PLEASE HELP ME FAST!The balance in two separate bank accounts grow each month at different rates. The growth rates for both accounts are represented by the functions f(x)=3^x and g(x)=5x+25. In what month is the f(x) balance greater than the g(x) balance? Show your work!​
P.S Whoever gives me a good answer and shows their work I will make as Brainliest!

Answers

Answer:

From fourth month onwards, the growth rate of f(x) is greater than that of g(x).

Step-by-step explanation:

Given:

The growth rates of both bank accounts are given as:

f(x)=3^x\ng(x)=5x+25

Now, as per question, we need to find the value of 'x' when the value of f(x)>g(x). Or,

3^x>5x+25

Now, we can do this by checking the values of 'x' by hit and trial method.

Let x=1. The inequality becomes:

3^1>5(1)+25\n3>30(False)

Let x=2. The inequality becomes:

3^2>5(2)+25\n9>35(False)

Let x=3. The inequality becomes:

3^3>5(3)+25\n27>40(False)

Let x=4. The inequality becomes:

3^4>5(4)+25\n81>45(True)

Therefore, the value of 'x' for which f(x)>g(x) is 4.

So, from the fourth month onwards, the balance in f(x) becomes greater than g(x).

The graphical solution is shown below to support the same.

From the graph, we can conclude that after the 'x' value equals 3.4, the graph of f(x) lies above of g(x). Hence, f(x)>g(x) for x>3.4

A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of 10 times and spent a total of 37 tickets Which equation is true?

Answers

Let x be the number of times that Michael rode on the roller coaster and let y be the number of times that he rode on the boat, then: x + y = 10 [because he went on the two rides a total of 10 times], and 4x + 3y = 37 [because a ride on a roller coaster costs 4 tickets and the boat ride costs 3 tickets and he spent a total of 37 tickets] From the first equation, 4x + 4y = 40 subtracting the second equation from the third equation gives: y = 3, and from the first equation x = 10 - y = 10 - 3 = 7 Therefore, Michael rode on the roller coaster 7 times and on the boat 3 times.

The answer is C. Hope this helps! :D

Do you remember how to find the equation of a line when you know two points on the line ? Well, that little table gives you FIVE points on the line, and in case some students didn't notice that, the table even labels the columns 'x' and 'y' as a hint. With 5 points given, there are 20 different ways to find the equation of the line. Get to work.
Okay first we need to find the line of best fit. We would need the slope and the y-intercept. First let's solve for slope.

Slope = (y_2 - y_1)/(x_2 - x_1)

We would need two coordinates from the table to fill in the data. Let's use (0, 23) and (1, 20).

(x_1, y_1) = (0, 23); (x_2, y_2) = (1, 20)

Then we can solve for the y-intercept using the slope-intercept form: y = mx + b.

a large cheese pizza coast $7.50. each additional topping for the pizza costs $1.35. if the total bill for the pizza sally orders was $12.90, how many toppings did she order?

Answers

Answer:

She ordered 4 toppings.

Step-by-step explanation:

7.5+1.35x=12.90

1.35x=12.9-7.5

1.35x=5.4

x=5.4/1.35

x=4
answer: 4
1) subtract 7.50 from 12.90. $5.40
2) divide 5.40 by 1.35. 4 toppings
