Step-by-step explanation:
the answer to this problem is -4
Answer: B
Step-by-step explanation:
(-3, -1) and (4, 5) are the points given
Slope formula: ![\frac{Y2-Y1}{X2-X1}](https://tex.z-dn.net/?f=%5Cfrac%7BY2-Y1%7D%7BX2-X1%7D)
![\frac{5--1}{4--3} = \frac{5+1}{4+3} \\](https://tex.z-dn.net/?f=%5Cfrac%7B5--1%7D%7B4--3%7D%20%3D%20%5Cfrac%7B5%2B1%7D%7B4%2B3%7D%20%5C%5C)
![\frac{5+1}{4+3} = \frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B1%7D%7B4%2B3%7D%20%3D%20%5Cfrac%7B6%7D%7B7%7D)
Answer:
Option A.
Step-by-step explanation:
we have
![x+\frac{b}{2a} =\pm\sqrt{\frac{b^2-4ac}{4a^2}}](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bb%7D%7B2a%7D%20%3D%5Cpm%5Csqrt%7B%5Cfrac%7Bb%5E2-4ac%7D%7B4a%5E2%7D%7D)
Simplify the right side of the equation
we know that
![\pm\sqrt{\frac{b^2-4ac}{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{\sqrt{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cpm%5Csqrt%7B%5Cfrac%7Bb%5E2-4ac%7D%7B4a%5E2%7D%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B%5Csqrt%7B4a%5E2%7D%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
so
The expression is
![x+\frac{b}{2a}=\pm\frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bb%7D%7B2a%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
therefore
x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a
