In one hour he would cycle 18Km, therefore in a 1/4 hour the cyclist would ride a 1/4 of 18 = 4.5Km.
Answer:
(3, 6); (-3, 18)
Step-by-step explanation:
We equate the 2 expressions in x :-
x^2 - 2x + 3 = -2x + 12
x^2 - 2x + 2x + 3 - 12 = 0
x^2 - 9 = 0
(x - 3)(x + 3) = 0
So x = 3 or -3.
When x = 3, f(x) = -2(3) + 12 = 6.
When x = -3, f(x) = -2(-3) + 12 = 18.
Answer:
2/3
Step-by-step explanation:
The first fraction has to have the LCD of 24 because its what is divisible by 4 and 12
The first fraction has to be multiplied by 6/6 to get to the denominator of 24
The second fraction has to be multiplied by 2/2 to get to the denominator of 24
The first fraction then becomes
6/24
And the second fraction becomes
10/24
The answer would be 16/24 which simplifies to 2/3
