Answer:
Step-by-step explanation:
Each child receives
number of apples divided by number of children, that is
each child receives apples
A=lxw
a=1/3·1 1/3
a=1/3·4/3
a=4/9
so the area is 4/9 inches squared
M= -4/3
y=mx+b
y=(-4/3)x+b
5=(-4/3)*3 +b
b= 9
y=(-4/3)x+9
Answer:
It is 11.
Step-by-step explanation:
10.246950766 is rounded to 11.
Okay I think there has been a transcription issue here because it appears to me there are two answers. However I can spot where some brackets might be missing, bear with me on that.
A direct variation, a phrase I haven't heard before, sounds a lot like a direct proportion, something I am familiar with. A direct proportion satisfies two criteria:
The gradient of the function is constant s the independent variable (x) varies
The graph passes through the origin. That is to say when x = 0, y = 0.
Looking at these graphs, two can immediately be ruled out. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations.
This leaves B and C. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear.
This leaves C as the odd one out.
I hope this helps you :)
