Answer:

A(1,1)\to A'(-1,1)

Step-by-step explanation:

The rule for reflecting a given point (x,y) over the y-axis is (x,y)\to(-x,y).

That means we reflect a given point over the y-axis by negating the x-coordinate of the given point.

If one of the options is "negate the x-coordinate of the preimage", then this is the correct option.

If you have: A(1,1)\to A'(-1,1) among the options, then it is the correct answer.

Answer:

(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);

Step-by-step explanation:

formula to find area is L* W = A ; meaning length multiplied by width equals to the area.

21.

using the formula to find area...

l*w=a

(7x+2)(3x-1) would be your answer

btw, don't put the "=a" at the end, since it's an expression :))

22.

since the problem states that it's a square, you can just say either...

(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts

A new car is purchased for 18000 dollars. The value of the car depreciates at 13.5% per year. What will the value of the car be,
leonid [27]

Answer:

The value of car after 14 years is  $ 2,363.04

Step-by-step explanation:

Given as :

The price of new car = N = $ 18,000

The rate of depreciation of the value of the car = R = 13.5 % per year

Let The value of car after 14 years = $ x

The time period = 14 years

<u>Now, According to question</u>

The value of car after n years = initial value of car × (1-\dfrac{\textrm rate}{100})^{\textrm Time}

or, $ x = N × (1-\dfrac{\textrm R}{100})^{\textrm n}

or, $ x = $ 18,000 × (1-\dfrac{\textrm 13.5}{100})^{\textrm 14}

Or, $ x = $ 18,000 × (0.865)^{14}

∴  x = $ 18,000 × 0.13128

I.e x = $ 2,363.04

So, The value of car after 14 years =  x = $ 2,363.04

Hence The value of car after 14 years is  $ 2,363.04  Answer
