Answer:

a=3

Step-by-step explanation:

x – 2y = 4

ax– 6y = 12

To have infinitely many solutions, the two equations have to be equal

Multiply the first equation by 3

3x -6y = 12

ax -6y = 12

a = 3

Find the sum of the following numbers without actually adding them1+3+5+7+9+11+13+15
Dovator [93]

S = 1 + 3 + 5 + ... + 11 + 13 + 15

S = 15 + 13 + 11 + ... + 5 + 3 + 1

==>  2S = (1 + 15) + (3 + 13) + (5 + 11) + ... + (15 + 1)

There are 8 terms in the sum, so

2S = 8 * 16 = 128

S = 128/2 = 64

What is the slope of the line equation 7x-3y=21
kramer
Equation: 7x - 3y = 21

3y = 7x - 21

Divide both sides by 3, 

y = 7/3x - 7

Compare it with principle equation, y = mx + c

Here, slope (m) = 7/3

In short, Your Answer would be: 7/3

Hope this helps!
