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.
Scale factor between the two width is 3:1. As a result, the second length is 6×3=18 inches. Hope it help!
Answer:
30 pages in this book
Step-by-step explanation:
20% is equal 6 pages
so 80% is equal (80/20)*6+6=30
there are 5 thirds.
There are three in a whole number one, and the two left over. Then you add em up!
Answer:
x = 3, y = 8
Step-by-step explanation:
by substitution
4x + (x+5) = 20
5x + 5 = 20
x = 3
y = x + 5 = 3 + 5 = 8
