Squareroot(y-1) + 3 = y

Answers

note:xy means x times y and x(y) means the same thing

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

The box office manager said about 5000 people attended the show. Write a number that could be the actual attendance if he correctly rounded to the nearest hundred

Answers

Answer:

5000

Step-by-step explanation:

We are given that the box office manager said about 5000 people attend the show.

We have to write the number that could be actual attendance if he correctly rounded to nearest hundred.

In 5000

One's place=0

Tens place=0

Hundred place=0

Thousand place=5

The tens  place is less than 5 therefore, the hundred place and other place on the left side of tens place are remain same and other number on the right side of tens place replace by zero.

Then, the number is 5000.
