6 0

Step-by-step explanation:

1 is the starting point since it is on the the axis.

then you would use the rise over run method to get the fraction. it rises by two and runs by 1 which would get you 2/1. so the answer should be y=1+2/1

(it is an addition sign since it is a positive slope)

A sequence is defined by the recursive function f(n + 1) = -

Sauron [17]

Answer:

100

Step-by-step explanation:

f(n+1)=-10 f(n)

f(1)=1

put n=1

f(2)=-10f(1)=-10×1=-10

put n=2

f(3)=-10f(2)=-10×-10=100

What is the average rate of change for the sequence shown below?

ryzh [129]

Answer:

$\large\boxed{-1\dfrac{1}{2}}$

Step-by-step explanation:

The points on the graph are collinear (they lie on one straight line).

Therefore, average of change is the same as a slope.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We choose two points and put the coordinates to the formula

$(1, 4), (3, 1)\\\\\dfrac{1-4}{3-1}=\dfrac{-3}{2}=-1\dfrac{1}{2}$

HELP. there are 45 coins consisting of nickels, dimes and quarter making a total of 7 dollars. the number of dimes exceeds the n

MA_775_DIABLO [31]

9514 1404 393

Answer:

Step-by-step explanation:

Let n, d, q represent the numbers of nickels, dimes, and quarters, respectively. Then we have ...

n + d + q = 45

5n +10d +25q = 700

n -d = -5

Using n=d -5, we can substitute into the first two equations:

(d -5) +d + q = 45

2d +q = 50 . . . . add 5, collect terms [eq4]

5(d -5) +10d +25q = 700

15d +25q = 725 . . . . . . . . . . add 25, collect terms [eq5]

Multiplying [eq4] equation by 3 and subtracting that from 2/5 of [eq5], we have ...

(2/5)(15d +25q) -3(2d +q) = (2/5)(725) -3(50)

6d +10q -6d -3q = 290 -150

7q = 140 . . . . . . simplify

q = 20 . . . . . . . . divide by 7

There are 20 quarters.

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, slope can be found using

y2-y2

x2-x1

So we just plug it in:

7-0

2+3

7/5 is your slope
