Answer: The first one is "translated 4 units down". The second one is "vertically stretched by a factor of 4".

Recall that y = f(x). When we say f(x)-4, we really mean y-4 so that means each y coordinate of all the points on the graph have been reduced by 4. Visually this shifts the graph down 4 units. A translation in geometry is the technical term for shifting.

When we say 4*f(x), we are multiplying each y coordinate by 4. A point like (1,2) turns into (1,8) for instance. If you apply this to every point on the graph, then the curve is stretched vertically to be 4 times taller than it usually is; which is an informal way of saying "vertically stretched by a factor of 4"

Answer:

$121.95

Step-by-step explanation:

First, we need to change 45% into a decimal. To do that, move the decimal point two spaces back, and we will have 0.45.

Multiply that by the original price $84.10

$84.10 x 0.45 = 37.845

Then add 84.10 with 37.845

This adds up to $121.945, which you can round to $121.95

Amanda [17]

According to the number of cups, 564 people can be invited to the party.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. Total number of cups of yogurt is 423 cups

2. 1 serving = $\frac{3}{4}$ th of a cup

3. Each guest gets $\frac{3}{4}$ of a cup or 1 serving

4. Find out how many guests can be invited to the party,

Cups : People

$\frac{3}{4}$ : 1

423 : p

5. Cross multiply

$\frac{3}{4}$ p = 423 x 1

3p = 423 x 4

p = $\frac{1692}{3}$

p = 564

Therefore, according to the number of cups, 564 people can be invited to the party.
