3.5x-10>-3 add 10 to both sides
3.5x>7 divide both sides by 3.5
x>2
... now for the other inequality:
8x-9<39 add 9 to both sides
8x<48 divide both sides by 3
x<6
So we have x>2 and x<6, so the compound inequality is:
2<x<6 and this means that the solution set is:
x=(2, 6)
Answer:When n is an odd number, ![\sqrt[n]{a}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D)
is a real number for all values of a. Then, the domain is the real domain.
Answer:
So any time you are multiplying something, you are making "groups of"
so 3 groups of 2 = 6, 4 groups of 3 = 12
But with decimals or fractions, because they are a value less than zero, the numbers become increasingly small instead of bigger, like standard multiplication.
So for example, 1 group of 1/2 = 1/2
2 groups of 1/4 = 1/2
and so on
hope this helps!
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
Opposite sides of a parallelogram are congruent.
3x+ 2= 4x-3
Subtract 3x from both sides
2= x -3
Add 3 to both sides
5= x
2y+7=4y-9
Subtract 2y from both sides
7= 2y -9
Add 9 to both sides
16 = 2y
Divide by 2 on both sides
8 = y
