Answer:
Scale= 3 x=9 y=15
Step-by-step explanation:
Answer:
variable is (<em> </em><em>x</em><em> </em><em>)</em>
<em>∆</em><em>product</em><em> </em><em>of</em><em> </em><em>8</em><em> </em><em>:</em>
<em>8</em><em> </em><em>x</em>
<em>∆</em><em>the</em><em> </em><em>number</em><em> </em><em>increase</em><em>d</em><em> </em><em>by</em><em> </em><em>2</em><em> </em><em>:</em><em> </em>
<em>8</em><em> </em><em>x</em><em> </em><em>+</em><em> </em><em>2</em>
<em>And</em><em> </em><em>we</em><em>'re</em><em> </em><em>done</em><em> </em><em>♥️</em>

A negative number is always less than a positive.
Direction vector of line of intersection of two planes is the cross product of the normal vectors of the planes, namely
p1: x+y+z=2
p2: x+7y+7z=2
and the corresponding normal vectors are: (equiv. to coeff. of the plane)
n1:<1,1,1>
n2:<1,7,7>
The cross product n1 x n2
vl=
i j l
1 1 1
1 7 7
=<7-7, 1-7, 7-1>
=<0,-6,6>
Simplify by reducing length by a factor of 6
vl=<0,-1,1>
By observing the equations of the two planes, we see that (2,0,0) is a point on the intersection, because this points satisfies both plane equations.
Thus the parametric equation of the line is
L: (2,0,0)+t(0,-1,1)
or
L: x=2, y=-t, z=t
Pretty sure its 36 (not sure) i keep getting 36.6 cm
