Answer:
hypotenuse^2= 5^2+8^2
hypotenuse= 3
Step-by-step explanation:
You are given the points in which the line intercepts. Using this info, we can use these numbers to find the slope.
m = (y2-y1)/(x2-x11) = (2-4)/(2-1) = -2/1 = -2
Our end result we want is the point-slope intercept formula : y=mx+b
We are still missing b, the intercept, so pick either of the two points (it doesn't matter which) and plug them into the equation. I will use (1,4), but again you could use either.
4 = (-2)*1 + b
6 = b
So now your final equation for the line after plugging in b and m is
y = (-2)x +6
Answer:
x=8
Step-by-step explanation:
the y-value in the first pair decreased by half, so the x-value must double due to inverse variation.
Answer:
C. 0.314.
Step-by-step explanation:
1/2 is rational. The answer is another rational number.
The only rational number in the list is 0.314.
