Step-by-step explanation:
let Sean be 4 years old and Rachel be 2 years old on April 17
part (A)
R=S-2 --(A)
is an equation that can be used to determine Rachel's age
likewise,
S=R+2--(B)
can be used to determine Sean's age
part (B)
use equation(A) for table (1) and equation(B) for table 2
Table (1) : R=S-2=11-2= R=9
12-2=10=»R=10
13-2=11=»R=11
14-2=12=»R=12
15-2=13=»R=13
16-2=15=»R=14
likewise use equation B for the table (2)
the outputs must be 3,4,5,6,7,8
and 9
Answer:
(x+3)(x-3) is x²-9
Step-by-step explanation:
The answer is to this question is -1/20
We cannot simplify it because the denominator does not have a common factor with the numarator.
Answer:
Is there a x somewhere or is that litteraly how the equation is?
If so, -7 multiplied by 2 is -14,
-1 times -7 is 7,
add it together and you get
-7=28,
you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0
which would make the solution false since both sides are not the same
