Answer:
153 coins will be there.
Step-by-step explanation:
The number of coin in the bottom row / or last row = 17
The number of coins in the second last row = 16

The number of coins in the second row = 2
The number of coins in the first row = 1
So the total number of coins = (Number of coin in the first row) + (Number of coins in the second row) + (Number of coins in the third row) + ....... + (Number of coins in the last row / seventeenth row)
Total number of coins = 1+2+3+....+16+17
Total number of coins = 
(NOTE: Sum of first n natural number = 
)
Answer:20 & 2
Step-by-step explanation:
20 x 2 =40
20+2=22
Answer:
(D)
Step-by-step explanation:
First, you have to graph the equation. Then you notice that it is a parabola facing downwards. This means that as the graph decreases on the left side, the x's become negative and the y's become negative. On the right side, the x's become positive and the y's become negative.
Answer:
It is a linear equation
Step-by-step explanation:
Answer:
y = 5x
Step-by-step explanation:
you can use the Slope-Intercept form of a line, which is:
y = mx + b where 'm' is the slope, and 'b' is the y-intercept
to find the slope, select any two points:
we can use (0,0) and (2,10)
now subtract the y-values and the x-values to get this fraction:
slope = 10-0 / 2-0
slope = 10/2 or 5/1
the y-intercept can be seen and is 0
therefore, equation of this line is:
y = 5x + 0 or
y = 5x
