Answer:
8 + 2 * X = P
2 + 3 * X = C
Step-by-step explanation:
By means of the statement we have to:
Phillp case: "Charges $ 8 the first time he walks a dog and $ 2 per walk after that" that is:
P = 8 + 2 * X
Where X would be the number of walks.
Carrie case: "Charge $ 2 the first time he walks a dog and $ 3 per walk after that" That is:
C = 2 + 3 * X
Where X would be the number of walks.
Therefore the equation system would be:
8 + 2 * X = P
2 + 3 * X = C
P and C earnings of Phillp and Carrie respectively.
Answer:
D) x + y ≤ -4
3x + 2y ≤ -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
we will choose the system of inequalities
x + y ≤ -4
3x + 2y ≤ -5
x + y = -4 ...(i)
3x + 2y = -5..(ii)
Multiply equation (i) with '3'
3x + 3y = -12
3x + 2 y = -5
<u> - - +</u>
<u> 0 + y = -7 </u>
<u>Step(ii):- </u>
Substitute y = -7 in equation (i)
x + y = -4
x - 7 = -4
x = -4 + 7
x = 3
<em>The solution of the given inequalities is ( 3, -7)</em>

Answer:
700/(150/3) = 14 hours
Step-by-step explanation:
150/3 = x miles per hour
50 miles per hour
700/50 = 14 hours
Answer:
y = -3/2x + 3
Step-by-step explanation:
We can get 2 points from the graph
(0,3)
(2,0)
from (0,3) we know that the b in the equation is 3
now to calculate m or slope we use
= -3/2
so we plug our m and b into y = mx + b and get
y = -3/2x + 3
