Find the x-intercept of the line 20x - 17y = 15.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.

Answer 1
Answer:

Step-by-step explanation:

the line is

20x - 17y = 15

I am not sure what your teacher uses as "standard form".

the works is split between "point-slope" and "slope-intercept" form as "standard".

I usually pick "slope-intercept" :

y = ax + b

with a being the slope and b being the y-intercept.

in any case, we can find the x-intercept without bringing the line equation to one of these forms.

because x-intercept simply means that y = 0.

and for y=0 the original equation is then

20x - 17×0 = 15

20x = 15

x = 15/20 = 3/4
Answer 2
Answer:

Final answer:

The x-intercept of the line 20x - 17y = 15 is the value of x when y equals zero. Using this condition, the equation becomes 20x = 15. Solving for x, we get x = 15/20 or x = 3/4.

Explanation:

To find the x-intercept of the line 20x - 17y = 15, we first set y to zero because the x-intercept is the value of x when y equals zero.

So, we have 20x - 17(0) = 15, which reduces to 20x = 15. Then we solve for x by dividing both sides by 20, obtaining x = 15/20 or 3/4.

Therefore, the x-intercept of the equation 20x - 17y = 15 is 3/4.

21

Step-by-step explanation:

This is a combination of 7 objects taken 5 at a time

nCr = n! / r! * (n - r)!

7C5 = 7! / (5! (7-5)!)

       = 7! /(5! 2!)

       = (7*6*5*4*3*2*1)

A photographer is printing a photograph for a client. The ratio of the photograph’s width to its length is 8:10. The client wants a smaller version of the photograph printed, but the ratio of the width to the length needs to stay the same. If the length of the printed photograph is 5 inches, what should the width be?
3 inches 4 inches 6 inches 7 inches 8 inches

Answers

The ratio is 4:5

because 8 divided by 2 is 4

and 10 divided by 2 is 5

so the answer as said before is 4:5

I hope this helps :)
