What is the value of x in the equation –x = 4 – 3x + 6? (5 points)

olga_2 [115]

-x = 4 -3x + 6

First, let's get x on one side.
Add 3x to both sides.

-x + 3x = 2x
-3x + 3x = 0

We now have:
2x = 4 + 6

Combine like-terms (add 4 to 6)
4 + 6 + 10

2x = 10

Divide both sides by 2 to solve for x.
2x / 2 = x
10 / 2 = 5

We're now left with:
x = 5

I hope this helps!

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.

In the way you asked the question, the answer is already there but I am going to assume u are asking how many bracelets you can make which would then put the answer at almost 9 bracelets.
