5)Substituting any of the following equations; i chose bottom into top:
-2x+5=x+2
=>-3x=-3
=>x=1
Sub the x in any of the eqs to find y so
Y=1+2
=>Y=3
ANS: (1,3)
6) substituting the top equation into the bottom one:
3x+2x+4=9
=>5x=13
=>x=13/5 or 2.6
Sub the x in any of the eqs to find the y so
Y=5.2+4
=>y=9.2
ANS: (2.6, 9.2)
Area of the cage : A = L * W
A = 3 * 5
A = 15 sq ft....so ur cage is 15 square ft...and they need at least 12 sq ft...so yes, it is big enough
Area
=3*2/2+6*1/2+3*6/2+(6+7)*6/2
=54
∠M=90°-23.1°=66.9° - it's a right answer.
u=d/sin∠D=97.25
m=cos∠D*u=89.52
63.24 is equivalent to 63.240.
