Answer: (3, 5)

<u>Step-by-step explanation:</u>

y = x + 2 is already in Slope-Intercept format

b = 2: Plot +2 on the y-axis
m = 1: Count up 1 and right 1 from "b" to plot the next point

y = -x + 8 is already in Slope-Intercept format

b = 8: Plot +8 on the y-axis
m = -1: Count down 1 and right 1 from "b" to plot the next point

(Step to step work)<br><br> 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 $sec(x)$
