Solve for all possible values of x.

KATRIN_1 [288]

Answer:

Option d) x = 25

Step-by-step explanation:

we have

$\sqrt{x-9}+4=8$

Solve for x

Subtract 4 both sides

$\sqrt{x-9}+4-4=8-4$

$\sqrt{x-9}=4$

squared both sides

$(x-9)=(+/-)4^2$

$(x-9)=(+/-)16$

Adds 9 both sides

$x=9(+/-)16$

$x1=9(+)16=25$

$x2=9(-)16=-7$

Verify

1) For x=25

$\sqrt{25-9}=4$

$\sqrt{16}=4$

$4=4$ ----> is true

therefore

x=25 is a solution

2) For x=-7

$\sqrt{-7-9}=4$

$\sqrt{-16}=4$

The radicand cannot be a negative number

therefore

x=-7 is not a solution

At the movies a bag of popcorn cost $3.50 and a bottle of water coast $2.75. If Madeline has $18 and bought two bottles of water

Multiple the cost of the water bottle ($2.75) then whatever you answer is, you subtract that from 18. She should have $12.5 left. The most bags of popcorn she could get is 3. Just add $3.50 until it’s closes to the amounts of money she has left.
