If y varies inversely as x2 and y = 100 when

1 answer:

4 0

Ans: (c)

y = k/x^2

when y = 100, x = 1
100 = k/1^2
k = 100

when x = 2,
y = 100/2
= 50

(u/rachelmarrons already gave you the answer but here’s a step-by-step explanation in case you needed it haha)

How do you round $604.77 to the nearest ten dollars

Karolina [17]

Answer: $600

Step-by-step explanation:

Given that you're trying to round to the nearest tens, you should look at the ones place, in this case 4. Given that 4 is less than 5, and anything less than 5 rounds down, you should round down to $600 instead of $610.

Hope this helps!

The coordinates of point a are 30 units of x and 70 units of y. the coordinates of point b are 28 units of x and 76 units of y.

Leni [432]

The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
m = (y2-y1) / (x2-x1)
Substituting the values we have:
m = (76-70) / (28-30)
m = -3
answer:
the slope of the line between points a and b is
m = -3
