A, or f(x) = 8,000(1/4)^x

8,000 is our starting number since number of half lives is our x, and at x = 0, remaining amount of substance is equal to 8,000. As we can see on the graph, the number decreases by a quarter of its original value every time. Since the number is not getting bigger, we use a fraction instead of a whole number. Finally, the exponent makes sure that it’s a quarter of the product from before.

Hope this helps!

What are the coordinates of the midpoint of the segment whose endpoints are (-4,6) and (-8,-2)
umka2103 [35]
The formula to find the midpoint of a segment is ((x1 + x2)/2,),(y1 + y2)/2).

The x coordinate of the first point is -4, and the x coordinate of the second point is -8.  The y coordinate of the first point is 6, and the y coordinate of the second point is -2.  Now, we can plug these into our formula.

((-4 + (-8))/2), (6 + (-2))/2)) = (-12/2), (4/2) = (-6, 2)

So, (-6, 2) is the midpoint of the segment.

Solve the inequality 3x - 5 < 4.
Pachacha [2.7K]

Answer:

      x < 3

Step-by-step explanation:

Since 3x - 5 < 4 then we can transpose the inequality to make x the subject of the equation:

    If 3x - 5 < 4

⇒    3x < 4 + 5

⇒       x < 9 ÷ 3

⇒       x < 3

RoseWind [281]

Answer:

No, the blinds will not fit inside a 45-inch space.

Step-by-step explanation:

No, the blinds will not fit inside a 45-inch space, because the blinds are too large.

To check;

140 cm = 56 inches

140 / 2.5 = 56

&

45 inches = 112.5 cm

45 x 2.5 = 112.5

Hope this helps!
