Squareroot(y-1) + 3 = y
Answers
so
first we get rid of square root then
make the equation equal to zero becaues if
xy=0 then x or/and y=0
squareroot(y-1)+3=y
isolate the squareroot
subtrac 3 from boht sides
squareroot(y-1)=y-3
square both sides (since they are equal, you should be able to square both sides and still make it true)
(squareroot(y-1))^2=(y-3)^2
(y-1)=(y-3)(y-3)
y-1=y^2-6y+9
subtrac y from both sides
-1=y^2-7y+9
add 1 to both sides
0=y^2-7y+10
find what two number multiply to make 10 and add to get -7
the answer is -2 and -5
0=(y-5)(y-2)
therfore
y-5=0
and/or
y-2=0
therefor
y=5 or/and 2 might work
let's try out 2
square root(2-1)+3=2
square root(1)+3=2
1+3=2
false
so 2 doesn't work
let's try 5
squareroot(5-1)+3=5
squareroot(4)+3=5
2+3=5
5=5
true
y=5

Answer:
hello : one possible dividend is 1003
Step-by-step explanation:
let a this dividend : a = 37q +4........( 4 is a remainde)
a > 1000
37q +4 > 1000
q > 996/37
but : 996/7 ≃ 26.91
q = 27 so: a = 37(27)+4 = 1003

Formula used here ,
It is given that the distance between Meredith and her friends house =2 4 blocks
Then At Speed = 1 block per minute.
= 24 minutes.
At Speed = 2 block per minute.
= 12 minutes.
At Speed = 3 block per minute.
= 8 minutes.
At Speed = 4 block per minute.
= 6 minutes.
At Speed = 6 block per minute.
= 4 minutes.
At Speed = 8 block per minute.
= 3 minutes.
At Speed = 10 block per minute.
= 2.4 minutes.
At Speed = 12 block per minute.
= 2 minutes.
At Speed = 24 block per minute.
= 1 minute.
This problem can be solved by using the formula for
linear motions. The formula relating velocity, distance and time is:
t = d / v
where t is time, d is distance and v is velocity
We are given that d = 24 blocks
When v = 1 block / minute
t = 24 blocks / (1 block / minute)
t = 24 minutes
When v = 2 block / minute
t = 24 blocks / (2 block / minute)
t = 12 minutes
Hence we can see that it takes half the time when she is
travelling at 2 blocks per minute.
