Hi there!

»»————-　★　————-««

I believe your answer is:

$x = \frac{1}{4}$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving the equation for x...}}\\\\4x + 54 = 55\\----------\\\rightarrow 4x + 54 - 54 = 55 - 54\\\\\rightarrow 4x = 1\\\\\rightarrow \frac{4x=1}{4}\\\\\rightarrow \boxed{x=\frac{1}{4}}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Let F be a field, and suppose a EF, a *0. Prove that a has a unique multiplicative inverse.

bezimeni [28]

Answer with Step-by-step explanation:

Let F be a field .Suppose $a\in F$ and $a\neq 0$

We have to prove that a has unique multiplicative inverse.

Suppose a has two inverses b and c

Then, $ac=1,ab=1$ where 1 =Multiplicative identity

$ac=ab$

$c=b$ (cancel a on both sides)

Hence, a has unique multiplicative inverse.

Look at the graph of this system of equations: y=-x^2+1 and y=x^2. At which approximate points are the two equations equal?

djyliett [7]

Answer:

x = 0.7071

y = 0.5

Step-by-step explanation:

y=-x^2+1

y=x^2

then:

-x^2+1 = x^2

2x^2 = 1

x^2 = 0.5

x = 0.7071

y = 0.5
