Answer:
2 y 4
Step-by-step explanation:
Answer:
y=2x+3
root ![-\frac{3}{2} , 0](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B2%7D%20%2C%200)
Step-by-step explanation:
The solutions of x are 1 and ![-\frac{5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B2%7D)
Step-by-step explanation:
Given,quadratic equation is
![2x^2+3x-5=0](https://tex.z-dn.net/?f=2x%5E2%2B3x-5%3D0)
[
here a =2, b= 3 and c= -5]
![\Leftrightarrow x = \frac{-3\pm\sqrt{49} }{2.2}](https://tex.z-dn.net/?f=%5CLeftrightarrow%20x%20%3D%20%5Cfrac%7B-3%5Cpm%5Csqrt%7B49%7D%20%7D%7B2.2%7D)
![\Leftrightarrow x = \frac{-3\pm7}{4}](https://tex.z-dn.net/?f=%5CLeftrightarrow%20x%20%3D%20%5Cfrac%7B-3%5Cpm7%7D%7B4%7D)
Either x =1 or, ![x = -\frac{5}{2}](https://tex.z-dn.net/?f=x%20%3D%20-%5Cfrac%7B5%7D%7B2%7D)
Subtraction of a negative is the same as addition.
-10 - (-2)
-10 + 2 = -8
Your answer is: -8
1/7 x 2/3 =
2/21
hope this helps
