The slope of the given line is 5/4.  The slope of a line perpendicular to the given line is the negative reciprocal of 5/4, or -4/5.

Using the point-slope form, 

y - 5 = (-4/5)(x - 10).

This is the desired new line.

Note that mult. both sides by 5 removes the fractions:

5y - 25 = -4(x - 10), or     5y - 25 = -4x + 40.

Solving this for y:   5y = 25 - 4x + 40, or 5y = -4x + 65

Then y = (-4/5)x + 13 (answer)

Step-by-step explanation:

(22÷2)-0!=

Divide 22÷2 first bc its inside the parenthesis, get:

11 - 0! Next evaluate the factorial (yes, exclamation mark is a mathematical operation and 0! equals 1)

11 - 1 subtract

10

Next, 2+2+2+0! =

Would you rather have 1 million dollars or a dollar that doubles everyday?<br> explain your answer.
Eddi Din [679]
I would rather have a dollar that doubles every day, because you can soon reach past a million dollars and it will keep growing, instead of having 1 million dollars right away, and not gaining any more.
