Answer:

$g(x) - f(x) = x^{2} - 2x - 4$

Step-by-step explanation:

g(x) - f(x) = $(x^{2} + 1) - (2x + 5)$

<em><u>Multiply the -1 in then add the two expressions together.</u></em>

$(x^{2} + 1) + (-2x - 5) = x^{2} - 2x - 4$

Which of the following best describes the folding method needed to create a

vivado [14]

Fold tracing paper so that the line segment's endpoints line up with each other , Option D is the correct answer.

<h3>What is a Perpendicular ?</h3>

A perpendicular is a line drawn at 90 degree to a given line or line segment .

Fold tracing paper so that the line segment's endpoints line up with each other.

After drawing a line segment ,

when the end point will be on each other and a crease will be made by pressing the paper , The crease formed will be perpendicular to the line segment.

Therefore, Option D is the correct answer.

If J is the centroid of cde, de=52, fc=15, he=14, find each missing measure

const2013 [10]

Answer:

$DG = 26$

$GE = 26$

$DF = 15$

$CH = 14$

$CE = 28$

Step-by-step explanation:

The figure has been attached, to complement the question.

$DE = 52$

$FC = 15$

$HE = 14$

Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:

$DF = FC$

$CH = HE$

$DG = GE$

Solving (a): DG

If $DG = GE$ , then

$DE = DG + GE$

$DE = DG + DG$

$DE = 2DG$

Make DG the subject

$DG = \frac{1}{2}DE$

Substitute 52 for DE

$DG = \frac{1}{2} * 52$

$DG = 26$

Solving (b): GE

If $DG = GE$ , then

$GE = DG$

$GE = 26$

Solving (c): DF

$DF = FC$

So:

$DF = 15$

Solving (d): CH

$CH = HE$

$CH = 14$

Solving (e): CE

If $CH = HE$ , then

$CE = CH + HE$

$CE = 14 + 14$

$CE = 28$

What is a reflexive angle?

zalisa [80]

Is the larger angle. It is more than 180° but less than 360° If you choose the smaller angle you might have an Acute Angle, or an Obtuse Angle instead: The larger angle is a Reflex Angle, but the smaller angle is an Acute Angle.

What is an equation of the line that passes through the point (-3,-1) and is

Yuri [45]

Answer:

y = -2x - 7

Step-by-step explanation:

x - 2y = 6

-2y = -x + 6

Divide the whole equation by (-2)

$\frac{-2y}{-2}=\frac{-x}{-2}+\frac{6}{-2}\\\\y = \frac{1}{2}x - 3$

slope = 1/2

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

$=(-1)*\frac{2}{1}\\\\= -2$

(-3, - 1)

y -y1 = m(x -x1)

y - [-1] = -2(x - [-3])

y + 1 = -2(x + 3)

y + 1= x* (-2) + 3*(-2)

y + 1 = -2x - 6

y = -2x - 6 - 1

y = -2x - 7
