we know that
1) Lily swims a
-meter race
2) She swims the first half in
seconds
3) She swims the second half in
seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half

therefore
<u>the answer is</u>

Answer:
-20/3 & -40/3
Step-by-step explanation:
Let’s say that the 1st number is X and the 2nd number is Y.
Given that x:y = 1:2 => x/y = 1/2 => 2x = y
and a-5/y+4 = 5/4 (The first number is decreased by 5 and the second number is increased by 4.)
=> 4(x - 5) = 5 (y + 4)
=> 4x - 20 = 5y + 20
=> 4x - 5y = 40
As, 2x = y , 4x = 2y
=> 2y - 5y = 40
=> -3y = 40
=> y = -40/3 ; x = y/2 = -20/3
This might be confusing but I hope this helps :)
Answer:No solution
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
The 4 might be:
-1.9 - 3/2 , -1.8 and - 9/8.
The pairs of f(x) =-3x+5 can be found by putting value of x and getting f(x).
x=0, f(x)=5
X=-1, f(x) =3+5=8
x=1, f(x)= -3+5=2
So few ordered pairs arw (0,5) ,(1,2),(-1,8) etc.
