Please help 5 = (a - 12/15

1 answer:

3 0

Solve by simplifying both sides of the equation, then isolating the variable.

Exact Form: a = 29/5

Decimal Form: a = 5.8

Mixed-Number Form: a = 5 4/5

Hope this helps!

Have a great day!

Graph y=-6(3)^x please do the table and the graph 20 POINTS!

Margarita [4]

Answer:

Explanation to the answer below... (Answers in the Explanation)

Step-by-step explanation:

We Know that our rule is y = $y = -6(3)^{x}$ , which means we can use this rule to find y from x. Since we don't know what X, is, we have to assume numbers like 1, to 7. And there is no space to write on the graph, I'll put a virtual copy of a graph.

1st Point,

$y = -6(3)^{x}\\y = -6(3)^{1}\\y = -6(3)\\y = -18\\x = 1, y = -18$

2nd, point

$y = -6(3)^x\\ y = -6(3)^2\\y = -6(9)\\y = -54\\x = 2, y = -54$

3rd Point

$y = -6(3)^x\\y = -6(3)^3\\y = -6(27)\\y = -162\\x = 3, y = -162$

4th Point

$y = -6(3)^4\\y = -6(81)\\y = -486\\x = 4, y = -486\\$

5th Point

$y = -6(3)^5\\y = -6(243)\\y = -1458\\\x = 5, y = -1458$

6th Point

$y = -6(3)^x\\y = -6(3)^6\\y = -6(729)\\y = -4,374\\x = 6, y = -4,374\\$

7th Point (Last Point)

$y = -6(3)^x\\y = -6(3)^7\\y = -6(2,187)\\y. = -13,122\\x = 7, y = -13,122$

Let's now plot them on the Graph, the values are so big, the graph might look a little odd.

Always remember that we can continue the points infinitely, and there is no stop, The Graph is attached below...

A particle decays at a rate of 0.45% annually. assume and initial amount of 300 mg. (

raketka [301]

The increase is an exponential increase in a multiplier
$100%+0.45%=100.45%$ and as decimal 1.0045

Final Value = Initial Value × $multiplier^{number of years}$
Final value = $300(1.0045)^{60}$
Final value = 393 mg (to the nearest whole number)

Half life = 0.5 years
Final value = $300(1.0045)^{0.5}$ =301 mg

Laurie has a signed contract with I- Mobile where she will pay a $25 fee each month plus $2 per phone call.

nikitadnepr [17]

Answer:

i dont know how your teacher teaches it but in the first question take away the y after the 25. number 2 the start equation would be 55=2x+25 then you would subtract 25 from each side to get 30=2x, the divide by to to get x=15 or she made 15 calls. number 3 is correct.

i hope this helps
