What is the equation of the line with the given slope and y-intercept? Choose the correct answer in slope-intercept form and sta

kari74 [83]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y-intercept )

here m = $\frac{1}{3}$ and b = 13, hence

y = $\frac{1}{3}$ x + 13 ← in slope- intercept form

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and AB, C are integers )

multiply all terms in the slope-intercept form by 3

3y = x + 39 ( subtract 3y from both sides )

0 = x - 3y + 39 ( subtract 39 from both sides )

x - 3y = - 39 ← in standard form

If sin theta = 2/3 and tan theta <0 what is the value of cos theta?

Mrac [35]

Answer:

d) $\cos(\theta)=-\frac{\sqrt{5}}{3}$

Step-by-step explanation:

If $\sin(\theta)=\frac{2}{3}$ and $\tan(\theta)\:$ , then

$\theta$ is in quadrant 2.

Recall that;

$\sin^2(\theta)+\cos^2(\theta)=1$

We substitute the given sine ratio to obtain;

$(\frac{2}{3})^2+\cos^2(\theta)=1$

$\frac{4}{9}+\cos^2(\theta)=1$

$\cos^2(\theta)=1-\frac{4}{9}$

$\cos^2(\theta)=\frac{5}{9}$

$\cos(\theta)=\pm \sqrt{\frac{5}{9}}$

$\cos(\theta)=\pm \frac{\sqrt{5}}{3}$

We are in the second quadrant, therefore

$\cos(\theta)=-\frac{\sqrt{5}}{3}$

Select the sentence that is written informally.

alex41 [277]

Answer:

I would assume that "It's always awesome to check out new video games" is the informal sentence.

Step-by-step explanation:

Awesome is an informal word as it is a slang, words that qualify to be used formally but resemble "Awesome" include "Astonoshing", "Astounding", "Fabulous" and such.

Find an equation of a line that has a slope 1/4 and Y intercept zero -8 then graft equation using the slope and Y intercept

LenKa [72]

Answer:

y = 1/4x - 8

Step-by-step explanation:

So we do not have the capabilities of graphing but I will help you find the equation.

Slope intercept form: y = mx + b

b = y intercept

m = slope

Put your equation together.

y = 1/4x - 8
