Answer:
3x-8y-16 = 0
Step-by-step explanation:
From the given question we come to know of certain number of facts and they are:
At 1:00 PM the water level of the pond was = 13 inches
At 1:30 PM the water level of the pond was = 18 inches
At 2:30 PM the water level of the pond was = 28 inches
From the above given facts we can easily find the amount of water changing every half an hour.
Amount of increase in water from 1:00PM to 1:30 PM = (18 - 13) inches
= 5 inches
Amount of increase in water level from 1:30PM to 2:30PM = (28 -18) inches
= 10 inches
From the above two deductions we can come to the conclusion the the constant rate of change in water level is 5 inches for every half an hour.
Answer:
d = 12
c = 4
so I think d > c
Step-by-step explanation:
1 x 12 = 12
0.75 x 4 = 3
12 + 3 = 15
Answer:
(-3a+-2x)(2a+-1x)=0
Step-by-step explanation:
Simplifying
x2 + -1ax + -6a2 = 0
Reorder the terms:
-1ax + -6a2 + x2 = 0
Solving
-1ax + -6a2 + x2 = 0
Solving for variable 'a'.
Factor a trinomial.
(-2a + -1x)(3a + -1x) = 0
