Answer:
C. -7x
Step-by-step explanation:
Only one of the offered choices passes the horizontal line test: at most one point of intersection with any horizontal line.
__
A: a parabola opening upward, so will have two points of intersection with a general horizontal line (only one at the vertex).
B: a horizontal line, so will have an infinite number of points of intersection with a horizontal line.
D. A "V-shaped" graph that will generally have two points of intersection with a horizontal line (only one at the vertex).
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
Answer:
-(x + 5)(3x + 1)
Step-by-step explanation:
Step 1: Factor out negative
-1(3x² + 16x + 5)
Step 2: Factor quadratic
-(x + 5)(3x + 1)
Answer:
Step-by-step explanation:
13500/3 = 4500
4500 x 2 = 9000
