2x - y = -10
y = 4x
2x - 4x = -10
-2x = -10
x = 5

y = 4x
y = 4* 5
y = 20

Answer : (x,y) = (5,20)

Solve the equation Square root of x minus 5+ 7 = 11 for the variable. Show each step of your solution process. (10 points)

Murrr4er [49]

$\sqrt{x - 5} + 7 = 11$

$(\sqrt{x-5}) ^{2} = (4)^{2}$

|x - 5| = 16

x - 5 = +/- 16

x - 5 = 16 or x - 5 = -16

+5 +5 +5 +5

x = 21 or x = -11

Answer: x = {21, -11}

What is the arithmetic rule to the sequence: 1/3,4/3,7/3 find: f(10)

makkiz [27]

The the value of f(n)= $\frac{28}{3}$

Step-by-step explanation:

The Arithemetic sequence is given as a,a+d,a+2d......a(n-1)d

and f(n)=a(n-1)d

The given sequence is 1/3,4/3,7/3...

By comapring with Arithemetic sequence,

we get a=1/3

a+d=4/3

1/3 + d = 4/3

d=1

To find value of f(10):

take n=10

f(n)= $\frac{1}{3} +(10-1)1$

f(n)= $\frac{1}{3} +(9)1$

f(n)= $\frac{1+27}{3}$

f(n)= $\frac{28}{3}$
