Kelly runs a distance of 100 metres in a time of 10.52 seconds.

10 raised to the first power,
so indeed.

d(-3 + x) = kx + 9

• Distribute d within the parentheses:

-3d + dx = kx + 9

• Subtract kx from both sides:

-3d + dx - kx = 9

• Add 3d to both sides:

dx - kx = 9 + 3d

• Factor x from dx - kx:

x(d - k) = 9 + 3d

• Divide both sides by (d - k):

x =

• To further simplify, factor 3 out of the numerator.

x =

Answer:

Assuming the null hypothesis—indicating there is no discrepancy between the cell phone expenses of in-state versus out-of-state individuals.

Step-by-step explanation:

Answer:

M(5,2)

Step-by-step explanation:

We apply the midpoint formula:

The arithmetic average of the x and y coordinates is needed.

The coordinates for points C and D are C(3,−5) and D(7, 9).

By substituting these values, we obtain:

Thus, the midpoint coordinates M of segment CD are (5,2)

The initial height of 5 feet above sea level serves as the y-intercept, and the erosion rate of −1 foot per 20 years represents the slope. The dune’s height y varies with time. Using the slope–intercept form gives: Y = (-1/20)t + 5
