Answer:
According the the Property of Equality (POE), if a=b and b=c, then a=c.
If -8y + 8 = x and x = -2y + 2, substitute so that it becomes -8y + 8 = -2y + 2.
Solve from there:
Move the y variables to their own side.
-8y + 2y = 2-8
-6y = -6
y = -6
Then plug the y into either equation to find x.
x = -2y + 2
x = -2(-6) + 2
x = 12 + 2
x = 14

Yes it is true
When we do the sum with the value as x -27 then we will get the answer

Answer:
The cross product is 47 i - 61 j + 17 k.
Step-by-step explanation:
Given that-
a = < -1, -3, -8 > , b = < 7, 4, -5 >
The cross product is
a × b =\begin{gathered}\left[\begin{array}{ccc}i&j&k\\-1&-3&-8\\7&4&-5\end{array}\right]\end{gathered}⎣⎢⎡i−17j−34k−8−5⎦⎥⎤
= i ( - 3 × -5 - 4 × -8 ) - j ( -1 × -5 - (-8) × 7 ) + k ( -1 × 4 - 7 × -3 )
= i ( 15 + 32 ) -j ×( 5 + 56 ) + k ( -4 + 21 )
= i ( 47) - j (61 ) + k (17)
= 47 i -61 j + 17 k
As we know that if two vectors A & B are perpendicular then
A . B = 0
So here only the given vector b = < 7,4, -5> is perpendicular to the resulting vector .
