You can tell if a line is parallel because the x (0,0) is straight but with perpendicular its going to change is going to shape its self different

It'll be the opposite reciprocal in front of the X like instead of 3 it will be -1/3 so flip it and change the sign

Which of the following sequences of transformation is used to obtain figure A’B’C’D’ from ABCD?
weeeeeb [17]

Answer:

Most likely (B)

Step-by-step explanation:

Points of ABCD:

A (3,1)

B (3,4)

C (5,5)

D (5,2)

The algebraic rule for reflecting across the y axis:

(x,y) ---> (-x, y)

Points of ABCD after being reflected: (shown by figure 2)

A (-3, 1)

B (-3, 4)

C (-5, 5)

D (-5, 2)

Then, the figure got translated two units to the left, resulting in figure F in the picture, and A’B’C’D’ in the question.

Points of ABCD after being translated by (x-2, y) : (shown by figure F)

A (-5, 1)

B (-5, 4)

C (-7, 5)

D (-7, 2)

This should be the coordinates of A’B’C’D’.

A business purchases a computer system for $5,300. The value of the system decreases at a rate of 12% per year. In how many year
N76 [4]

Answer:

7

Step-by-step explanation:

If a system decreases by 12% it's the same as multiplying it by .12-1 or .88

This means we can create the following equation

computer value=5300(.88)^n

where n is the number of years

We can then plug in the value of the computer and solve for n

2200=5300(.88)^n

Divide by 5300 and get

.415=.88^n

Then put this into log form and get

\frac{log(.415)}{log.88}

Evaluate this into your calculator and get n=6.69 which I would probably just round to 7
