80=-8a
We are trying to solve for a. So we need to get a alone. To do that we have to divide each side by -8.
80/-8= -8a/-8
Once you have solved each side you will get the following.
-10=a
Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
Answer:
X ≥ 10
Step-by-step explanation:
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.
