Answer:
(x-1)/13
Step-by-step explanation:
y = 13x+1
To find the inverse, exchange x and y
x = 13y+1
Solve for y
Subtract 1 from each side
x-1 =13y+1-1
x-1 = 13y
Divide each side by 13
(x-1)/13 = y
The inverse is (x-1)/13
Between emma and dave, we have 7/10ths of the money
3x + 2x = 7/10
5x = 7/10
x=(7/10)/5
x= 14/100
Dave will get 28/100 or 7/25ths
Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave
-----------
100/00
Answer:
point form: (1,-2)
Equation Form: x = 1, y = -2
Step-by-step explanation:
Let the length of one leg be x then another leg is (x+2)
According to Pythagoras theorem,
x^2 + (x+2)^2=16^2
=> x^2 + 2x - 126 =0
=>x= √(126 - 1) = 10.225
By sreedharchaya's formula
