Answer:
The answer is 4
Step-by-step explanation:
Remove the parentheses
55d + 35 + 15d = 315
Collect the like terms
70d + 35 = 315
Move the constant to the right
70d = 315 - 35
Subtract the numbers
70d = 280
d = 4

Answer:
The last graph
Step-by-step explanation:
You have to solve for n that is where you get the plot then you have to remember in inequalities if you divide by a negative you have to switch the sign. The inequality is not a less than or equal to or greater than or equal to so the plot would be an open circle. Because we switched the sign it goes down the left side of the graph because of the direction the sign is pointing to.
Answer:
Step-by-step explanation:
4x + 3y = 24
4x - y = 8
4x + 3y = 24
-4x + y = -8
4y = 16
y = 4
4x - 4 = 8
4x = 12
x = 3
(3, 4)
