Answer:

y= 4 , x= -1

Step-by-step explanation:

3x-9y= -39

-3x-7y= -25

-16y= -64

y= -64/-16

y= 4

substitute y into any equation

3x -9(4) = -39

3x-36= -39

3x= -39+36

3x= -3

x= -3/3

x= -1

Answer:

Now, as you might recall, two lines are parallel when they are always the same distance apart and never intersect. y= -8 is parallel to y=3 and it passes through the point (-2, -8). The equation of this line is y= -8.

Step-by-step explanation:

In polar form the expression is ( 14 , 30 )

To convert the expression x +iy  to polar form ( r , [tex]\rm \theta[/tex] ) , the standard equations used are

r = [tex]\rm \sqrt {x^2 + y^2}[/tex]

tan [tex]\rm \theta[/tex] = y/x

The given expression is

7 √3 - 7i

x = 7 √3

y = -7

r = [tex]\rm \sqrt {(7\sqrt{3})^2 +(-7)^2}[/tex]

r = √196

r = 14

tan [tex]\rm \theta[/tex] = (-7)/(7√3)

[tex]\rm \theta[/tex] = 30 degree

Therefore in polar form the expression is ( 14 , 30 ).

Answer:

  (x, y, z) = (124, 112, 42)

Step-by-step explanation:

Opposite angles in an inscribed quadrilateral are supplementary, so ...

  y° = 180° -68° = 112°

The angle marked 71° subtends an arc twice that measure, so ...

  2(71°) = 100° +z°

  z° = 142° -100° = 42°

The angle marked y° subtends an arc twice that measure, so ...

  2y° = 100° +x°

  x° = 2(112°) -100° = 124°

Answer:

Step-by-step explanation:

Volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given,

sphere with a diameter of 20 feet

Diameter is two times of radius

Diameter=2Radius

Radius =Diameter/2

Radius = 20/2=10 feet.

Volume of sphere=4/3πr³

π=3.142

Volume of sphere=4/3(3.142)(10)³

=4/3×3.142×1000

=4189.33 cubic feet.

Hence, volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Answer:

£503.75

Step-by-step explanation:

Andy is buying a car.

Step 1

We calculate the decrease

He negotiated a 7% decrease on a £6 500 car.

Decrease = 7% × £6500

= $455

Step 2

We calculate the new price of the car.

= Old price - Decrease

= £6500 - £455

= £6045

Step 3

We calculate the amount he pays every month.

We are told that:

He will pay the full balance in 12 equal monthly payments.

Andy's monthly payments =

New price/12 months

= £6045/12

= £503.75

Therefore, the amount he would be paying each new month = £503.75

Answer:

x × 1/2 - 3

Step-by-step explanation:

in slope intercept form an equation is written in y=mx+b where m is the slope and b is the y intercept

from the graph you can see the line goes up 1 and right 2, up 1 right 2, etc. that means the slope is positive 1/2

the line cross the y access at -3, therefore the y intercept is -3

so

[tex]y = \frac{1}{2} x - 3[/tex]

Answer:

Step-by-step explanation:

Assume that B is directly above A.

x = horizontal distance between Charlie and balloons

 = 1400/tan(60°)

altitude of B = x·tan(82°) ≅ 5751 ft

distance between A and B = 5751-1400 = 4351 ft, which doesn't fit any of the choices. So my initial assumption was incorrect.

Is there any other information? A picture?

The distance between balloon A and balloon B is 1005 feet if Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle option second 1005 feet is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle

In right angle triangle ACD,

tanx = AC/CD

tan60 = 1400/CD

CD = 808.3

In triangle BDE,

tany = BE/DE

tan82 = 1400/DE

DE = 196.8

The distance between balloon A and balloon B:

= CD + DE

= 808.3 + 196.8

=   1005 Feet

Thus, the distance between balloon A and balloon B is 1005 feet if Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle option second 1005 feet is correct.
