The value of a graphing calculator is $225. After 2 years, the value of this calculator is $160. Find the value of the calculato

OlgaM077 [116]

To find the value of the calculator after 5 years, you need to find how much the price of the calculator drops each year. From years 0 to 2, it seems that the price of the calculator has dropped by some amount of money x. To find how much the calculator drops each year, first you will need to subtract 160 from 225 (225-160) to get 65. Next, you need to divide 65 by 2 (65/2) to get $32.50.

I believe that in order to find the price after 5 years, you will need to multiply 32.5 by 5 (32.5*5) to get $162.50. Next you would subtract $162.50 from $225 (225.00-162.50) to get $62.50.

So, the price of the calculator after 5 years is $62.50!

I hope this helps!

Explain what their first step would be if they wanted to eliminate the y variable from the equations.

Vinvika [58]

Answer:

r1 +4×r3 ⇒ r1
r2 -3×r3 ⇒ r2

Step-by-step explanation:

We note that the coefficient of y in equation (iii) is 1, so it is convenient to use that equation to eliminate y from the others.

<em>To eliminate the y-variable from equation (i), four times equation (iii) can be added to equation (i).</em>

<em>To eliminate the y-variable from equation (ii), three times equation (iii) can be subtracted from equation (i).</em>

_____

The result of these operations would be ...

$10x +6z = 28\quad\text{(iv)}\\\\-7x-9z=2\quad\text{(v)}$

Hi there,
To compare we can look at the amount of (ounces)
A: 12 B:24
so as it appears B wins this part
Now price
A: $ 4.39 B:$2.79
A is relatively expensive than B
B is cheaper with more ounces
A is less ounces and relatively expensive
which one would you buy?

You invested $10,000 into two accounts: one that has a simple 3% interest, the other with 2.5% interest. If your total interest

artcher [175]

Answer:

3300 was on 3% and 6700 on 2,5%

Step-by-step explanation:

We can say that 'a' represents the price that will go on 3% interest and 'b' 2,5% interest.

Therefore;

a + b = 10 000

And

0,03a + 0,025b = 283.5 (0,03 means 3% etc)

You can move 'b' to the other side to leave 'a' on the LHS

0,03a = 283.5 - 0,025b - - > (divide both sides by 0,03)

a=9450 - 0,8333b

Substitute this equation as 'a' in the first equation to get:

9450 - 0,8333b + b = 10 000 (move 9450 to the RHS to leave values with b on the LHS)

-0,8333b + b = 10 000 - 9450

0,1666b = 550 (divide both sides by 0,1666)

b = 3,300

Therefore 'a' will be :

a= 10 000 - 3 300

a = 6700

I hope this helps.
