Answer:
x < -4 or x > 8
On a number line, make two arrows:
1) going towards left from -4 with an open circle at -4
2) going towards right from 8 with an open circle at 8
Step-by-step explanation:
l -4 +2x l -3 > 9
l -4 +2x l > 12
l 2x - 4 l > 12
2x - 4 > 12
2x > 16
x > 8
-2x + 4 > 12
-2x > 8
x < -4
On a number line, make two arrows:
1) going towards left from -4 with an open circle at -4
2) going towards right from 8 with an open circle at 8
Answer:
x=8.2
Step-by-step explanation:
6.7x=5.2x+12.3
subtract 5.2x from 6.7x
1.5x=12.3
divide 1.5 by 12.3 to get x alone
x=8.2
Answer:
If n is a positive integer that is greater than
x and a
is a real number or a factor, then
a x n = n √ a x . a x n = n √ a x
X>82 you have to isolate the variable by dividing each side by factors that don’t contain the variable.
