X= -2 + the root of 5
OR
x= -2 - the root of 5
Answer:
If the slope is positive it is increasing if the slope is negative it is decreasing :)
Example:
Y=mX+b
If m is positive it is a positive slope
Answer:
x=−8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(x+5)=21
(−7)(x)+(−7)(5)=21(Distribute)
−7x+−35=21
−7x−35=21
Step 2: Add 35 to both sides.
−7x−35+35=21+35
−7x=56
Step 3: Divide both sides by -7.
−7x/−7 = 56/−7
x=−8
3x(x+2)-8(x+2)=4
3x^2+6x-8x-17=4
3x^2-2x-21=0
3x^2-9x+7x-21=0
3x(x-3)+7(x-3)=0
(x-3)(3x+7)=0
Either
x-3=0
x=3
Or
3x+7=0
x=-7/3
