Hey guys me anyone i mean anyone whoo explains well and not for the points will be marked as brainliest .solve each system by substitution so we have -4x+6y=12
x+2y=-10 so far i got -14y=52 dont get me wong i know how to solve it but since 14 goes into 52 3 times do i then have to plug in for y

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
