From the equation of a parabola identify the focus and directrix:

x=8y^2

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
