consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen

katovenus [111]

When you write a function in the form $y=f(x)$ , y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

$16b = 4r - 12$

Add 12 to both sides

$16b+12 = 4r$

Divide both sides by 4:

$4b+3 = r$

So, we wrote the expression in the form $r = f(b) = 4b+3$ , which means that r is the dependent variable and b is the independent variable, as requested.

Answer:

$\frac{1}{3}x+16=37$

63 Jelly Beans

Step-by-step explanation:

The unknown is the number of jelly beans originally in the bag or x

First he had x jelly beans

The he ate one-third of them

$\frac{1}{3}x$

He then ate 16 more jelly beans

$\frac{1}{3}x+16$

This was equal to 37 jelly beans

$\frac{1}{3}x+16=37$

This is the equation

Now solve for x

Subtract 16 from both sides

$\frac{1}{3}x=21$

Multiply both sides by 3

$x=63$

1.Lin and her brother each created a scale drawing of their backyard, but at different scales. Lin used a scale of 1 inch to 1 f

IceJOKER [234]

Answer:Part 1) The scale for the drawings without units are 1/12 and 1/36

Part 2) The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36. The explanation in the procedure

Step-by-step explanation:we know that

1) Lin used a scale of

Remember that

1 ft=12 in

substitute in the scale

That means ----> 1 unit in the drawing represent 12 units in the actual

2) Her brother used a scale of

Remember that

1 yd=36 in

substitute in the scale

That means ----> 1 unit in the drawing represent 36 units in the actual

therefore

The scale for the drawings without units are 1/12 and 1/36

Part 2) Whose drawing is larger?

The scale drawing 1/12 is larger than the scale drawing of 1/36

To find out how many times as large is the scale 1/12 than the scale of 1/36

Divide 1/12 by 1/36

The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36

Explanation

Let supposing that we want to represent in the drawing a measure that in its real size measures 36 units.

In the scale of 1/12, the drawing will show a measure of 3 units (remember 3(12)=36 units).

At the 1/36 scale, the drawing will show a measurement of 1 unit (remember 1(36)=36 units).

Therefore the largest drawing will be with a scale of 1/12.
