Answer:
x1 + x2 = -b/a
The answer is based on "Vieta's Formulas" for the sum and product of roots. In other words, in its simplest form, it states that:
for ax^2 + bx + c = 0
- x1 + x2 = -b/a
- x1 × x2 = c/a
Answer:
The simplified form of inequality is m > - 4. So, the solution will be the right side of x = - 4 line.
Step-by-step explanation:
We have to draw the graph of the solution of the given inequality - 3m + 18 < 30 ......... (1)
Step 1: Simplify the inequality as simple as possible.
-3m + 18 < 30
⇒ - 3m < 12
⇒ m > - 4 {Dividing both sides with - 3 and hence there is the change in inequality sign.}
Step 2: Now, draw the line x = - 4 in the coordinate plane. It will be a vertical line on the coordinate plane and at a distance of 4 units in the negative direction from the y-axis.
Step 3: Now, shade the portion right side of the line (As m > - 4, so the value of m will be greater than - 4)but do not include the line. (Answer)
