Answer:
x-intercept = 6
y-intercept = -16
Step-by-step explanation:
8x-3y=48
Step 1
To find the y-intercept, we rewrite the equation into the form,
y=mx+c
Where c = y-intercept (this means that the straight line cuts the y-axis on a graph)
8x-3y=48
8x-48=3y
3y=8x-48
y=8x/3 - 48/3
y=8x/3 - 16
y=2.67x-16
Comparing y=mx+c and y=2.67x-16,
c corresponds to -16.
Therefore, the y-intercept is -16
Step 2
To find the x-intercept, we rewrite the equation into the form,
x=ay+c
8x-3y=48
8x=3y+48
x = (3/8)y + 48/8
x = 0.38y + 6
Comparing x=ay+c and x=0.38y+6,
c corresponds to 6
Therefore, the x-intercept is 6
Answer:
68%.
Step-by-step explanation:
Dalvin's finishing time is normally distributed with a mean of 65 seconds and a standard deviation of 1 second.
Under the empirical rule, 68% of the results will be within 1 standard deviation.
Since the standard deviation is 1 second, 68% of Dalvin's finishing time will be between 64 and 66 seconds.
Are both the 1 and a over 6
All the sides add like a rectangle with two sides measuring 4 and two measuring 2 so you would add 4+4+2+2=12
