Answer:
Not equivalent
Step-by-step explanation:
Distribute the negative in the parentheses. It basically multiplying everything inside by -1.
add like terms
Not equivalent since the 6x is positive

AS PRIME FACTORS OF 90[2&5 didnt get another 2 or 5 to pair up with] CANT FIND A PAIR TO SQUARE THEMSELVES UP, 90 IS NOT A PERFECT SQUARE
Answer: The larger number be 61.
Step-by-step explanation:
Let the second number be 'x'.
Let the first number be 42+x
Average of two numbers = 40
According to question,
So, the larger number of the two numbers i.e the first number is
Hence, the larger number be 61.
Answer:
Slope= -1/3x
Step-by-step explanation:
Answer: The term to term rule is an Arithmetic progression for the two question. B) 1Oth term for the first is 30 and for the second series is 59
Step-by-step explanation:
4.1) 3 6 9 12 15
For the sequence above, we can see that the next term is gotten by addition of 3 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =3
And d common difference =3(6-3,9-6,12-9)
10th term=
T10 = 3+ (10 - 1)3.
T10 = 3+ (9)3.
T10 = 3+ 27.
T10 =30
4.2) 5 11 17 23 29
For the sequence above, we can see that the next term is gotten by addition of 6 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =5
And d common difference =6 (11-5, 17-11,23-17)
10th term=
T10 = 5+ (10 - 1)6.
T10 = 5+ (9)6.
T10 = 5+ 54.
T10 =59
