In order to solve an equation for a variable, we need to isolate that variable on one side of the equation (either left side or right side).
Following are some steps to solve equation/inequality in one variable:
1) Get rid constant number from on side by applying reverse operation of addition or subtraction.
2) Get rid variable terms from other side by applying reverse operation of addition or subtraction.
3) Combine like terms on both sides.
4) Get rid any coefficent ( a number in front of a variable) by dividing from both sides.
5) Finally you get a variable on one side and solution on other side.
Answer:
6x + 14 ≥ 28
Step-by-step explanation:
6 times a number (6x)
14 more than (so, add 14 to 6x)
greater than or equal to, so this symbol ≥
= 6x + 14 ≥ 28
SOLVED:
6x≥14
x≥2.333333333333333
Answer:
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward
The vertex represent a maximum
Convert the quadratic equation into vertex form
step 1
Factor -2
step 2
Complete the square
step 3
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (1,5)
2/10 as a percent would be 20%.
