Answer:
C
Step-by-step explanation:
A can be from 2- 9 ( 8 digits)
B can be 0 to 9 (10 digits)
C can be 0 to 9 (10 digits)
Each of the X's can be 0 to 9 (10 digits)
To get the number of possibilities, we multiply them to get:
8 * 10 * 10 * 10 * 10 * 10 * 10 = 8,000,000
But now, 1 number (867-5309) is restricted, so the number of possibilities decrease by 1:
8,000,000 - 1= 7, 999, 999
Correct answer is C
Answer:
The equation is y = -2/5x + 4
Step-by-step explanation:
First we have to find the slope of the line. In order to do so, solve the first equation for y.
2x + 5y = 20
5y = -2x + 20
y = -2/5x + 4
This gives us a slope of -2/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.
y - y1 = m(x - x1)
y - 6 = -2/5(x - -5)
y - 6 = -2/5(x + 5)
y - 6 = -2/5x - 2
y = -2/5x + 4
When we arrange the numbers in such an order that it starts from the smallest number and goes towards the largest number, that order is called ascending order.
Prime factors of 63 are : 3, 3, 7
As 3 repeats and 3 is smaller than 7 so, when we write this in ascending order as the product of these, we write in such a way;
63 = 3 x 3 x 7 = 3² x 7
Now 3² = 9 and 9 is greater than 7,so,
63 = 7 x 9
Median because there is a low-outlier in 2,000 which can skew the mean because of 1 data point. Median removes the possibility of this from happening
