spayn [35]

Answer:

QS=12, QT=21

Step-by-step explanation:

QS=RT

5x+17=10-2x

x= -1

QS= 12

QS-RS=QR

QR=ST=9

QS+ST=QT

QT=22

13. Find the equation of the line through the points (3, -1) and (6, 7).
erik [133]

Ans:8x-3y=27

Step-by-step explanation:

let,A,B be the line which have points (3,-1),(6,7)

here,

(3,-1)=(x1,y1)

(6,7)=(x2,y2)

then,

slope of line AB =(y2-y1/x2-x1)

=(7+1/6-3)

=8/3

Now,

equation of the line AB,

(y-y1)=m(x-x1)

(y+1)=8/3(x-3)

3y+3=8x-24

-8x+3y=-24-3

-8x+3y=-27

-(8x-3y=27)

8x-3y=27

Hence, the equation of the line through the points (3,-1) ,(6,7) is 8x-3y=27.

write an equation of the perpendicular bisector of the line segment whose endpoints are (-1,1) and (7,-5)
RUDIKE [14]
m = \frac{y_{2} - y_{1}}{c_{2} - x_{1}} = \frac{-5 - 1}{7 - (-1)} = \frac{-6}{7 + 1} = \frac{-6}{8} = \frac{-3}{4} = -\frac{3}{4}

y - y₁ = m(x - x₁)
 y - 1 = ⁻³/₄[x - (-1)]
 y - 1 = ⁻³/₄(x + 1)
 y - 1 = ⁻³/₄(x) - ³/₄(1)
 y - 1 = ⁻³/₄x - ³/₄
    +1          + 1
      y = ⁻³/₄x + ¹/₄
