Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

13x - 6y = 22

x = y + 6

Step 2: Solve for y

Substitution

Substitute in x: 13(y + 6) - 6y = 22Distribute 13: 13y + 78 - 6y = 22Combine like terms: 7y + 78 = 22Isolate y term: 7y = -56Isolate y: y = -8

Step 3: Solve for x

Define original equation: x = y + 6Substitute in y: x = -8 + 6Add: x = -2

The slope of the line 5x + y = 15 is___

Answers

Answer:

x = -1/5y +3

Step-by-step explanation:

add -y to both sides

5x + y + -y = 15 + -y

5x = -y + 15

step 2 divide both sides by 5

5x/5 = -y +15/5

x= -1/5 y +3

Answer

x= -1/5 y + 3

Question : If lines BG and CF are parallel, then OLF = OMG. Is this statement correct? Explain your answer.

Answers

Answer:

Yes this statement is correct.

Step-by-step explanation:

just mental math

The statement given that ∠OLF = ∠OMG is found to be; Correct from theorem of corresponding angles.

We are told that;

BC is parallel to CF

Now, we are told that;

∠OLF = ∠OMG

We can see that line DH is a transverse line that crosses the two parallel lines given as BG and CF

Now, according to theorem of corresponding angles, the angle's that are formed when two parallel lines are crossed by a transverse line are said to be equal because they correspond to one another.

In conclusion, it is true from corresponding angles that ∠OLF and ∠OMG are equal.

Find the length of the rectangle if the perimeter is 244 yards the length is 18 less than three times the width?

Answers

Answer:

The Length of rectangle is 87 yards.

Step-by-step explanation:

Let width = w

Length = 3w-18

Perimeter of rectangle = 244 yards

We need to find length of rectangle.

First we need to find value of w

The formula used will be: [tex]Perimeter=2(length+width)[/tex]

Putting values and finding w

[tex]Perimeter=2(length+width)\\244=2(3w-18+w)\\244=2(4w-18)\\244=8w-36\\244+36=8w\\8w=280\\w=\frac{280}{8}\\w=35[/tex]

So, w= 35

The width of rectangle w = 35 yards

The length of rectangle l = 3w-18 = 3(35)-18 = 105-18 = 87 yards.

So, the Length of rectangle is 87 yards.

For f(x) = 5x and g(x)= x + 9, find
(fog)(x); b. (gof)(x); (fog)(3)
a.
C.
a.
(fog)(x)=
(Simplify your answer.)

Answers

Answer:

(fog)(x) = 5x+45(gof)(x) = 5x+9(fog)(3) = f(g(3)) = f(12) = 60

Step-by-step explanation:

Given

f(x) = 5xg(x) = x + 9

Finding (fog)(x)

(fog)(x) = f(g(x))

(fog)(x) = f(x+9)

(fog)(x) = 5(x+9) ∵ substitute x as x+9 in the f(x)

(fog)(x) = 5x+45

Finding (gof)(x)

(gof)(x) = g(f(x))

(gof)(x) = g(5x)

(gof)(x) = 5x+9 ∵ substitute x as 5x in the g(x)

Finding (fog)(3)

(fog)(3) = f(g(3))

substitute x = 3 in the g(x)=x+9

g(x) = x+9

g(3) = 3+9

g(3) = 12

(fog)(3) = f(g(3)) = f(12)

now substitute x = 12 in f(x) = 5x

f(x) = 5x

f(12) = 5(12)

f(12) = 60

Thus,

(fog)(3) = f(g(3)) = f(12) = 60

Emma throws an object upward from a hill that is 64 feet high. The object has an initial velocity of 48 feet per second. The function y = -16x2 + 48x + 64 represents the height of the object, y, in terms of the time elapsed after the object is thrown, x.

Answers

Answer:

100feet

Step-by-step explanation:

Given the height of the object modelled by the equation

y = -16x^2 + 48x + 64

We can find the maximum height reached by the object since we are not told what to find.

