Answer:
x = -6/65
Step-by-step explanation:
Perform the indicated multiplications: 4(-8x+5) - 1(33x-26), obtaining:
-32x + 20 - 33x + 26
Combining like terms, we get
-65x = 6, or
x = -6/65
Answer:
2a times the sq root of 2a or 2a (2a)**1/2
Step-by-step explanation:
(8a**3)**1/2 =
((2**2 * 2) (a**2) (a))**1/2 then take out and squares
2a (2a)**1/2
or 2a times the sq root of 2a
Answer:
Yes
Step-by-step explanation:
4(3) - 28 = -16
12= -16 + 28
12 = 12
Hope that helps!
The sequence is dividing by 1.5. When you divide 81 by 1.5 you get 54. When you divide 54 by 1.5 yippy get 36.
Answer:
(-4,1)
Step-by-step explanation:
The given parabola is
When we rewrite in vertex form, we get;
Or
When we compare to:
We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)
