Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many b
topjm [15]

Answer:

18f - 6 bottles

Step-by-step explanation:

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda. Carla collects 3(5 + 2f) bottles. How many bottles did they collect altogether in terms of f ?

From the question

Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda.

= 2(4f - 3)

= 8f - 6 bottle caps

Carla collects 3(5 + 2f) bottles.

= 15 + 6f bottles

The number of bottles they collected altogether in terms of f is calculated as:

(4f – 3) bottle + 8f - 6 bottle + 15 + 6f bottle

4f - 3 + 8f - 6 + 15 + 6f

= 18f - 6

The graph of the logarithmic function f(x) = loga(x) passes through the points and . The graph lies the y-axis.
vagabundo [1.1K]
The question is incomplete. But this explanation will help you very much.

1) Regarding the function      log_ax   , its graph always passes through the points (1,0) and (a,1).

That is due to the properties of logarithm function:

a)    log_a1=0

b)    log_aa=1
<span> 
That in turn is due to the properties of the exponential functions.

a^0 = 1 and a^1 = a
</span>
2) Regarding the y-axis.

The function log_ax will never touch the y-axis, because the logaritm of zero is not defined. So the graph lies to the righ of the y-axis (i.e. the domain of the function is x > 0)

The price of a car is 4000 dollors .The price is reduced by 15%,What is the price of reduction and Find the new price of the car
Natali [406]

The price reduction on the car price is $600

The new price of the car is $3,400

What is the initial price of the car?

The initial selling price of the car was $4,000, which is seen 100% of the price, which means that a 15% decrease implies that the price would go down by 15% from 100% to 85%.

Price reduction=15%*price of the car

Price reduction=15%*$4,000

Price reduction=$600

What is the new price of the car?

The new price of the car is the initial price of $4,000 minus the price reduction

new price of the car=$4,000-$600

new price of the car=$3,400
