It's not necessary that either one represents a proportional
relationship. But if either one does, then the other one doesn't.
They can't both represent such a relationship.
The graph of a proportional relationship must go through
the origin. If one of a pair of parallel lines goes through
the origin, then the other one doesn't. (If two parallel lines
both went through the origin, then they would both be the
same line.)
Answer:
the number is 10
Step-by-step explanation:
3x + 10 = 6x-20
20+10=6x-3x
30=3x
x=10
L*W*H , So 4*4*4, So therefore it would be 64 m3
Answer:
70.4 meters
Step-by-step explanation:
A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23
B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15
41.23+29.15=70.38
The right chose is -9x+3= the others are not hope this helped
