The rate of change of a line is regarded as the slope/ gradient (m) of the line
The slope/ gradient (m) of the line moving through points (x₁,y₁) and (x₂,y₂) is given as
On substituting the above values in the formula above we will have the slope to be
Therefore,
The rate of change of the line through (2,3) and (3,8) is 5
Answer:
???
Step-by-step explanation:
Answer:
x=17
Step-by-step explanation:
This should be for a "kite": AD=DC, AB=BC and ∠A=∠C
8x-27 = 3x+58
5x = 85
x = 17
Sylvia puts in $121.
10% of (multiply) $210.
210= 100 each person plus an additional ten from Leroi
so .10*210 = $21.
Add Sylvia's $100 plus $21 and viola, $121
The answer to this is the second choice
