Draw a line with the given slope through the given point.

(-4,1) slope=3/5

Answers

I can't put. Graph out but I can give you points. Since it says 3/5 you must go up three and over five(my teacher likes to call it the rise/run method). So here are the points

(1,4)

(6,7)

And the point you already gave, (-4,1). Hope this helped!

Find the slope of the line that passes through each pair of points A(0,1), B(2,7)

Answers

$\sf Slope = (y_2-y_1)/(x_2-x_1) = (7-1)/(2-0) = (6)/(2) =\boxed{3}$

The slope of the line that passes through points (0,1) and (2,7) is 3

the slope would be 3.
7-1=6
2-0= 2
6/2=3

Answer: $(sin (4x))/(cos(14 x))$

Step-by-step explanation:

We have the following expression:

$(tan(9x)-tan(5x))/(1+tan(9x)tan(5x))$

In order to work in a better way this expression, let's call $\alpha=9x$ and $\beta=5x$ and rewrite:

$(tan(\alpha)-tan(\beta))/(1+tan(\alpha)tan(\beta))$

Now, we know $tan \theta=(sin \theta)/(cos \theta)$ . Let's apply it here:

$((sin (\alpha))/(cos(\alpha))-(sin(\beta))/(cos(\beta)))/(1+(sin (\alpha))/(cos(\alpha))(sin(\beta))/(cos(\beta)))$

$((sin(\alpha)cos (\beta)-sin(\beta)cos(\alpha))/(cos(\alpha)cos(\beta)))/((cos(\alpha) cos(\beta)+sin(\alpha) sin(\beta))/(cos(\alpha)cos(\beta)))$

Simplifying:

$(sin(\alpha)cos (\beta)-sin(\beta)cos(\alpha))/(cos(\alpha) cos(\beta)+sin(\alpha) sin(\beta))$

According these trigonometric identities, we have:

$sin(\alpha-\beta)=sin(\alpha)cos (\beta)-sin(\beta)cos(\alpha)$

$cos(\alpha+\beta)=cos(\alpha) cos(\beta)+sin(\alpha) sin(\beta))$

Then:

$(sin(\alpha-\beta))/(cos(\alpha+\beta))$

Writing again the actual values:

$(sin(9x-5x))/(cos(9x+5x))$

Finally:

$(sin(4x))/(cos(14x))$

Are the ratios 3:7 and 1:2 equivalent

Answers

No, because 7 is prime (i’m pretty sure they aren’t)

Answer: No

Step-by-step explanation:

Finding equivalent ratios is just like finding equvalent fractions.

For Example: 3/6 = 1/2 that also means 3:6 will equal 1:2

Good Luck!
