What’s the numbers or do you have a picture?

20=8+3(12+4x) Please help<br> It's really hard

nataly862011 [7]

So first, you have to remember the order of operations. That means that whatever is in the parentheses is what has to be done first
However, because one of the numbers in the parentheses is a variable and the other isn't, we can distribute instead
Therefore, 3(12+4x) distributes by multiplying the 3 into both numbers in the parentheses. So we get 36+12x
Now the equation is 20=8+36+12x
Now, bring all numbers without variables on the left side

20-8-36=8-8+36-36+12x
20-8-36=12x

Now simplify

20-8-36=12x
12-36=12x
-24=12x

Divide both sides by 12, and you get x=-2

Hope this helped!!! :D

The business was valued at £17000 at the start of 2011. In 6 years, the value of this business was raised to £186000. This is equivalent to a yearly increase of 49.0%.

Given that, A=£17000, P=£186000, r=x%, t=6 years

<h3>What is compound interest?</h3>

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

We know that, $A=P(1+\frac{r}{100} )^{n}$

Wow, $186000=17000(1+\frac{x}{100} )^{6}$

⇒ $10.94=(1+\frac{x}{100} )^{6}$

⇒ $1.4891=1+\frac{x}{100}$

⇒ $0.4891=\frac{x}{100}$

⇒x=48.91%~49.0%

Therefore, the value of x is 49.0%.

Look at the graph of the linear function. On a coordinate plane, a line goes through 4 points. Point A is (negative 2, negative

kondor19780726 [428]

Using it's concept, the rate of change between point C and point D is of 2.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:

$r = \frac{f(b) - f(a)}{b - a}$

Considering the points of the given linear function, we have that:

Point C: f(1) = 2.

Point D: f(2) = 4.

Hence the rate of change between point C and point D is given by:

r = (4 - 2)/(2 - 1) = 2.
