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

Sedaia [141]

Answer:

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: $3x - 2$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: $-9y$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: $-7x^2 + 4x$

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: $-\frac{1}{2} x^2$

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: $8xy$

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

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

Find the GCF of 38, 76, and 114.

valentina_108 [34]

Answer:

<em>GCF = 38</em>

Step-by-step explanation:

<em>38 = 2×19</em>

<em>76 = 4×19 = 2²×19</em>

<em>114 = 2×3×19</em>

<em>GCF = 2×19 = 38</em>

Can someone please help me-

puteri [66]

Answer:

can be expressed as decimal: 0.025

s= 1.025* $250

= $256.25

after 8 years

s= $250* 1.025^8

~$304.6

earned $54.6

Step-by-step explanation:

2 and a half is equivilant to 2.5

because it is a % (out of 100) move the decimal 2 places down

2.5-->0.25-->0.025

so can be expressed as decimal: 0.025

interest after 1 year is:

original amount of money * (interest rate+1.0)

+1 because you are adding on to 100%. you already have 100%. if it was just the interest rate, the amount of money would go down.

so

s= 1.025* $250

=1.025* 250

=256.25

interest after 8 years,

that means you have to take the original, and multiply it by the interest rate, then the new original multiply by intrest rate a total of 8 times

to do this use an exponent, because exponents base the total off the total before them. if that makes any sense srry

s= $250* 1.025^8

~$304.6 (I used calculator)

to get her earnings, subtract the new amount of money with her original amount of money

304.6-250

=54.6

$54.6

hope this helps

What is the value of x in the equation x – y = 30, when y = 15?

asambeis [7]

X= 45, you would place 15 into y's place, which would give you x-15= 30... then you would add 15 to both sides, which would give you x=45<span />
