Point slope: y - y1 = m(x - x1), m is the slope
first picture
points (-4,-1) and (3,-3)
the slope between these points is
slope = (-3 - 1)/( 3 - (-4) ) = -2/7
if (x1, y1) = (-4, -1), then the slope-point form is
y + 1 = -2/7(x + 4)
___________
second picture (horizontal line)
from the graph, the slope is 0 because there is no rise for a horizontal line.
if (x1, y1) = (-2, 1), then the point slope form is
y - 1 = 0(x + 2)
_____________
third picture
from the graph, we have points (-2,2) and (2,-2) on the line. the slope is
slope = (-2 - 2)/(2 - (-2) ) = -1
if (x1, y1) = (-2,2), then point slope form is
y - 2 = -1(x + 2)
______________
fourth picture
if points (-2,-1) and (2,1) are on the graph, then slope is
slope = (1 - (-1) ) / (2 - (-2) ) = 1/2
with (x1, y1) = (-2,-1), the point slope form is
y + 1 = 1/2(x + 2)
_______________
fifth picture
we have points (-1,-2) and (1,2). the slope is
slope = (2 - (-2) ) / (1 - (-1) ) = 2
with (x1, y1) = (1,2), the point slope form is
y - 2 = 2(x - 1)
Answer:
Step-by-step explanation:
3b+8c=50c
3b=50c-8c
3b=42c
b=14c
So there are 14 cookies in each box.
Answer:
C. c = (xv - x) / (v - 1).
Step-by-step explanation:
v = (x + c) / (x - c)
(x - c) * v = x + c
vx - vc = x + c
-vc - c = x - vx
vc + c = -x + vx
c(v + 1) = -x + vx
c = (-x + vx) / (v + 1)
c = (-x + xv) / (v + 1)
c = (xv - x) / (v + 1)
So, the answer should be C. c = (xv - x) / (v + 1).
Hope this helps!
