Greater x: -6.59
Step-by-step explanation: khan academy
Its simple what you do is you subtract not divide because if you where dividing you would be putting something into groups equally and not Addison because your not trying to find how much in all so it would be Subtraction another way is to see if there is how many more or How much more so if you see that then you know that its Subtraction! Hope this helps!:)
Answer:
Step-by-step explanation:
x=55. Explanation: If x varies inversely as y , then that means: y=kx. Let's multiply both sides of the equation by x to find k . k=xy.
Answer:
y=-2x-1
Step-by-step explanation:
First we need to know the slope-intercept equation:
y=mx+b
m: slope
b: y-intercept
First we find the slope:
Slope = (y₂-y₁)/(x₂-x₁)
Use any two x and y values on the table:
Slope = [-5-(-3)]/(2-1) = -2/1 = -2
Now we find the y-intercept:
y=mx+b
y=-2x+b
We plug in a pair of x and y values into the equation:
-3=-2(1)+b
-3=-2+b
b=-1
So the slope-intercept equation is:
y=-2x-1
