-4x+5y=17 4x+6y=-6 solve using elimination<br><br>SHOW WORK
Ber [7]

-4x+4x +5y +6y = 17-6

11y=11

divide both side by 11 to isolate y

y=1

4x+6(1) = -6

subtract 6 on both sides

4x=-12

divide 4 on both sides

x=-3

Drag the tiles to the correct boxes to complete the pairs.
olchik [2.2K]

Answer:

1)(2m^2-4m)/2(m-2) = m (fourth blank)

2)m^2-2m+1/m-1= m-1 (second blank)

3)m^2-3m+2/m^2-m= (m-2)/m (first blank)

4)m^2-m-2/m^2-1=(m-2)/(m-1)    (third blank)

Step-by-step explanation:

1)

(2m^2-4m)/2(m-2)

=[2m(m-2m)]/2(m-2)

= 2m/2

=m

2)

m^2-2m+1/m-1

= (m-1)^2/(m-1)

=(m-1)(m-1)/(m-1)

=(m-1)

3)

m^2-3m+2/m^2-m

=m^2-m-2m+2/m(m-1)

=m(m-1)-2(m-1)/m(m-1)

= (m-1)(m-2)/m(m-1)

=(m-2)/m

4)

m^2-m-2/m^2-1

=m^2+m-2m-2/(m+1)(m-1)

=m(m+1)-2(m+1)/(m+1)(m-1)

=(m+1)(m-2)/m+1)(m-1)

=(m-2)/(m-1) !

Need help pls on circle geometry
Katyanochek1 [597]

Answer:

25

Step-by-step explanation:

AB is a tangent to the circle hence the angle ABO is a right angle !!! With that knowledge we can construct a right-angled triangle with sides AB ,BO and OA .

Applying the Pythagorean theorem we get that OA is the hypotenuse and thus

oa =    \sqrt{ab {}^{2} + ob {}^{2}  }
