Answer:
y+9=3/4(x-8)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=3/4(x-8)
y+9=3/4(x-8)
Answer:
12 months
Step-by-step explanation:
Given that:
Mario:
12 stamps per month
Since January
Karen :
18 stamps per month
Starts on july
Number of stamps collected by Mario till the end of June :
12 * 6 = 72 stamps
For Mario :
72 + 12x
For karen:
18x
Where x is the number of months after karen starts :
Equate both equations
72 + 12x = 18x
72 = 18x - 12x
72 = 6x
x = 72/6
x = 12
After 12 months
Number of months after karen starts, will they have same amount of stamp
Answer:
this question
Step-by-step explanation:
D = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
d = sqrt( (5 - 2)^2 + (7 - 3)^2 )
d = sqrt( 3^2 + 4^2 )
d = sqrt(9 + 16)
d = sqrt(25)
d = 5
