Rename the end of the file from jpg to pdf.

so if your file name is "image.jpg"

rename the file from "image.jpg" to "image.pdf"

I learned this while trying to figure out how to make my google background a gif. It took me a while since this is the school's Chromebook ( Or because it's a Chromebook). 

I think all those squared distances are relatively easy to find using trigonometry.  Cosine Rule

Is that a good enough hint?

Seems the LARGEST negative 4 digit number would be 

-1011              - 1011 mod 23 = 1

Because    -1011 > - 9981       

    in other words  -1011 is larger  than -9981

there are 7 out of (7+5) ml of A used  :     7/12

7/12 * 612 = .........   ml of A

Have you tried the    ' image ' button to upload a pic?

Yes, subtract her expenses of 45 from the total she earned to get how much she 'made' .....

log 7^(2x+3)     =  (2x+3) log 7 = (2x+3)(.845098) = ...........

Why does the m in mod appear faded ?

It happens in other posts as well.

Angle V = 22 degrees

I don't like that they use the word "vertical" in the question. To me that would mean a line of the form x = -3.

I assume they mean "perpendicular" to.   

Even " y = -4/3x + 5" is slightly ambiguous   y = -4/(3x) + 5 or  y = (-4/3)x + 5 I assume the latter.

Solutions
3x + 4y = 0   solve for y . 
4y= -3x
y=-3/4*x  gives k =-3/4 for the original line 
k_{perpendicular} = -1/k = -1(1/(-3/4)) = -(-4/3) = 4/3   the only answer that fits that is d

Check does (-3, 1) exist on that line?
d) y = 4/3x + 5 = 4*(-3)/3 +5 = -4 +5 = 1  Yes

How did you get y = -4/3x -3  ?

If tan(x) = 3/4 what is cos(2x)?

tan(x) = 3/4       ∠x = 36.87º

cos(2x) = cos(2 * 36.87) = 0.28

3m + 1 + 2m + 4 = 180

angle PQT = (3m + 1) / 2

I was wondering if I should subtract the $45 or not. If it's just how much she made walking in gross income.

Thank you!

The answer is the second option.

The answer is 12.

(a) decreasing, odd, invertible

(b) increasing, invertible

(c) even, invertible, increasing

(d) even, decreasing

(e) invertible, even, decreasing

h + k + a + b = 13/10.

This assumes that y represents the money earned and that x represents how many "20min" she has walked. 2x represents the amount she earns every 20min, so we should subtract 45 from that to get y=2x-45. That corresponds to answer choice (d).

You walk each dog 20 minutes.

For every 20 minutes you get 2 dollars.

You walked 42 dogs.

You claim you are a "smartmathman".

You should easily know it's 2 dollars per dog, since you walk a dog for 20 minutes and each 20 minutes is 2 dollars.

*** edit ***   Left off the neg sign:

 - 34.2 = 0 + 0t - 1/2 (9.81) t^2     solve for 't'    

The distance between the lines is 4/3

Start by finding the time in the air

x = xo + vo t - 1/2 at^2

34.2 = 0 + 0t - 1/2 (9.81) t^2     solve for 't'    

   and continue.......

Find out how long it was travelling  

Horizontal @ 4.2 x 10^7 m/s   is constant

45 cm = .45 m

.45 m / 4.2 x 10⁷ m/s = ........... seconds

Then to find the vertical distance

yf = yo + vo t - 1/2 (9.81 m/s² ) t²

^{Yf is the distance you are looking for    yo = 0    vo= 0}    

yf = -1/2 (9.81)(t²)    using the 't' you found in the first step
