A pair of equations is shown below.3x − y = 9
y = −2x + 11

If the two equations are graphed, at what point do the lines representing the two equations intersect?
(4, 3)
(3, 4)
(9, 11)
(11, 9)

Answers

Answer:

Hence, the two equations intersect at:

(4,3)

Step-by-step explanation:

We are given:

A pair of equations:

3x − y = 9

y = −2x + 11

now, on graphing these equations.

as we can clearly see from the graph the two lines intersect at (4,3)

Hence, the two equations intersect at:

(4,3)

3x − y = 9
y = −2x + 11

3x − (−2x + 11) = 9
3x + 2x - 11 = 9
5x = 9 + 11
5x = 20
x = 4

y = −2x + 11 = -2*4+11 = 3

(4, 3)

What are the coordinates of the y-intercept of the line whose equation is LaTeX: 12x+13y=812 x + 13 y = 8? ( , )

Answers

The coordinates of the y-intercept of the line whose equation is

12 x + 13 y = 8 is 8/13.

As given in the question,

Given equation: 12x + 13 y=8

Convert the equation into y-intercept form

General form of y-intercept form is

y=mx + b

Subtract from the equation 12x from both the side of equation,

12x+13y-12x=-12x+8

⇒ 13y=-12x +8

Divide both the side by 13

13y/13= (-12/13)x +8/13

⇒y=(-12/13)x +8/13

To get y-intercept put x=0

y =8/13

Therefore, thecoordinates of the y-intercept of the line whose equation is 12 x + 13 y = 8 is 8/13.

The complete question is :

Points B and C lie on a circle with center O and radius r = 5 units. If the length of BC is 10.91 units, what is m∠BOC in radians? Use the value π = 3.1416, and round your answer to three decimal places.

Answers

Seems to me that the situation described is impossible.

If the circle's radius is 5, then its diameter is 10. The diameter of the circle
is the farthest apart that two points on the circle can be. So points 'B' and 'C'
can not be 10.91 apart.

==========================

Oh ! But wait. I gues you mean the distance between them along the circle.
(You just said "the length of BC", which usually means the straight-line distance.)

OK.
The piece of the circumference that's 10.91 long is (10.91/5) radiuses long.
So the central angle that encloses it is (10.91/5) = 2.182 radians.

Answer:

m∠BOC=2.182 radians

Step-by-step explanation:

It is given that Points B and C lie on a circle with center O and radius r = 5 units, length of BC=10.91 units, then using the formula,

$S=r{\theta}$ where S is the arc length, r is the radius and ${\theta}$ is in radians, thus
