Answer:

(Figure 1) Hence squaring both sides of an inequality will be valid as long as both sides are non-negative. Since square roots are non-negative, inequality (2) is only meaningful if both sides are non-negative. ... Hence, squaring inequalities involving negative numbers will reverse the inequality.

Is (2,3) a solution to the system of inequalities 4x+3y<20 <br> 10x+y>10

stiks02 [169]

Yes it is a solution because if you take the equation and plug the point in for the x and y :

4 (2) + 3 (3) < 20
8 + 9 < 20
17 < 20
which is true

10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true

5 more than 3 times a variable, x, is 23

Monica [59]

3x + 5 = 23

5 more than(addition) 3 times(multiplication) a variable(x) is(equals) 23

(you add 5 to 3x)

If you need to solve for "x", you need to isolate/get the variable "x" by itself in the equation:

3x + 5 = 23 Subtract 5 on both sides

3x + 5 - 5 = 23 - 5

3x = 18 Divide 3 on both sides to get "x" by itself

$\frac{3x}{3} =\frac{18}{3}$

x = 6
