Y=4x+8x, Solve for x. It's x=y/12, I just need to know how to work it out.

Scrat [10]

Step-by-step explanation:

<h2>Answer:-</h2>

$\tt{y = 4x+8x}$

First, we need to add up the x.

We know that 4+8 = 12, so

$\tt{4x+8x=12x}$

Now, equating it to y,

$\tt{y = 12x}$

Now, if I multiply $\tt{\dfrac{1}{12}}$ on both sides,

I get,

$\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}$

Now, as 12 got cancelled , I got the final answer as

$\boxed{\tt{x =\dfrac{y}{12}}}$

Hope it helps :)

Using the formula in model 1, choose the correct answers for the total amount and amount of interest earned in the following com

DIA [1.3K]

The total amount is $ 1015.82 and interest amount is $ 165.82

Solution:

The formula for amount when interest is compounded annually is:

$\mathrm{A}=P\left(1+r}\right)^{n}$

Where,

"A" is the total amount

"P" is the principal

"r" is the rate of interest in decimal form

"n" is the number of years

From given, $850 at 2% for 9 years, compounded annually

P = 850

t = 9 years

$r = 2 \% = \frac{2}{100} = 0.02$

Substituting the given values we get,

$A = 850(1+0.02)^9\\\\A = 850 \times 1.02^9\\\\A = 850 \times 1.1950\\\\A = 1015.82$

Thus total amount is $ 1015.82

Interest amount = Total amount - principal

Interest amount = 1015.82 - 850

Interest amount = 165.82

Thus total amount earned is $ 1015.82 and interest amount is $ 165.82

Y=x3 is that a function?

kotykmax [81]

Answer:

yes

Step-by-step explanation:

y(x) is even or odd according as y(−x)=±y(x) . Here, #y(-x)=-(-x)^3=-(-x^3)=x^3=-y(x). So, y is an odd function of x.

if the measure of <BEC is (2x+3)° and x=30, which expression could represent the measure of <AED?

Maurinko [17]

Answer:

The answer is 3x-27

Step-by-step explanation:

If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.
