Answer:

step 1: move the -4 to the right: x^2 -2x = 4

step 2: add 1 to each side: x^2 -2x + 1 = 4 + 1

step 3: factor the left side and simplify the right side: (x-1)^2 = 5

step 4: take the square root of each side: x - 1 = sqr root of 5

step 5: move the 1 to the other side: x=\sqrt{5} + 1 and x = \sqrt{5} -1

−6 <3n+9 <21. whats the solution
tester [92]

We have

-6 < 3n+9 < 21.

From this we have system of inequality

-6 < 3n+9 \\3n+9 < 21

We have to simplify both inequalities

3n+9 > -6 \Longrightarrow n > -5 \\3n+9 < 21 \Longrightarrow n < 4

So we can conclude that

n > -5 \wedge n < 4 \Longrightarrow x\in(-5,4)

Hope this helps.

a constant is the a number on its own so in this case there would be none

a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80
