the division of the quarter is 6x
For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
Answer:
Step-by-step explanation:
plug y into the first equation:
8x+5y=24
8x+5(-4x)=24
8x-20x=24
-12x=24
x=-24/12
x=-2
then plug x to the second equation
y=-4
y=-4(-2)
y=8
x=-2
y=8
Answer:
29
Step-by-step explanation:
9+5=14+5=19+5=24+5=29
Answer:
x=1.167 y=8
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.
7x - 6y = 48
7(0) - 6y = 48
y2 = -8 x2 = 0
(x1,y1) and (x2,y2)
(6.857,0) and (0,-8)
6.857,0) and (0,-8)
The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 7x - 6y = 48
m = (y2 - y1)/(x2 - x1)
m = (-8 - 0)/(0 - 6.857)
m = 1.167
