On a graph the point is (2,2) is it enough information to plot if yes what's the equation of it if not say no

lisov135 [29]

To plot a point on a graph, you need the x and y coordinates.

In this case, the x-coordinate is 2 and the y-coordinate is 2 thus you can plot

(2,2) on a graph.

To get the equation of a line, you need the slope m of the line, a point and another imaginary point (x,y). So in this question you still need the slope to find the equation.

The equation is : No

Answer

1. The point can be plotted on a graph

2. No, the equation can not be determined because the gradient is not known.

Find the number of terms in the arithmetic progression 2,-9,-20,...,-141

Vinil7 [7]

Answer:

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 , d = - 9 - 2 = - 11 and $a_{n}$ = - 141, thus

2 - 11(n - 1) = - 141 ← distribute and simplify left side

2 - 11n + 11 = - 141

13 - 11n = - 141 ( subtract 13 from both sides )

- 11n = - 154 ( divide both sides by - 11 )

n = 14

That is the progression has 14 terms

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

P is principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 9500

r = 4.5% = 0.045

t = 5

Step 2: Find A

Substitute in variables [Simple Interest Rate Formula]: A = 9500(1 + 0.045)⁵
(Parenthesis) Add: A = 9500(1.045)⁵
Evaluate exponents: A = 9500(1.24618)
Multiply: A = 11838.7
