Answer:
there are 8 million different phone numbers whose phone numbers whose digits aren't 0 or 1
Step-by-step explanation:
a) 2x = 8 x 3
2x = 24
x = 12
b) 3x = 12
x = 4
Answer:
The answer to your question is y= 3x - 4.
Step-by-step explanation:
Plot the points (1,-1) and (2,2) and get your slope, in the case of slope-intercept form "m" using the rise/run method. You rise 3 units and run one unit to the right to get from (1,-1) to (2,2), so your slope is 3/1 or just simply 3. -4 is your y-intercept, or "b", because if you plot the two aforementioned points (1,-1) and (2,2) and make a line with them, your line meets the y-axis at the point (0, -4). Hope this helps!
Answer:
No solutions
Step-by-step explanation:
To find the number of solutions, solve the equation.
15x + 6 = 15x + 9 Distribute the 3 to the (5x + 2).
(15x - 15x) + 6 = (15x - 15x) + 9 Subtract 15x from both sides.
6 = 9 Since all of the variables cancel each other out, you are left with an untrue statement, so therefore, there are no solutions to this equation.
