What is the solution to the equation below? Round your answer to two

noname [10]

Answer:

D. x=5

The answer is x=4.50 then it is rounded off to 5. So, the answer is 5.

Step-by-step explanation:

Find the domain of the inequality: $2x-1\geq 0$

Rearrange terms to the left side of the equation: $2x\geq 1$

Divide both sides of the inequality by the coefficient of the variable:

=> $x\geq \frac{1}{2}$

The domain of the inequality is: $x\geq \frac{1}{2}$

Convert logarithm to exponential form: $2^{3}=2x-1$

Calculate the power: $8=2x-1$

Rearrange terms to the left side of the equation: $-2x= -8-1$

Calculate: $-2x=-9$

Divide both sides of the equation by the coefficient of the variable: $x=\frac{-9}{-2}$

=> $x=\frac{9}{2}$

=> $x=4.5\\$

Round the number: $x=4.50$

Answer: $x=4.50$

=> $x=5$

Stephanie is making beef for a party the recipe uses 1 1/2 teaspoons of pepper, 3 2/4 teaspoons of garlic powder 1/8 teaspoons o

Arisa [49]

Answer:

She will use:

3 tablespoons of pepper

7 tablespoons of garlic powder

$\frac{1}{4}$ tablespoon of thyme

8 tablespoons of onion powder

Explanation:

To double the amount, Stephanie will need to double the amount of each ingredient used. This means that she will multiply each amount by 2

Therefore:

New amount of any ingredient = old amount of that ingredient x 2

This means that:

New amount of pepper = $1\frac{1}{2}*2= 3$ tablespoons

New amount of garlic powder = $3\frac{2}{4}*2=7$ tablespoons

New amount of thyme = $\frac{1}{8}*2=\frac{1}{4}$ tablespoons

New amount of onion powder = $4*2=8$ tablespoons

Hope this helps :)

Find the equation of the line.

zhuklara [117]

Answer:

y=-1/3x-2

Step-by-step explanation:

First off, lets outline that parallel lines have the Same Slope. So we can plug in -1/3 as our slope, or m.

Lets plug in -1/3 as our slope in Point Slope form to find the y intercept. Point slope form should be attached in an image below.

1) Plug slope and points into point slope form:

y+1=-1/3(x+3)

2) Distribute -1/3 to x and 3:

y+1=-1/3x-1

3) Subtract 1 from both sides:

y=-1/3x-2

Now we have our answer is slope intercept form!

Please let me know if you have any questions :)
