Write the first five terms of the arithmetic sequence. a4 = 22, a10 = 64

dedylja [7]

Hello :
the general term is :
an = a1+(n-1)×d
or : an = ap +(n-p)×d......d is common diffrence
let : n=10 and p= 4
a10 = a4 +(10-4)×d
64 = 22 + 6d
6d = 42
d= 7
conclusion :
a4 = 22
a3 = 22-7=15
a2=15-7=8
a1= 8-7=1
<span>the first five terms : 1 , 8 , 15 , 22</span>

What is the inverse of the function f(x) = 2x – 10?

Lana71 [14]

Answer:

$h(x)=\dfrac{x}{2}+5$

Step-by-step explanation:

You are given the function $f(x)=2x-10$ . To find the inverse function $f^{-1}(x)$ do such steps:

1. Rewrite the function f(x) as

$y=2x-10$

2. Express x in terms of y:

$y+10=2x\\ \\x=\dfrac{y}{2}+5$

3. Change x into y and y into x:

$y=\dfrac{x}{2}+5$

Now, the inverse function is

$f^{-1}(x)=\dfrac{x}{2}+5$

Solve 1/3x - 5/6x =1/4

Harrizon [31]

Answer:

-1/2

Step-by-step explanation:

Given:

$\frac{1}{3}x - \frac{5}{6} x = \frac{1}{4}$

Find the common denominator for the fractions, which is 6. Rewrite 1/3 as 2/6.

$\frac{2}{6}x - \frac{5}{6} x = \frac{1}{4}$

Combine like terms.

$-\frac{3}{6} x = \frac{1}{4}$

Simplify.

-0.5x = 1/4

Divide both sides by -0.5.

x = -1/2 = -0.5
