Answer:
The formula for the vertex of the parabola is -b/a. Plugging this in we get -(-4)/1 or 4.
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(2x−4)=4x
(−2)(2x)+(−2)(−4)=4x(Distribute)
−4x+8=4x
Step 2: Subtract 4x from both sides.
−4x+8−4x=4x−4x
−8x+8=0
Step 3: Subtract 8 from both sides.
−8x+8−8=0−8
−8x=−8
Step 4: Divide both sides by -8.
The answer is permutation !
Answer:
(f×g)(x) = 2x³ +x² -14x -7
Step-by-step explanation:
(f×g)(x) = f(x)×g(x) = (2x +1)×(x² -7)
= 2x(x² -7) +1(x² -7)
= 2x³ -14x +x² -7
(f×g)(x) = 2x³ +x² -14x -7
If the linear equations form parallel lines or if the answer is not true like 0=8 or 5=18 it means the linear equations have no solutions. If the linear equations form 2 lines that are on top of each other or the answer is true for example 0=0 or 5=5 then the linear equations will have infinitely many solutions. If a linear equation gives you a single answer like x= 7 an y=9 then the linear equation only has one solution
