called the "preimage" or "before image" so to speak.

So we go from "preimage" to "image"

preimage ---> image

A maps to A'

B maps to B'

C maps to C'

D maps to D'

15. Tim buys a new computer for his office for $1200. For tax purposes, he declares a linear depreciation (loss of value) of $20

Leokris [45]

Answer:

Slope is -200 and y-intercept is at (0, 1200)

The linear equation is: $y=-200x+1200$

The value of the computer after 4.5 years will be $300.

Step-by-step explanation:

Value of the new computer is $1200

For tax purposes, the linear depreciation (loss of value) is $200 per year.

So after $x$ years, total loss of value will be: $\$200x$

If $y$ is the declared value of the computer after $x$ years, then the linear equation will be.......

$y=1200-200x\\ \\ \Rightarrow y=-200x+1200$

If we compare the above equation with slope-intercept form $(y=mx+b)$ , then we will get: $m=-200$ and $b=1200$

So, the slope of the line will be -200 and y-intercept will be at (0, 1200)

After 4.5 years means $x=4.5$

So when $x=4.5$ , $y=-200(4.5)+1200=-900+1200=300$

Thus, the value of the computer after 4.5 years will be $300.

A diver is 25 feet below see level. After he swims up 15 feet toward surface. What is elevation.

Fiesta28 [93]

Answer:

-10 ft

Step-by-step explanation:

I represent "below sea level" as negative numbers, so 25 ft below sea level would be a -25 ft. Since the diver swims up, or increases by 15 ft, I'd add that.

-25 + 15 = - 10

I hope this helped!
