Malik asked his teacher if there was a way to check his answer after writing equivalent expressions. what should be his teacher’s response? -choose a number to substitute for the variable. find the value of each expression. if the values are even, the expressions are equivalent. -substitute a number for the variable. if the simplified expressions have the same value, the expressions are equivalent. -multiply each expression by the same number. if the expressions are equal, the expressions are equivalent. -add a number to each expression. if the simplified expressions are equal, the expressions are equivalent.

Substitute a number for the variable. If the simplified expressions have the same value, the expressions are equivalent.

Step-by-step explanation:

Given that Mallik asked his teacher if there was a way to check his answer after writing equivalent expressions

To check answer in algebraic equations or equivalent expressions the best way is to substitute the answer for the variable in the expression and check whether the values are even.

Hence correct choice is option 2.

Substitute a number for the variable. If the simplified expressions have the same value, the expressions are equivalent.

wheres graph

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
