Answer:X1=1+-1+i(2)^1/2

x2=-1-i(2)^1/2

Step-by-step explanation

y=y

-2x+1=-x^2+4

x^2+4+2x-1=0

x^2+2x+3=0

Use

Ax^2+Bx+C=0

X1,X2=[-B+(B^2-4*A*C)^1/2]/2*A

A=1

B=2

C=3

x=[-2+/-(2*2-12)^1/2]/2

x=[-2+/-(-8`)^1/2]/2

x=[-2+/-2i(2)^1/2]/2

x1=-1+i(2)^1/2

x2=-1-i(2)^1/2

Answer:

$\boxed{\frac{-3b^4 }{a^6 }}$

Step-by-step explanation:

$\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}$

$\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

$-3 \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

$-3 \times a^{-8-(-2)} \times b^{-3- (-7)}$

$-3 \times a^{-8+2} \times b^{-3+7}$

$-3 \times a^{-6} \times b^{4}$

${-3a^{-6}b^{4}}$

The answer should be without negative exponents.

$a^{-6}=\frac{1}{a^6 }$

$\frac{-3b^4 }{a^6 }$

4x - 3y= 20 <br> Solve for y plz show work plz

emmasim [6.3K]

Answer:

Simplifying
4x + -3y = 20

Solving
4x + -3y = 20

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.
4x + -3y + 3y = 20 + 3y

Combine like terms: -3y + 3y = 0
4x + 0 = 20 + 3y
4x = 20 + 3y

Divide each side by '4'.
x = 5 + 0.75y

Simplifying
x = 5 + 0.75y

Someone please help! You have to show your work.

40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
