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

<u><em>Verify </em></u>

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

Solve number problem 8
butalik [34]

Two consecutive odd integers have a difference of 2. If you let the smaller one of them be x, the other one is x + 2.

Their sum is -36, so add x and x + 2, and set equal to -36. Then solve for x to find the smaller one. Finally, 2 more than x is the greater of the two integers.

x + x + 2 = -36

2x + 2 = -36

2x = -38

x = -19

The smaller one of the two integers is -19.

x + 2 = -19 + 2 = -17

The greater of the two integers is -17.

Answer: The integers are -19 and -17.

Anettt [7]

ANSWER

36 .19

EXPLANATION

We want to estimate

47\% \: of \: 77

This is the same as

\frac{47}{100}  \times 77

or

\frac{47}{100} \times  \frac{77}{1}

We multiply the numerators to get,

\frac{3619}{100}

We convert to decimals to get

36.19
