Answer:
<em>ab+bc+ca=0</em>
Step-by-step explanation:
We are given:
xyz=1
Separating equations:
Solving the first equation for x:
Solving the second equation for y:
Substituting in
xyz=1:
Adding the exponents:
Since :
The base is z on both sides so we get rid of them:
Multiplying by ab:
bc+ac+ab=0
Reordering:
ab+bc+ca=0
8 if not that then its 56 or i might be wrong but it seems right to me
Answer:
The answer is 21/40
Step-by-step explanation:
(1×5)+(2×8)8×5
=5+16/40
=21/40
Have a blessed day :)
(4x + 2)(4x - 2) = 16x^2 - 8x + 8x - 4
Combine like terms 16x^2 - 4
Explanation
Just multiply the each term in the first parentheses by the other terms in the second parentheses.
Answer:
-2x+y+4<0
Step-by-step explanation:
y=mx+b
(m) slope is 2 (4/2)
(b) intercept is -4
y=2x-4
-2x+y+4=0
Plug in the origin for x and y (0,0)
4=0
since we do not want the side of the graph shaded to include the origin, the sign needs to be <
-2x+y+4<0
