Y = -2x - 5

lions [1.4K]

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

$y = -2\cdot x - 5$

$6\cdot x + 3\cdot y = -15$

$3\cdot y = -6\cdot x - 15$

$y = -2\cdot x - 5$

The second equation is identical to the first one, which means that there is just one line.

HELP ASAP PLEASE!!! 20 POINTS!!

Answer: $S_{12}=399.90$

Step-by-step explanation:

You know that the formula to find the sum of a finite geometric series is:

$S_n=\frac{a_1(1-r^n)}{1-r}$

Where $n$ is the number of terms, $a_1$ is the first term and $r$ is the common ratio ( $r\neq 1$ ).

The steps to find the sum of the first 12 terms of the given geometric serie, are:

1. Find the common ratio "r". By definition:

$r=\frac{a_2}{a_1}$

Then:

$r=\frac{100}{200}\\\\r=\frac{1}{2}$

2. Finally, knowing that:

$a_1=200\\\\n=12$

You must substitute values into the formula.

Then you get:

$S_{12}=\frac{200(1-(\frac{1}{2})^{12})}{1-\frac{1}{2}}\\\\S_{12}=399.90$

the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of

Gemiola [76]

So, if "d" equals the diameter, we need to plug in 1.5 for "d". The equation now looks like: f(h) = 2(1.5) +4.3. Now if you multiply, it's: f(h) = 3 + 4.3, which then is: f(h) = 7.3. The height would be 7.3 in, when the diameter is 1.5 in. Hope this helps =). Have a great day!
