Answer:
x = 3/5 = 0.600
Step-by-step explanation:
Answer:
-8 - 36i
Step-by-step explanation:
Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
Answer:
You simply substitute 8 for n
A₈ =3(8)+4=28
Answer:
4
Step-by-step explanation:
25% is the same as 1/4.
1 is 1/4 of what number?
Answer: 4
You can also answer it with an equation.
Let x = the number you are looking for.
1 is 25% of x can be written as the following equation.
25% of x = 1
0.25x = 1
Multiply both sides by 4.
x = 4
Answer: 4
