1)
||x|-4|= |x-1|
1st step = separate the equation into 2 possible equations
2nd step = solve the equations
|x|-4= x-1
x= -3/2
Or
|x|-4= - (x-1)
X= 5/2

2)

Do the same
X= -5/2
X= 7/2

A radio telescope array is in an unpopulated desert region. The array covers a rectangular area that is one fourth square kilome

kramer

Answer:

3 km

Step-by-step explanation:

The area of a rectangle is given by the formula ...

A = LW

Filling in the given information, we can solve for the length.

1/4 = L·(1/12)

Multiplying by 12, we see that ...

3 = L

The array is 3 kilometers long.

I really need some help. I need to find the inverse of this equation in the picture below. Thanks!

serg [7]

Answer:

y=81x^4+648x^3+1944x^2+2592x+1289

Step-by-step explanation:

1. Interchange x and y.

y=\frac{\sqrt[4]{x+7}}{3}-2

x=\frac{\sqrt[4]{y+7}}{3}-2

2. Then solve x=\frac{\sqrt[4]{y+7}}{3}-2 for y.

3. y=81x^4+648x^3+1944x^2+2592x+1289

I hope this helps.

What is the value of x?

Talja [164]

Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

$a^{2} + b^{2} = c^{2}$

Plug in the known values into the equation:

$a = 6, c = 10$

$6^{2} + b^{2} = 10^{2}$

$36 + b^{2} = 100$

Subtract both sides by 36.

$b^{2} = 64$

Square root both sides to get b by itself.

$\sqrt{64} = 8$

$b = 8$

The value of x is 8.
