x - 12/6 = 9
x - 1/2 = 9
x = 9 + 1/2
x = (9/1)×2 + 1/2
x = 18/2 + 1/2
x = 19/2 = 9.5
Answer:
no because the ratio 3:4 is not equivalent to 4:5
Step-by-step explanation:
The average is calculated by adding all numbers and dividing by the count:
(2+4+5+6+8+2+5+6)/8 = 38/8 = 4.75
The mode is the number that occurs most often, however, this is the case for 2, 5 and 6. A data set can have multiple modes. 2, 5 and 6 are modes.
Answer:
f(x) = 4x³+16x²+4x-24
Step-by-step explanation:
Factors are (x+3)(x+2)(x-1)
(x+3)(x²+2x-x-2)
(x+3)(x²+x-2)
x³+x²-2x+3x²+3x-6
x³+4x²+x-6
This could have been the function but the intetcept is 6 here.
So we'll take a miltiple of this one such that the intercept becomes-24
-24/-6 = 4
That multiple is 4
f(x) = 4(x³+4x²+x-6)
f(x) = 4x³+16x²+4x-24
(2x+10)(2x+10) use FOIL to solve (First, Outer, Inner, Last)
4x^2+20x+20x+100
Combine like terms
4x^2+40x+100
