Step-by-step explanation:

Answer:

x = 7

y = -2

Step-by-step explanation:

Equation 1:  2x + y = 12

Equation 2:  x - y = 9

Rewrite Equation 2 to make x the subject:

⇒ x = 9 + y

Substitute this into Equation 1 and solve for y:

⇒ 2(9 + y) + y = 12

⇒ 18 + 2y + y = 12

⇒ 18 + 3y = 12

⇒ 3y = -6

⇒ y = -2

Substitute found value of y into the rewritten Equation 2 and solve for x:

⇒ x = 9 + (-2)

⇒ x = 7

Step-by-step explanation:

2x + y = 12 equ 1

x - y = 9 equ 2

from equ 2 make x the subject

x - y = 9

x = 9 + y equ 3

substitute equ 3 to equ 1

2x + y = 12

2(9 + y ) + y = 12

18 + 2y + y = 12

3y = - 6

y = -2

substitute y = -2 into equ 3

x = 9 + (-2)

x = 9 - 2 = 7

(x, y) = (7, -2)

let's prove and see if we are correct

2x + y = 12

input the values of (x, y) = ( 7, -2) into the question

2(7) + (-2) = 12

14 - 2 = 12

12 = 12

for the second equation

x - y = 9

Input the values of (x, y) = ( 7, -2) into the question

7 - (-2) = 9

7 + 2 = 9

9 = 9

89 and 41 are acute

1 is also wrong

Answer:

  7.  B 2·2·3·a

  9.  B 41°

Step-by-step explanation:

You want the greatest common factor of 24a² and 36ab, and you want the smallest integer-valued angle in an acute triangle with one angle 50 degrees.

The factors of 24a² are 2·2·2·3·a·a.

The factors of 36ab are 2·2·3·3·a·b.

The factors these lists have in common are 2·2·3·a, matching choice B.

If one angle of a triangle is 50°, the sum of the other two angles must be ...

  180° -50° = 130° . . . . . . sum of angles B and C

One of these angles will be the smallest it can be only if the other is the largest it can be. The largest integer acute angle is 89°, so the smaller angle will be ...

  130° -89° = 41°

The smallest possible angle in the acute triangle is 41°.

Answer:

x^3+5x^2+16x+80

Step-by-step explanation:

You know that you can write your polynom this way : (x-r1)(x-r2)(x-r3) with r1,r2 and r3 the roots so you get :

(x+5)(x+4i)(x-4i)

Simplify (x+4i)(x-4i) with the formula (a-b)(a+b)=a²-b²

so you have (x^2+16)=(x+4i)(x-4i)

Your polynom looks like this :

(x^2+16)(x+5) just expand it

and you get x^3+5x^2+16x+80

Answer:

As Per Provided Information

Answer:

[tex]y = 5[/tex]

Step-by-step explanation:

Given function:

[tex]y=\dfrac{5x}{x+6}[/tex]

[tex]\implies y=5 \left( \dfrac{x}{x+6}\right)[/tex]

[tex]\textsf{As }x \rightarrow +\infty, \ \dfrac{x}{x+6} \rightarrow1[/tex]  

[tex]\implies y\rightarrow5[/tex]

[tex]\textsf{As }x \rightarrow -\infty, \ \dfrac{x}{x+6} \rightarrow1[/tex]  

[tex]\implies y\rightarrow5[/tex]

As [tex]x[/tex] approaches infinity and negative infinity, [tex]y[/tex] approaches 5 (but never gets there).    Therefore, the horizontal asymptote is [tex]y=5[/tex]

Answer:

(a) BC = 91 cm

(b) ∠C = 33.4° (nearest tenth)

(c) AD = 79.5 cm (nearest tenth)

Step-by-step explanation:

(a) Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

⇒ 60² + BC² = 109²

⇒ 3600 + BC² = 11881

⇒ BC² = 11881 - 3600

⇒ BC² = 8281

⇒ BC = √(8281)

⇒ BC = 91 cm

(b) Sine rule to find an angle:

   [tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles, and a, b and c are the sides opposite the angles)

Given:

[tex]\implies \dfrac{\sin (90)}{109}=\dfrac{\sin C}{60}[/tex]

[tex]\implies \sin C=60 \cdot\dfrac{\sin (90)}{109}[/tex]

[tex]\implies \sin C=\dfrac{60}{109}[/tex]

[tex]\implies C=33.39848847...\textdegree[/tex]

[tex]\implies C=33.4\textdegree \ \sf(nearest \ tenth)[/tex]

(c) Sine rule to find a side length:

   [tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

(where A, B and C are the angles, and a, b and c are the sides opposite the angles)

Sum of interior angles of a triangle = 180°

Given:

[tex]\implies \dfrac{AD}{\sin (90)}=\dfrac{60}{\sin (49)}[/tex]

[tex]\implies AD=\sin (90) \cdot \dfrac{60}{\sin (49)}[/tex]

[tex]\implies AD=79.5007796...[/tex]

[tex]\implies AD=79.5 \ \sf cm \ (nearest \ tenth)[/tex]

Answer:

The standard form of the equation of the ellipse is x² + y²/36 = 1

Step-by-step explanation:

* Lets revise the standard equation of the ellipse

- The standard form of the equation of an ellipse with  

 center (0 , 0) is  x²/b² + y²/a² = 1

where,

* the length of the major axis is 2a

* the coordinates of the vertices are (0 , ±a)

* the length of the minor axis is 2b

* the coordinates of the co-vertices are (±b , 0)

*  the coordinates of the foci are (0 , ± c),  where c² = a² - b²

* Now lets solve the problem

∵ The vertex of the ellipse is (0 , 6)

∴ a = 6

∵ The co-vertex is (1 , 0)

∴ b = 1

∵ the center is the origin (0 , 0)

∵ The standard form equation is x²/b² + y²/a² = 1

∴ x²/(1)² + y²/(6)² = 1 ⇒ simplify

∴ x² + y²/36 = 1

* The standard form of the equation of the ellipse is x² + y²/36 = 1

Answer:

(-2,-3)

Step-by-step explanation:

Put the equations over each other.

[tex] \binom{x - y = 1}{ - x + 3y = - 7 } [/tex]

Subtract the x values.

[tex] \binom{ - y = 1}{3y = - 7} [/tex]

Subtract on both sides.

[tex]2y = - 6[/tex]

Divide on both sides.

[tex]y = - 3[/tex]

Insert the y value into one of the equations.

[tex]x - ( - 3) = 1[/tex]

Get rid of the parenthesis.

[tex]x + 3 = 1[/tex]

Subtract on both sides.

[tex]x = - 2[/tex]

You could also individually plug in each solution into both equations to see if they are true.

2010

Step-by-step explanation:

volume of a cube= hxlxw

5x5x5=125

V=πr2h

π10^2x6=1884.9=1885

1885+125=2010

Answer:

the area for

a=16pi or 50.26548...

b=64pi or 201.061329...

c= 169pi or 530.929158...

d=100pi or 314.159265

d is 19.7392088... or 6.25pi times greater than a

Step-by-step explanation:

the decimal values are more accurate for the d is greater than circle a

so you start with a=4 in radius then b=a+4, c=b+5, d=c-3

then solve the equation a=4, b=8, c=13, d=10

then you solve for the area using the formula radius squared pi

getting the answers above

as for the second answer you would divide d to a getting the amount of times more above for circle d and circle a
