Given

Coordinates of Point A is $(-3,-4)$ i.e. Point A is 3 units to the left and 4 units below x-axis

From figure, we can write

$\Rightarrow \tan \theta =\dfrac{3}{4}\\\\\Rightarrow \theta=\tan^{-1}\left(\dfrac{3}{4}\right)\\\\\Rightarrow \theta=36.86^{\circ}$

What is 11.52/128 show your work

grandymaker [24]

Answer:

The answer is

Step-by-step explanation:

11.5/128

First convert the decimal to an improper fraction

That's

$11.52 = \frac{288}{25}$

So we have

$\frac{288}{25} \div 128$

Change the division sign to multiplication sign and reverse the second number

That's

$\frac{288}{25} \times \frac{1}{128}$

Simplify

$\frac{288}{3200}$

Divide through by 32

The final answer is

$\frac{9}{100}$

Hope this helps you

Determine the intercepts of the line. Do not round your answers. 2x+5y=-6, y x-intercept:

NikAS [45]

The required x and y-intercept of the given line is -3 and -6/5 respectively.

<h3>What is the slope of the line?</h3>

The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The given equation of the line is 2x+5y=-6.
Transform into standard form of line .i.e is y = mx + c

5y = -2x - 6
y = -2x/5 - 6/5
here , m = -2/5 and c = -6/5
Since c = y-intercept of the line = -6/5
Now, put y = 0 in the equation of the line.
2x = -6
x = -3

Thus, the required x and y-intercept of the given line is -3 and -6/5 respectively.

PLEASE HELP SOON! ALSO INCLUDE A SMALL EXPLANATION as well as the answer ! I am rewarding 100points if you answer quickly

alina1380 [7]

Answer:

the answer is B

f(x)=-2x+3

Step-by-step explanation:

to get the -2x I did --->

pick two points I used (0,3) and (1,1) and used the equation $\frac{y2-y1}{x2-x1}$

where y2 would be 1 and y1 would be 3

and where x2 would be 1 and x1 would be 0

so you would put the numbers in the equation which would look like $\frac{1-3}{1-0}=\frac{-2}{1}$ and equal -2 which would be -2x in the answer

And the +3 is the y-intercept
