Answer:
23. -2
24. -7
25. +3
Step-by-step explanation:
5 + -3 + -4 = -2
-6 + 4 + -5 = -7
-3 + -3 + 9 = 3
Slope = (8 - 3)/(0 + 2) = 5/2
equation
y - 8 = 5/2(x - 0)
y - 8 = 5/2 x
y = 5/2 x + 8
Answer:
You can tell that quantities x and y are proportional if they are effecting each other.
Step-by-step explanation:
If two quantities are proportional that means they are dependent on each other.
- The quantities can be directly proportional and inversely proportional as well.
- If the increase in one quantity will increase the other quantity and decrease in quantity leads to the decrease in other then it is directly proportional. Like in Ohm's Law: the current and voltage are directly proportional in linear circuit while neglecting the resistance. The following expression show this direct proportional relation:
V ∝ I
- If the increase in one quantity results in the decrease of the other quantity or vice versa then these quantities are inversely proportional. Like if the people required to do a job increases then time required to complete the job will decrease or vice versa.

Answer:
275
Step-by-step explanation:
Let h represent the number of hamburgers sold. Then the number of cheeseburgers sold is h-62, and the combined total is ...
hamburgers + cheeseburgers = combined total
h + (h -62) = 488
2h = 550 . . . . . . . . add 62, collect terms
h = 275 . . . . . . . . . .divide by 2
275 hamburgers were sold on Friday.
Four times a number (4 times x since x represents unknown) is at least (<) two (2)
4x>2
divide both sides by 2
2x>1
