Answer:
Hello,
Step-by-step explanation:
Roots are -2 and 4
y=k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9=k*(1+2)(1-4) ==> k=1
Equation of the parabola is y=(x+2)(x-4)
But you don' t have given the graphs !!!!
You said | w | + 1.2 > 0.8
Subtract 1.2 from each side: | w | > -0.4
The absolute value of a number is always positive.
EVERY value of 'w' has an absolute value greater than -0.4 .
EVERY number is a solution to the equation.
There are an infinite number of them.
Answer:
B
Step-by-step explanation:
in table B if x = 1 y cannot equal both 1 and -1
no function can have x equal to two or more unique y's
Answer:
x=-12
Step-by-step explanation:
2-3/4x=11
3/4x=2-11
3/4x=-9
x=-9/(3/4)
x=(-9/1)(4/3)
x=-36/3
x=-12
