Hello!

Let's write this as an equation below.

3x+4=16

We subtract 4 from both sides.

3x=12

Divide both sides by 3

x=4

I hope this helps!

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 :)

Describe what happens to the graph of y=3x + 4 when the slope is changed 1/3 one over three

kumpel [21]

Answer:

see the explanation

The graph in the attached figure

Step-by-step explanation:

we have

$y=3x+4$

This is a linear equation (the graph is a line)

The y-intercept is the point (0,4) ---> value of y when the value of x is equal to zero)

The x-intercept is the point (-4/3,0) ---> value of x when the value of y is equal to zero)

The slope is m=3

If the slope is changed to m=1/3

we have

$y=(1/3)x+4$

This is a linear equation too (the graph is a line)

The y-intercept is the point (0,4) ---> is the same

The x-intercept is the point (-12,0) ---> the x-intercept is different

The slope is m=1/3

The second line becomes a lot less steep

Remember that the slope is the ratio between the rise and the run

In the first line the ratio rise/run is 4/1

In the second line the ratio rise/run is 1/3

see the attached figure to better understand the problem
