Because you need to Move constant to the right-hand side and change its sign Move variable to the left-hand side and change its sign Collect like terms Multiply both sides of the equation by -1 which the answers is x=4

Solve the following absolute value equation for the unknown. Show all of your work for full credit. |-3h – 6| ≤ 3

ss7ja [257]

Answer:

$-3 \le h \le 1$ .

Step-by-step explanation:

Apply the property of absolute values: if $a \ge 0$ , then $|x| \le a \iff -a \le x \le a$ . By this property, $|- 3\, h - 6 | \le 3$ is equivalent to $-3 \le -3\, h - 6\le 3$ . That's the same as saying that $-3\, h - 6 \ge -3$ and $-3\, h - 6 \le 3$ .

Add $6$ to both sides of both inequalities:

$-3\, h \ge 3$ and $-3\, h \le 9$ .

Divide both sides of both inequalities by $(-3)$ . Note that because $-3 < 0$ , dividing both sides of an equality by this number will flip the direction of the inequality sign.

$-3\, h \ge 3$ would become $h \le -1$ .
$-3\, h \le 9$ would become $h \ge -3$ .

Both inequalities are supposed to be true. Combining the two inequalities to obtain:

$-3 \le h \le 1$ .

One third of a bird’s eggs hatched. If 2 eggs hatched, how many eggs did the bird lay?

iogann1982 [59]

Hello there,
Since one third eggs hatched, 1/3=2eggs. In order to find the total amount off eggs, 1/3+1/3+1/3:2+2+2=6.
Hope this helps!!
