Answer:
504 combos
Step-by-step explanation:
Cannot use digits twice and last is '7'
9 digits for first place choice
8 digits for second place
7 digits for third place
only '7' for fourth place 9 x 8 x7 = 504 combos
Answer:
The variable is n
The coefficient is 2
And the solution to n is 10.
Step-by-step explanation:
The number in the equation is the variable. The coefficient is the number before the variable. And a number next to a letter means you multiply. So 2*5=10 10-3=7
-8x - 60 = -164
Add 60 to both sides, because whatever you do on one side, you have to do it to the other side
-8x = -104
Divide -8 to both sides
x = 13
depends on what u believe in if u think he existed then yes if you dont then no
Answer:
x - 2y + 1 = 0
Step-by-step explanation:
This line goes through the points (-3, -1) and (3, 2). Going from the first oint to the second, we see that x increases by 6 (this is the 'run') and y increases by 3 (this is the 'rise'). Thus, the slope is m = rise / run = 3/6 = 1/2.
Starting with the slope-intercept form y = mx + b, we get
y = 2 = (1/2)(3) + b, or (after multiplying all terms by 2):
4 = 3 + 2b, or 1 = 2b, or b = 1/2
Then the equation of this line is y = mx + b, or y = (1/2)x + 1/2.
We must put this into standard form. Multiplying all terms by 2 yields
2y = x + 1, or x - 2y + 1 = 0
