Answer: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
Answer:
(14, 2 )
Step-by-step explanation:
Use the midpoint formula
[0.5(x₁ + x₂), 0.5(y₁ + y₂) ]
with (x₁, y₁ ) = (16, 7) and (x₂, y₂ ) = (12, - 3)
midpoint = [0.5(16 + 12), 0.5(7 - 3) ] = [0.5(28), 0.5(4) ] = (14, 2 )
A function and it's inverse function, when graphed, will be symmetrical across the line y=x.
Without seeing your graphs, I can't tell you if it's g or h. Look for the function which mirrors 'f' across y=x, which is a diagonal line passing through the origin (0,0) of the graph.
