Given the equation 2X +4/3 Y equals one and Y -9/13 x=9 by what Vector would you multiply the first equation so that combining t
Mila [183]

Answer: Option B

B. \frac{9}{26}

Step-by-step explanation:

We have the following equations:

2x + \frac{4}{3}y = 1       (1)

y -\frac{9}{13}x=9          (2)

Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.

Then we must multiply the number "a" by a value z such that when adding az + b the result is zero.a = 2

b = -\frac{9}{13}

So

2z-\frac{9}{13} = 0

We solve the equation for z

2z=\frac{9}{13}

z=\frac{9}{26}

The first equation must be multiplied by a value of \frac{9}{26}

which of the following is a true statement a) if AB=CD,then 3CD=3(CD+1). b)if AB=CD,then AB-CD=A-C+B-D. c)if AB=CD,thenAB+EF=CD+
Free_Kalibri [48]

a) if AB = CD, then 3CD = 3(CD + 1) NOT TRUE

example: AB = CD = 1, then 3CD = (3)(1)=3 and 3(CD + 1) = 3(1 + 1) = 3(2) = 6

b) if AB = CD, then AB - CD = A - C + B - D NOT TRUE (it does not make sense because A, B, C and D are points)

c) if AB = CD, then AB + EF = CD + EF TRUE

because

AB = CD    |add EF to both sides

AB + EF = CD + EF

d) if AB = CD, then 2AB = 2A + 2B NOT TRUE (it does not make sense because A and B are points).

Find csc x if sin x + cot x cos x = <img src="https://tex.z-dn.net/?f=%5Csqrt%7B3%7D" id="TexFormula1" title="\sqrt{3}" alt="\sq
GaryK [48]

Answer:

csc(x) = \sqrt{3}

Step-by-step explanation:

sinx + cos^2(x)/sin(x) = sin(x) + (1-sin^2(x))/sin(x)  = 1/sin(x) = csc(x)

csc(x) = \sqrt{3}
