Explanation: The 4th one is the distributive property because it shows an equal sign and the 5th one is the inverse property of addition because it uses more than addition.
Answer: 4th one is distributive property 5th one is inverse property of addition
P.S. I am sure 95% sure that I am correct.
GIVEN :
a = 1/√10 ( 3i + k) and
b = 1/7 ( 2i + 3j - 6k)
TO FIND :
( 2a- b) . [ ( a x b ) x ( a + 2b)]
SOLUTION :
◆Going with the equation given,
( 2a - b) . [ ( a x b ) x ( a + 2b)]
= (2a - b) [( a×b×a) + 2(a×b)×b]
◆BAC - CAB RULE,
A×B×C = B( A.B ) - C(A.B )
= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]
Solving further
= (2a - b )(b - 2a)
= -4a.a -b.b
=-5.
Answer:
( 2 - b) . [ ( a x b ) x ( a + 2b)] = -5

Answer:
y +5 = (-2/3)(x -4)
Step-by-step explanation:
The point-slope form of an equation of a line with slope m through point (h, k) is ...
... y -k = m(x -h)
You have (h, k) = (4, -5) and a slope the same as that of the parallel line, m = -2/3. Then the equation is ...
... y -(-5) = (-2/3)(x -4)
... y +5 = (-2/3)(x -4)
Answer:
5.) 0.134 kg.
6.) 6.15 km.
7.) 5.9 kg.
Step-by-step explanation:
5.) 0.37 - 0.236 = 0.134
6.) 9.71 - 3.56 = 6.15
7.) 1.7 + 4.2 = 5.9
Answer:
$1.80 is the cost for 3/4 of a pound of apples. If you divide 1.5 over 2, it would be 3/4, which means you will divide the price too, 3.60/2 = $1.80
