Answer by JKismyhusbandbae: a^n = 4n + 1

Arithmetic Formula: a^n=5+4\left(n-1\right)

Use the following formula to determine any number in an arithmetic sequence:


an = a1 + d (n – 1)

a1 = the first term.

d = common difference

n = term number

Emily wins 22000$. She has to pay 10% for charity and then she decides to buy a car for 10800$. She divides the rest of them bet
devlian [24]

Answer:

$7 200

Step-by-step explanation:

Amount of money paid for charity = \frac{10}{100} × $22 000

                                                         = $2 200

Remaining money left for children = $22 000 - $2 200 - $10 800

                                                         = $9000

Let the amount of money her son receives be x and the amount her daughter gets be 4x.

Son's $ + Daughter's $ = $9000

x + 4x = 9000

5x = 9000

Amount of money her daughter gets (4x) = \frac{4}{5} × 9000

                                                                     = $7 200

1. For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.
Mars2501 [29]
The function is y=f(x)=-2x-3 

the graph of this function are all pairs (x, y)=(x, f(x))=(x, -2x-3)

the y-intercept of a graph of a function, is the point where the graph cuts the y-axis, which happens at x=0.

at x=0, f(x)=f(0)=-2*0-3=-3


the x-intercept(s) of the graph, are the point(s) where the graph intersects the x-axis. At those points, the y-coordinate is 0.

so the x-intercept(s) are points of the form (x, 0)

now, 

 (x, 0)=(x, -2x-3)

0=-2x-3
2x=-3
x=-3/2


Answer: 

x-intercept: (-3/2, 0)
y-intercept: (0, )
