Answer:

Step-by-step explanation:
Solve

For x=-1/2 and y=-3
substitute the value of x and the value of y in the expression above

Remember that

so

Convert to mixed number

Hi!
Yes, it is. When we have one inequality composed of two inequalities, we call this a double inequality.
A double inequality would look something like <em>-5 < 4x < 10.
</em>Hopefully, this helps! =)<em>

Answer:
<h2>No,they are not</h2>
Step-by-step explanation:
An algebraic expression must contain and unknown value to solve for.
6x + 0.8 = 1.4....subtraction property .... subtract 0.8 from both sides
6x = 1.4 - 0.8 ...simplify
6x = 0.6 ... division property ... divide both sides by 6
x = 0.6/6 ...simplify
x = 0.1
Answer:
1.2x - 10.8 - 2.3x - 9.2 = -1.1x - 20; Rewrite as follows. (x 2y)(xy 2) = (x 2 x)(y y 2) ... x + 2.3; - x / 5 = 2; (x - 4) / (- 6) = 3; (-3x + 1) / (x - 2) = -3; x / 5 + (x - 1) / 3 = 1/5 ... 2 x 2 - 8 = 0; x 2 = -5; 2x 2 + 5x - 7 = 0; (x - 2)(x + 3) = 0; (x + 7)(x - 1) = 9; x(x - 6) = -9 ... For what value of the constant k does the quadratic equation x 2 +2x = - 2k .
