The answer is A :The graph has closed circles on the left of the step and open circles on the right and includes the step
90/135 = 0.666666667
0.666 x 100 = 66.6 %
109.526 + 36.42 equals 145.946
Answer:
Graph of the new function will be vertically stretched by 2 units.
Step-by-step explanation:
A linear function is represented by the equation, y = 
This function has the slope =
and y-intercept = 4
If this function is stretched vertically by 'k' the the equation of the new function will be,
y = 
y =
---------(1)
If the slope of this equation is changed to
,
New equation of the function will be,
y =
---------(2)
Comparing equations (1) and (2),
a = 2
Therefore, graph of the new function will be stretched vertically by 2 units.
Answer:
d.81
Step-by-step explanation:
81 can be represented by a 9x9 square grid. The rest of the numbers would be represented on rectangular grids.