The velocity of the object at its max height is zero.

dy/x = 0

dy/dx = -32x + 48

0 = -32x + 48

32x = 48

x = 48/32

x = 1.5secs

get the max height by substituting x = 1.5 into the given equation:

y = -16x^2 + 48x + 64

y = -16(1.5)^2 + 48(1.5)+ 64

y = -36+72+64

y = 100 feet

Hence the maximum height reached by the object is 100feet

The vessel does not halt. The wind blows. That sombre ship has a path which it isforced to pursue. It passes on.The man disappears, then reappears; he plunges, he rises again to the surface; he calls, he stretchesout his arms; he is not heard. The vessel, trembling under the hurricane, is wholly absorbed in its ownworkings; the passengers and sailors do not even see the drowning man; his miserable head is but a speckamid the immensity of the waves. He gives vent to desperate cries from out of the depths. What a spectreis that retreating sail! He gazes and gazes at it frantically. It retreats, it grows dim, it diminishes in size. Hewas there but just now, he was one of the crew, he went and came along the deck with the rest, he had hispart of breath and of sunlight, he was a living man. Now, what has taken place? He has slipped, he hasfallen; all is at an end.He is in the tremendous sea. Under foot he has nothing but what flees and crumbles. The billows, tornand lashed by the wind, encompass him hideously; the tossings of the abyss bear him away; all thetongues of water dash over his head; a populace of waves spits upon him; confused openings half devourhim; every time that he sinks, he catches glimpses of precipices filled with night; frightful and unknownvegetations seize him, knot about his feet, draw him to them; he is conscious that he is becoming an abyss,that he forms part of the foam; the waves toss him from one to another; he drinks in the bitterness; thecowardly ocean attacks him furiously, to drown him; the enormity plays with his agony. It seems asthough all that water were hate.Nevertheless, he struggles.He tries to defend himself; he tries to sustain himself; he makes an effort; he swims. He, his pettystrength all exhausted instantly, combats the inexhaustible.Where, then, is the ship? Yonder. Barely visible in the pale shadows of the horizon.The wind blows in gusts; all the foam overwhelms him. He raises his eyes and beholds only thelividness of the clouds. He witnesses, amid his death-pangs, the immense madness of the sea. He istortured by this madness; he hears noises strange to man, which seem to come from beyond the limits ofthe earth, and from one knows not what frightful region beyond.LES MISRABLES 114There are birds in the clouds, just as there are angels above human distresses; but what can they dofor him? They sing and fly and float, and he, he rattles in the death agony.He feels himself buried in those two infinities, the ocean and the sky, at one and the same time: theone is a tomb; the other is a shroud.Night descends; he has been swimming for hours; his strength is exhausted; that ship, that distantthing in which there were men, has vanished; he is alone in the formidable twilight gulf; he sinks, hestiffens himself, he twists himself; he feels under him the monstrous billows of the invisible; he shouts.There are no more men. Where is God?He shouts. Help! Help! He still shouts on.Nothing on the horizon; nothing in heaven.He implores the expanse, the waves, the seaweed, the reef; they are deaf. He beseeches the tempest;the imperturbable tempest obeys only the infinite.Around him darkness, fog, solitude, the stormy and nonsentient tumult, the undefined curling ofthose wild waters. In him horror and fatigue. Beneath him the depths. Not a point of support. He thinks ofthe gloomy adventures of the corpse in the limitless shadow. The bottomless cold paralyzes him. Hishands contract convulsively; they close, and grasp nothingness. Winds, clouds, whirlwinds, gusts, uselessstars! What is to be done? The desperate man gives up; he is weary, he chooses the alternative of death; heresists not; he lets himself go; he abandons his grip; and then he tosses forevermore in the lugubriousdreary depths of engulfment.Oh, implacable march of human societies! Oh, losses of men and of souls on the way! Ocean intowhich falls all that the law lets slip! Disastrous absence of help! Oh, moral death!The sea is the inexorable social night into which the penal laws fling their condemned. The sea is theimmensity of wretchedness.The soul, going down stream in this gulf, may become a corpse. Who shall resuscitate it?"
