X^2+5x+6=0
(x+3)(x+2)=0
x-3, x-2
Answer:
x = 10
Step-by-step explanation:
![x - 7 = 13 - x](https://tex.z-dn.net/?f=x%20-%207%20%3D%2013%20-%20x)
Step 1 : Collect like terms and simplify
![x + x = 13 + 7 \\ 2x = 20](https://tex.z-dn.net/?f=x%20%2B%20x%20%3D%2013%20%2B%207%20%5C%5C%202x%20%3D%2020)
Step 2 : Divide both sides of the equation by 2
![\frac{2x}{2} = \frac{20}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B20%7D%7B2%7D%20)
Step 3 : Simplify by cross cancellation of common term : 2
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Quadratic Formula is (-b ±√(b²-4ac))/2a
With that being said:
y=2x²-5x-1 is in the correct form of ax²+bx+c
Now just plug in:
5±√(25-4(2 x-1))
5± √25+8
(5±√33)/2(2)
Answer is D
100% Sure

1.y-4.90 = 2.4(x-1) 2. 24x-10y= -25
Step-by-step explanation:
The point-slope form of an equation is written as ;
y-y₁ = m(x-x₁) where the focus is on the slope of the line and a point on the line.
In this case, y-4.90 = 2.4(x-1)
The standard form an equation is written as :
Ax+By=C ,where x and y are variables and A,B and C are integers.
In this case; 24x-10y= -25
