8: slope is 1/2 and y intercept is 0
9: slope is 7/4 and y-intercept is 0
Answer:
(1/2, 0), (0, -2)
Step-by-step explanation:
We can determine the slope from ...
slope = (change in y)/(change in x) = (10 -2)/(3 -1) = 8/2 = 4
Then an equation for the line can be written for slope m and point (h, k) as ...
m(x -h) -(y -k) = 0
Using the slope we calculated and the first point, we have the equation ...
4(x -1) -(y -2) = 0
4x -4 -y +2 = 0 . . . . . eliminate parentheses
4x -y = 2 . . . . . . . . . . put in standard form
Now, we can divide by the constant on the right to put this into intercept form:
x/(x-intercept) + y/(y-intercept) = 1
x/(1/2) + y/(-2) = 1
The x-intercept is 1/2; the y-intercept is -2.
2000 has three zeros and 10 has one, so you add another zero to 2000 so it makes it 20,000
Answer:
C x = 4096
Step-by-step explanation:
log8 x = 4
Raise each side to the base of 8
8^ log 8 (x) = 8^4
x = 8^4
x = 4096
