Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
You would multiply 160 by 32 and get an answer of 5120 centimeters cubed.
The correct answer is 400.
The correct answers should be:
43.) x=13
44.) x=3.125
45.) x=25
46.) x=2/7
