I’m guessing you mean as a decimal. So it would be 2.333333333333 (repeating 3)
Answer:
- -9
- 2x + 3y = 21
- 4√5
Step-by-step explanation:
1. Put the point values in the equation where x and y are, then solve.
... 3(-2) -2k = 12
... -6 -2k = 12 . . . . eliminate parentheses
... -2k = 18 . . . . . . .add 6
... k = -9 . . . . . . . . . divide by -2
2. The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line. The equation for it can be found by swapping the x- and y-coefficients and negating one of them. Then, to make the line go through point (h, k), replace the constant with zero and replace x with (x-h) and y with (y-k).
... 2(x -6) +3(y -3) = 0 . . . . . a line through P perpendicular to PQ
... 2x + 3y = 21
3. The Pythagorean theorem is used for finding the lengths of line segments. The difference in coordinates between P and R is ...
... P - R = (6, 3) - (2, -5) = (6-2, 3-(-5)) = (4, 8)
The length of segment PR can be considered to be the length of the hypotenuse of a right triangle with these leg lengths.
... ║PR║ = √(4² +8²) = √80
... ║PR║ = 4√5
On day one she starts of with 1 hour so it will be 1+30x. X being the number of days so by the seventh day Anna would practice for 240 minutes.
10 is the answer hope that's what it was
Answer:
56 times (This is still assuming 1 isnt an option)
Step-by-step explanation:
0,2,3,4,5,6,7,8
There are 8 options, 3 of which are greater than 5
3/8
3/8 = x/150
3*150 = 450
8 * x = 8x
8x = 450
450/8 = 56.25
56 times
