Answer: 7
Step-by-step explanation:
2−(−4)+3+(−6)−(−2)2
solution:
– x – = +
– x + = –
= 2−(−4)+3+(−6)−(−2)2
= 6 + 3 + ( – 6) – ( 2 ) 2
= 9 + ( –6 ) – ( –2 ) 2
= 3 – (–2)2
= 3 – ( –4 )
= 7
Answer: Which statement is False
Step-by-step explanation:
proportional relationships
y ∝ x
=> y = kx
Comparing with line line of equation
y = mx + c
m = k , c = 0
Hence A proportional relationship must graph as a line
TRUE
at x = 0 , y = 0
Hence graph of a proportional relationship must pass through (0, 0).
TRUE
y = kx
=> y/x = k hence
Each point (or pair) in a proportional relationship must share the same ratio.
TRUE
Each point (or pair) in a proportional relationship must share the same difference.
FALSE
70 + 78 + 91 = 239
239 - 42 - 36 = 161
