Answer: None of those are functions
Step-by-step explanation: They all fail the vertical line test. x values do not repeat. Those intersect more than one pint on the relationship if you were to take a line and move it across the graph.
Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
Answer:
18/30
Step-by-step explanation:
He has been out of town 18 out of the 30 days. You can simplify this to 6/10.
It is -5/8x (the slash represents a fraction sign)
Answer: B 192
Step-by-step explanation: In the picture attached, the complete question is shown.
The humpback whale traveled 2240 miles in 28 days. This makes the following rate:
rate = distance/time = 2240/28 = 80 miles/day
The distance traveled at this rate in 32 days is:
distance = rate * time = 80*32 = 2560 miles
The gray whales traveled 2368 miles in 32 days. Then, the humpback whales would have traveled 2560 - 2368 = 192 miles more than the gray whales.
