Answer:
y = 2x
Step-by-step explanation:
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 4, y = 8, that is
8 = 4k ( divide both sides by 4 )
2 = k, thus
y = 2x ← equation of proportion
Since y is anything greater than 2, you would draw a straight line across the point (from left to right) and if you had to shade you would shade above it (:
Answer:
pretty sure its,100
Step-by-step explanation:
Answer:
The curve (B) matches the graph of y=x²-4x.
Answer:
Using the Pythagorean theorem for isosceles right triangle, the length of the hypotenuse is sqrt( 2 x 10^2) = ~14.1 in
Hope this helps!
