Well he started off right by solving for y=y to find the abscissa of the intersection points between the two points,but then he assumed that their ordinate (y coordinates) are both zero,which is incorrect obviously. To find their ordinate,all we have to do is plug the x values into any of the two equations, since they both will pass through that point ੴ
I chose to plug the values in the second linear equation, since it's easier to compute

Answer:
The explicit formula for a given geometric sequence is of the form
Step-by-step explanation:
Given sequence is 
Let 
To find the common ratio r:
Therefore r=-3
Therefore r=-3
Therefore common ratio is -3
Therefore given sequence is geometric sequence.
The explicit formula for a geometric sequence is 
, where common ratio is r.
From given sequence we are having r=-3
Therefore the explicit formula for a given geometric sequence is of the form 
Answer:
graph the equation by transforming the "parent graph" accordingly. ... For example, for a positive number c , the graph of y=x2+c is same as graph y=x2 shifted c units up. Similarly, the graph y=ax2 stretches the graph vertically by a factor of a .
Step-by-step explanation:
We can solve using y = 0 and solving for x.
81x + 18(0) = 9
81x = 9
x = 1/9
Therefore, the point (1/9, 0) sastisfies the equation.
Best of Luck!
Answer:
rational
Step-by-step explanation:
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. The number 22/7 is a irrational number
Kono Dio Da!!!
