To answer, we first divide both sides of the equation by -2.3 giving us a new equation which is,
x - 1.2 = 4.2
Then, we add 1.2 to both sides of the equation,
(x - 1.2) + 1.2 = 4.2 + 1.2
x = 5.4
The value of x is 5.4.

Answer:

It's right :)

Explanation:

Dilation along the x-axis = (-7-1)/(-1-1) = 2/8 = 1/4
Dilation along the y-axis = (-7-1)/(-1-1) = 2/8 = 1/4

Thus, the overall dilation is 1/4

Find the 100th and the nth term for each of the following sequences.80,140,200

Alina [70]

Answer

a(n) = 60n + 20

a(100) = 6020

Step-by-step explanation:

Given the following sequences

80, 140, 200

$\begin{gathered} \text{The given sequence is }80,\text{ 140, 200} \\ \text{Step 1: find the common difference} \\ \text{common difference= next term - previous term} \\ \text{Common difference = 140 - 80} \\ \text{Common difference = 60} \\ \text{common difference = 200 - 140} \\ \text{common difference = 60} \\ \text{Hence, the common difference is 60} \\ \text{The nth term of an arithmetic progression is} \\ a(n)\text{ = a + (n - 1) x d} \\ \text{where a = first term, n = no of terms, and d = common difference} \\ a(n)\text{ = 80 + (n - 1) x 60} \\ \text{open the parenthesis} \\ a(n)\text{ = 80 + 60n - 60} \\ a(n)\text{ = 60n + 80 - 60} \\ a(n)\text{ = 60n + 20} \\ \\ \text{ Find the 100th term} \\ \text{let n = 100} \\ a(100)\text{ = 60(100) + 20} \\ a(100)\text{ = 6000 +2}0 \\ a(100)\text{ = 6020} \end{gathered}$

Answer:

Step-by-step explanation:

one dollar = $1

2 1/2 = 2.5

$1 / 2.5 = $0.40 or 40 cents

$3.78 / 6 = $0.63 or 63 cents

$1.56 / 20 = $0.078

1 1/2 = 1.5

$1.58 / 1.5 = $1.053

$3.90/5 = $0.79 or 79 cents
