Answer:
2 digit Multiples of 5 are 10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95
Of 7 are 14,21,28,35,42,49,56,63,70,7784,91,98
Step-by-step explanation:
29
For the two digit numbers it has to end in a zero or five and be greater than 9 and below 100.
There are 18 multiples of 5 that are 2 digit
For multiples of 7... it's easier to write it out because the total number will will less than 20.
There are 13 multiples of 7 that are 2 digits
Now you have to subtract the multiples of 7 that end in a 0 or 5
That give you 11 multiples
Add 11 and 18 to get 29
k = -23
-14=k+9
Subtract 9 from each side
-14-9 = k+9-9
-23 = k
The equation of the given circle is X²+y²+4x- 12y+15=0
-1/3 the answer is negative one third
