<u>Given </u><u>:</u><u>-</u><u> </u>

  • A equation 6x - 3 = Ax - 3 - 2x

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of A so that the equation has infinitely many solutions .

<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>

Given equation ,

  • 6x - 3 = Ax - 3 - 2x .

Add 3 to both sides ,

  • 6x = Ax - 2x

Add 2x to both sides ,

  • 6x + 2x = Ax

Simplify ,

  • 8x = Ax

Divide both sides by A .

  • A = 8

<u>Hence</u><u> the</u><u> </u><u>value</u><u> </u><u>of </u><u>A </u><u>should</u><u> be</u><u> </u><u>8</u><u> </u><u>.</u>

Answer:

4th option

Step-by-step explanation:

6x-3= Ax-3-2x

Marianna [84]

Answer:

step number 1 is incorrect.

Step-by-step explanation:

Here is the solution of this equation [2x-31-1=2].

2x-31-1=2

or 2x-31=2+1

or 2x=2+1+31

or 2x= 34

or x=34/2

or x= 17

the answer of this equation is X=17.

What is the value of the function at x=−3?<br><br> A) y = 0<br> B) y=−3<br> C) y = 4<br> D) y = 3
Alexus [3.1K]

Answer:

y=4

Step-by-step explanation:

From the graph we can see that-

when, x=-3 ,  y=4

That is , the graph passes through   (-3 , 4)

So,

for  x=-3 ,

we get    y=4

So, the answer is    y=4

The hyperbolic orbit of a comet is represented on a coordinate plane with center at (0, 4). One branch has a vertex at (0, 10) a
Anuta_ua [19.1K]

Remember that

If the given coordinates of the vertices and foci have the form (0,10) and (0,14)

then

the transverse axis is the y-axis

so

the equation is of the form

(y-k)^2/a^2-(x-h)^2/b^2=1

In this problem

center (h,k) is equal to (0,4)

(0,a-k)) is equal to (0,10)

a=10-4=6

(0,c-k) is equal to (0,14)

c=14-4=10

Find out the value of b

b^2=c^2-a^2

b^2=10^2-6^2

b^2=64

therefore

the equation is equal to

<h2>(y-4)^2/36-x^2/64=1</h2><h2>the answer is option A</h2>

Solve the differential equation using the method of undetermined coefficients
yuradex [85]
First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)

next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
