If the roots are 3, 2 and -3 then the function is created by multiplying
(x-3) * (x-2) * (x+3)
x^2 -5x +6 * (x+3)
x^3 -5x^2 +6x + 3x^2 -15x +18 = 0
x^3 -2x^2 -9x +18 = 0
Answer:
z = - 1
Step-by-step explanation:
z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side
z + z - 6 - 2 = - 10 , that is
2z - 8 = - 10 ( add 8 to both sides )
2z = - 2 ( divide both sides by 2 )
z = - 1
Answer:
c
Step-by-step explanation:
the ratio is 2/8.
2/8 = 1/4.
a)
8/20 = 2/5 is NOT equal to 1/4.
b)
12/45 = 4/15 is NOT equal to 1/4
c)
6/24 = 1/4 perfect
d)
2/40 = 1/20 is NOT equal to 1/4
Answer:
x = 1 and x = 3.
Step-by-step explanation:
y = 2 - 8x + 6
y = 2( - 4x + 3)
y = 2(x - 3)(x - 1)
So, the x-intercepts would be at...
x-3 = 0
x = 3
and
x - 1 = 0
x = 1
Hope this helps!
.82
When changing a percentage to a decimal you will divide the number by 100. 82/100= .82
To change it back to percentage you will take .82 and multiply by 100 or simply move the decimal two stops to the right, making 82. or 82%
