12am=4 Divide both sides by "12m" to have "a".. Thus, a=4/12m since 4/12 is reducable to d lowest term, we have the final answer to be: a=1/3m OR a=(1/3)/m

First, divide both sides by 12 to get am alone
am=1/3
Now, divide both sides by m to get a alone
a=1/3 / m

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

maxonik [38]

ANSWER

$2 \frac{1}{4}$

EXPLANATION

We want to find the constant that must be added to

${x}^{2} - 3x$

to form a perfect square.

Comparing the given expression to

$a{x}^{2} + bx + c$

we have

a=1 , b=-3 , and c=0.

We need to add

${( \frac{b}{2a} })^{2}$

We substitute the values to get,

${( \frac{ - 3}{2(1)} })^{2} = \frac{9}{4}$

We change this to mix numbers to get,

$2 \frac{1}{4}$

The last choice is correct.

Can someone please help I’m very confused

Oxana [17]

y + 6 = 4/3(x - 2)

First, distribute the 4/3

y + 6 = 4/3x - 8/3

Subtract 6 from both sides.

y = 4/3x - 26/3

-26/3 is the y-intercept so start the graph at coordinate (0, -26/3)

After you plot the y-intercept, add 4 to they y-coordinate and 3 to the x-coordinate of the y-intercept to get the next point.

0 + 3 = 3

-26/3 + 4 = -14/3

The next point should be at (3, -14/3)

Add as many points as your professor requires.

Hey there :)

An exact answer cannot be given as it requires to reseach about banks and co-operatives in your locality. However, I can give you a hint.

Research banks or cooperatives in your location that has the greatest percentage in terms of investment or savings.

Let's say, for example, Bank ABC has 5% annual simple interest in their Savings Account.

If you invest your entire money 100,000 pesos at Bank ABC with 5% annual interest for 20 years, you will earn an interest of:

$Interest = Principal \times Rate \times Time$

$= > Interest =100000 \times 0.05 \times 20yrs$

$= > Interest = 100000$

Hence, after investing at Bank ABC for 20 years, you will earn 100,000 pesos on top of your principal/invested amount that is 100,000 pesos. Your money will become 200,000 pesos now.

So, with this, find a bank/cooperative that has the highest return rate in your location. Once you have decided bank/cooperative, research further with regards to the background of the company, other services offered, application requirements, etc.
