Answer:
1,000,000,000 as a power of 10, is: 10^12
Step-by-step Solution:
We can expand 1,000,000,000, and write this number as a multiplication sentence using only the number 10. By doing this, we can count the number of tens needed to be multiplied to get to his answer:
1,000,000,000 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10
Since 10 is multiplied by itself 12 times, we can therefore say that 10^12 is equal to 1,000,000,000
For this case we have the following equations:
x + y = 3
y = 2x - 15
Whose solution is given by:
x = 6
y = -3
Or equivalently the ordered pair:
(x, y) = (6, -3)
Answer:
(x, y) = (6, -3)

Since you have not included the plot, I'll just tell you how to find the function of the graph that you are looking for.
Function of the straight line has the general formula: y = mx + c
where:
m is the slope of the line and c is the y-intercept
So first we will need to find the slope (m):
Taking two points from the graph (x1,y1) and (x2,y2), the slope can be calculated as follows:
m = (y2-y2) / (x2-x2)
Then, we will need to find the y intercept.
we have the equation y = mx + c and we have m calculated
Take any point that belongs to the line and substitute with the values of x,y and m and then calculate c.
Now you have both m and c calculated, just substitute with the values in the formula.
30:60:90 is 3:6:9 in ratio form
19 dimes and 7 quarters
19 times 0.10 equalls 1.90
7 times 0.25 equalls 1.75
add 1.90 and 1.75
the answer is 3.65
