Answer:

A: adjacent angles: The angle ∠CFD & ∠DFE are directly next to each other, making them adjacent angles.

B: Complementary angles: Note that m∠BFC measures at 90°. m∠BFE is a straight line, with 180°. This means that ∠BFE - ∠BFC = ∠DFE.

180 - 90 = 90 ∴ m∠DFE = 90°

What are the coordinates for point A

polet [3.4K]

Answer:

(4, -2)

Step-by-step explanation:

You first go to the x axis (The one going left and round). From this, you can see the point is on 4 for the x axis. After that, you look at the y axis (The one going up and down). From this, you can see it is -2. In all, you put it in coordinate form which gives you (4, -2). I hope this helps you!

G=x-c/x. for x how do yoy make this an equation for x? help

zzz [600]

1.
$\displaystyle \text{if }\quad G=x- \frac{C}{x} \\\\$

$x \neq 0$

Multiply both sides by x:

$\displaystyle Gx=x\bigg(x- \frac{C}{x}\bigg )\\\\Gx=x^2-C$

Subtract from both sides Gx:
$Gx-Gx=x^2-C-Gx\\x^2-Gx-C=0$

Then solve this equation:

$\displaystyle x^2-Gx-C=0\\\\x_{1,2}= \frac{G\pm \sqrt{G^2+4C} }{2}$

2.
$\displaystyle\text{if}\quad G= \frac{x-C}{x}$

$x \neq 0$

Multiply both sides by x:

$Gx=x-C$

Subtract from both sides Gx:

$x-C-Gx=0$

Then solve this equation:

$\displaystyle x-Gx-C=0\\x(1-G)=C\\x= \frac{C}{1-G}$
