If a solution(s) exists y=y so we can say:

x^2-3x=-2x+2 add 2x to both sides

x^2-x=2 subtract 2 from both sides

x^2-x-2=0 factor

(x-2)(x+1)=0

So x=-1 and 2, using y=-2x+2 we find:

y(-1)=4 and y(2)=-2

So the two solutions occur at the points:

(-1,4) and (2,-2)

Simplify 13 over the quantity of negative 3 plus 2i.

jasenka [17]

$\frac{13}{(-3+2i)}$

To simplify we need to rationalize it. which can be done by multiplying composite of denominator. That is multiply by -3-2i

$=\frac{13}{(-3+2i)}*\frac{(-3-2i)}{(-3-2i)}$

Now multiply numerator with numerator and denominator with denominator

$=\frac{(-39-26i)}{(-3)^2-(-2i)^2}$

$=\frac{(-39-26i)}{9-(4i^2)}$

$=\frac{(-39-26i)}{9-(4(-1))}$

$=\frac{(-39-26i)}{9-(-4)}$

$=\frac{(-39-26i)}{9+4}$

$=\frac{(-39-26i)}{13}$

$=-3-2i$

Hence final answer is $=-3-2i$

Find the value of x

Mumz [18]

Answer:

See Explanation

Step-by-step explanation:

The measure of angle X would be 50 degrees because 65 degrees is already labeled and B would also be 65 degrees so 65 + 65 = 130, and finally subtract 180 - 130 to get the final measure of angle X: 50 degrees
