Answer:
x = 
Step-by-step explanation:
FOIL what is in the parentheses by multiplying terms by -4.
-4(3x) = -12x and -4(2/6) = -4/3
now add these products: 
That is the simplified product ^, but assuming you're supposed to set the equation to equal 0...
Set equation to 0 and add the fraction to both sides. Rewrite as 
Divide both sides by -12 to get variable, x, alone. Multiplying 4/3 by -1/12 is the same as dividing 4/3 by -12. The negative sign from the -12 make the quotient negative.
x =
We can find slope of a graph using the formula :
Slope : y2 - y1 / x2 - x1 = slope.
Slope : tan Θ = slope.

PLEASE MARK ME BRAINLIEST ☺️
Answer:
b is the correct answer.
Step-by-step explanation:
Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.
Answer: Asymptote at y=0; range of 0,infinity; y-intercept of (0,1)
Step-by-step explanation:
Check the picture below
so.. .hmmm the vertex is at the origin... and we know the parabola passes through those two points... let's use either.. say hmmm 100,-50, to get the coefficient "a"
keep in mind that, the parabolic dome is vertical, thus we use the y = a(x-h)²+k version for parabolas, which is a vertical parabola
as opposed to x = (y-k)²+h, anyway, let's find "a"
now.. .your choices, show.... a constant on the end.... a constant at the end, is just a vertical shift from the parent equation, the equation we've got above.. is just the parent equation, since we used the origin as the vertex, it has a vertical shift of 0, and thus no constant, but is basically, the same parabola, the one in the choices is just a shifted version, is all.
