Answer:

$\boxed{\sf{x=7 \quad y=2}}$

Step-by-step explanation:

To solve this problem, isolate it on one side of the equation.

x-3y=1: x=1+3y

x=1+3y

Substitute.

x=1+3y= 3(1+3y)-5y=11

Solve.

3+4y=11

Subtract by 3 from both sides.

3+4y-3=11-3

Solve.

11-3=8

Rewrite the problem down.

4y=8

Divide by 4 from both sides.

4y/4=8/4

Solve.

8/4=2

y=2

x=1+3y

x=1+3*2

Solve.

1+3*2

Multiply.

3*2=6

Add.

1+6=7

x=7

Therefore, the correct answer is x=7 and y=2.

I hope this helps you! Let me know if my answer is wrong or not.

(Step to step work) sin x(cotx + tanx)

11Alexandr11 [23.1K]

solving $sin(x)(cot(x) + tan(x))$ we get $sec(x)$

Step-by-step explanation:

We need to solve: $sin(x)(cot(x) + tan(x))$

Solving:

We know:

$cot(x)=\frac{cos(x)}{sin(x)}\\ and\,\,tan(x)=\frac{sin(x)}{cos(x)}$

Putting the values of cot(x) and tan(x):

$sin(x)(cot(x) + tan(x))\\=sin(x)(\frac{cos(x)}{sin(x)}+\frac{sin(x)}{cos(x)})$

Taking LCM:

$=sin(x)(\frac{cos(x)cos(x)+sin(x)sin(x)}{sin(x)cos(x)})\\=sin(x)(\frac{cos^2(x)+sin^2(x)}{sin(x)cos(x)})$

We know that: cos^2x+sin^2x=1

and using identity: cos(x)sin(x)=sin(2x)*1/2

$=sin(x)(\frac{1}{sin(2x)\frac{1}{2}})\\=sin(x)(\frac{2}{sin(2x)})$

Using identity: sin(2x)=2cos(x)sin(x)

$=sin(x)(\frac{2}{2sin(x)cos(x)})\\Cancelling\,\,same\,\,terms\,\,in\,\,numerator\,\,and\,\,denominator:\\=\frac{1}{cos(x)} \\=sec(x)$

So, solving $sin(x)(cot(x) + tan(x))$ we get $sec(x)$

What ages, in years, does the interval of 80-89 months represent

mart [117]

Well, there are 12 months in a year, so divide 80 and 89 by 12, which gives you 6 years and a remainder of 8 months, and 7 years with a remainder of 5 months. So your answer is 6 years 8 months- 7 years 5 months.

A distribution in which two nonadjacent values occur more frequently than any other values in a set of data is called a(n):_____

uysha [10]

In Bimodal Distribution two nonadjacent values occur more frequently than any other values in a set of data.

According to the statement

we have to tell about the that type of distribution in which two nonadjacent values occur more frequently than any other values in a set of data

A bimodal distribution has two peaks. In the context of a continuous probability distribution, modes are peaks in the distribution.

and from this definition we have clear that the in this distribution the values are repeated.

it shows the probability distribution with two peaks in the graphical mode.

Bimodal distribution show repeated value.

it is used in many types of data representation because of two peaks graphical representation than the simple graph.

it is the easiest method than the others distributions.

So, In Bimodal Distribution two nonadjacent values occur more frequently than any other values in a set of data.
