8 0

Answer:

1)x = 2, x =-10

Step-by-step explanation:

3x + 12 = 18 or -18

if 3x + 12 = 18 ➡ 3x = 18 - 12 ➡ x = 2

if 3x + 12 = -18 ➡ 3x =-18 - 12 ➡ x = -10

Write an equation for the line in slope-intercept
Tamiku [17]
The equation would be: y=3x+5
The line crosses the y-axis at 5, so that’s the y-intercept.
The slope is 3 because it goes up by 3 and then 1 to the right, as a fraction it’s 3/1 which is just 3

1. Explain why n root a^n= |a| when n is even, but not when n is odd.
kogti [31]

Step-by-step explanation:

In the expression a^n, for integer values of n greater than 1, there are n factors. For example, a^2 = a * 2 (2 factors), a^3 = a * a * a (3 factors), etc.

For a non-negative value of a, a^n is non-negative for all values of n.

If a is negative, and n is even, then a^n is non-negative.

If a is negative, and n is odd, then a^n is negative.

|a| is non-negative for all values of a.

sqrt_n(a^n) is negative for negative a and odd n, but |a| is always non-negative, so sqrtn(a^n) cannot equal |a| for odd n.

891

prime factors   number to factorize

3                          297

3                          99

3                          33

3                          11
