Answer:
Step-by-step explanation:
hello :
f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1
f(x) = -2((x²-2x+1)-1)+1
f(x) = -2((x-1)²-1)+1
f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)
the axis of symmetry is x=1
Answer:95.62
Step-by-step explanation:
This is easy all you have to do is use the formula of the volume which is v=l.h.w
(X+9)(x+4)(x+5)= v
(X+9)(x^2+9x+20)
X^3+18x^2+101x+180=v
Answer:
6 bows
Step-by-step explanation:
First find a common denominator. In this case, it would be eight. So now you would multiply your numerator by however much you multiplies your denominator.
3/4 would become 6/8.
6/8 divided by 1/8 is 6.
Answer:
c. 4y -x = 8
Step-by-step explanation:
Each of the equations can be put into slope-intercept form (solved for y) as follows:
a: y = 4x +9
b: y = 4x -8
c: y = (1/4)x +2
d: y = 4x -4
___
The equations containing the term "4x" all describe parallel lines. The equation containing (1/4)x describes a line that intersects the given line. It is not parallel to the others.
