Answer:
2√5
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
= √[1 - (-1)]² + [3 - (-1)]
= √(2)² + (4)²
= √(4) + (16)
= √20
= 2√5
Answer:
The slope is 1/5= rise/run
and y-intercepts is -1
Step-by-step
First, let's move combine like terms:
-5y + 8y = 6 + 2 -12.
3y = -4.
y = -4/3
Answer:
the x is the independent variable so the guests the y is the dependent variable so the cost.
Step-by-step explanation:
because so when there are 100 people there is 4,200 +750 and the cost is 4,950
