Please help!!!!!!!!!!!!!!!!!!!!

Ahat [919]

Greetings!

"Write and solve an equation to determine how many servings of this item ...exactly 45 grams of cholesterol"...

The variable in this equation would be the amount of servings she can eat of the items.
Lets represent this as $x$ ; $x$ =amount of servings

The item has 30 mg of cholesterol and she wants to only consume 45 mg.

The equation would be:
$30x=45$

Solve for x.
Divide both sides by 30.
$(30x)/30=(45)/30$
Simplify.
$x=1.5
$

Alisa can consume 1.5 servings of the item each day.

Hope this helps.

Find the common ratio for the following sequence. 0.1, 0.01, 0.001, ... 0.01 0.1 0.001

Zinaida [17]

Answer:

$\frac{1}{10}$

Step-by-step explanation:

$a_1 = 0.1\\a_2 = 0.01\\a_3 = 0.001$

$r = \frac{a_2}{a_1}$

$r = \frac{0.01}{0.1}$

$r=0.1$

Which of the following is an example of a function?

Leokris [45]

A. Not a function since we have the points (-1,0) and (-1,3). The x value repeats while the y values are different. Plugging in x = -1 leads to multiple outputs, which shows we don't have a function. To get a better visual, you can plot the points. You'll see that the points form a vertical line. Therefore, this graph fails the vertical line test.

B. This is a function. All of the x values are different. The points, when graphed, pass the vertical line test. In other words, its impossible to draw a vertical line through any two points on the graph. Any x input here leads to exactly one y output.

C. This is not a function. Like choice A, we have repeated x values. In this case we have (4,6) and (4,7). The x value x = 4 repeats itself leading to multiple outputs y = 6 and y = 7

D. This is also not a function. The x value x = 0 repeats itself. The graph fails the vertical line test.

Answer: Choice B
