(a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5
(b) The unit rate is 3.5 cm/s since the rate is constant.
(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.<span />
Answer:
zero solutions
Step-by-step explanation:
46x−23=46x+23
46x - 46x = 23 + 23
0 = 46 (this cannot be a valid solution because 0 is obviously not equal to 46, hence there are no solutions)
Answer:
JN = 32
Step-by-step explanation:
Δ JMN and Δ JKL are similar ( AA postulate )
then the ratios of corresponding sides are in proportion, that is
= 
( substitute values )
= 
= ( cross- multiply )
11 JN = 8(JN + 12)
11 JN = 8 JN + 96 ( subtract 8 JN from both sides )
3 JN = 96 ( divide both sides by 3 )
JN = 32
2 1/7 is a mixed number BUT it is also a rational number.
Turning this into a improper fraction, you'd get 15/7
15/7 = 2.14285...
Repeating decimals are rational numbers
