Answer:

x,y =2,1

Step-by-step explanation:

3x+4y=10          ................equ1

x-y=1                 ................equ2

This system of equations forms a quadratic equation.

Lets use the substitution method in solving this set of equations

from equ 2;  x=y+1

substitute x=y+1 into equ 1

3(y+1) +4y=10

3y+3+4y=10

7y=10-3

7y=7

y=7/7

y=1

but x=y+1

substitute the value of y into this equation to get x

x= 1+1

x=2

x,y=2,1

What is the measure of the arc from A to B that does not pass through C?
sergeinik [125]

Applying the inscribed angle theorem, the measure of the arc from A to B is: 100 degrees.

<h3>What is the Inscribed Angle Theorem?</h3>

The inscribed angle theorem states that an inscribed angle in a circle is half the central angle.

Angle BAC = 40 degrees, so, central angle = 80 degrees. Arc BC would also be 80 degrees.

Measure of arc AC through point B = 180 degrees.

Arc AB = 180 - 80 = 100 degrees.

10x - 12y = 22<br> 5x - 6y = 11 elimanation
lawyer [7]

Answer:

This is an identity or infinite solutions

Step-by-step explanation:

10x - 12y = 22

5x - 6y = 11

-2(5x - 6y = 11 )

-10x + 12y = -22

10x - 12y = 22

0=0

Options: <br> y= -2x - 6<br> y= 2/3x + 6<br> y= -2/3x + 6<br> y=2x + 6
melisa1 [442]

Answer:

y = - \frac{2}{3} x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 2) ← 2 points on the line

m = \frac{2-6}{6-0} = \frac{-4}{6} = - \frac{2}{3}

The line crosses the y- axis at (0, 6) ⇒ c = 6

y = - \frac{2}{3} x + 6 ← equation of line
