Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2^ e. 8xy (The ^2^ means squared!)

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a:

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b:

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c:

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d:

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e:

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

answer: ouch. thats difficult

step-by-step explanation:

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female
