Answer:
3.5 is the slope and it is the rate of change.
Step-by-step explanation:
the slope is the number with the variable because you use the formula
y = mx + b
the slope is the rate of change.
Answer:
d
Step-by-step explanation:
45:60*20=15 miles the distance she traveled at 45 mph
18-15=3 miles she traveled at 20 mph
3/20=0.15 hours she traveled to reach the work
0.15*60=9 minutes
20+9=29 minutes she traveled to work
7:15+29=7:44
Kenya arrive at work at 7:44
Step-by-step explanation:
3 tan 2x - 4 tan 3x = tan² 3x * tan 2x
3 (tan 2x - tan 3x) = tan 3x + tan² 3x * tan 2x
= tan 3x (1 + tan 3x * tan 2x)
3 (tan 2x - tan 3x)/(1 + tan 3x * tan 2x) = tan 3x
3 * (- tan x) = tan 3x
-3tanx = (3 tan x - tan³ x) / (1 - 3 tan² x)
3 - tan² x = - 3 + 9 tan² x
tan x = + √3 /√5 or - √3/√5
