Step-by-step explanation:

First, make them on one side of the formula in the form of $ax^2+bx+c=0$ which is $4x^{2} -2x-3=0$

Next, insert the corresponding number in the quadratic formula, $\frac{-b+\sqrt{b^{2}-4ac } }{2a} ,\frac{-b-\sqrt{b^{2}-4ac } }{2a}$ , and the answer can be calculated.

7x−4≥−15+2x solve in interval notation

Leviafan [203]

Answer:

[-11/5,∞)

Step-by-step explanation:

1. Add 4 to both sides: 7x-4+4≥-15+2x+4

2. Simplify: 7x≥2x-11

3. Subtract 2x from both sides: 7x-2x≥2x-11-2x

4. Simplify: 5x≥-11

5. Divide both sides by 5: 5x/5≥-11/5

6. Simplify: -11/5
