Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y < -3x-2 -----> inequality A
The solution of the inequality A is the shaded area below the dashed line y=-3x-2
The slope of the dashed line is negative m=-3
The-y-intercept of the dashed line is (0,-2)
The x-intercept of the dashed line is (-0.67,0)
y > -3x+8 -----> inequality B
The solution of the inequality B is the shaded area above the dashed line y=-3x+8
The slope of the dashed line is negative m=-3
The-y-intercept of the dashed line is (0,8)
The x-intercept of the dashed line is (2.67,0)
using a graphing tool
The system of inequalities y < -3x-2 and y > -3x+8 has no solution (parallel lines)
see the attached figure
Answer:
A) 61.68
Step-by-step explanation:
This is an exponential decay of 0.875. The way to know that is to get that is (Pick a random number and divide by the number to the left of it) From there, there is a 12 hour difference from 7 am to 7pm! Divide 306.25/0.875 and divide it by 0.875 by the answer of that each time 12 times. The exact answer is 61.68402914
