Answer:
78/5
Step-by-step explanation:
(15 x 5 + 3)/5
78/5
Answer:
4
Step-by-step explanation:
Step 1: Write out expression
(3x + 8) - (2x + 7)
Step 2: Distribute negative
3x + 8 - 2x - 7
Step 3: Combine like terms
x + 1
Step 4: Substitute
3 + 1 = 4
Answer:
The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.
Step-by-step explanation:
Answer:
z = 15/30 = 3/6
Step-by-step explanation:
1/5z - 5/6 = - 4/5z - 1/3
1/5z + 4/5z = - 1/3 + 5/6
5/5z = - 2/6 + 5/6
5/5z = 3/6
z = 3/6 / 5/5
z = 3/6 * 5/5
z = 15/30
slope = change in y / change is x
slope = rise / run
change in y = -1 (goes down 1)
change is x = 4 (goes right 4)
slope = -1/4
y-intercept, when x = 0
y-intercept = 1 = (0,1)
