Answer:

$21^{10}$

Step-by-step explanation:

First, multiply the 3 and the 7 together, and then "multiply" the exponents -8 and 3. (However, when "multiplying exponents, you're really just adding them together: -8 + 5)

( $21^{-5}$ )^2

Then, multiply the -5 and -2 together, giving you:

$21^{10}$

The graph of a line passes through the points (0, -2) and (6.0). What is

9966 [12]

Answer:

$y=\frac{1}{3}x-2$

Step-by-step explanation:

The equation of a line is given in the form $y=mx+b$

Where

m is the slope with formula $m=\frac{y_2-y_1}{x_2-x_1}$

and

b is the y-intercept [y axis cutting point of line]

Given the two points (0, -2) and (6,0),

x_1 = 0

y_1 = -2

x_2 = 6

y_2 = 0

Now, we find m using formula:

$m=\frac{0+2}{6-0}=\frac{1}{3}$

Now we have

$y=\frac{1}{3}x+b$

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

$y=\frac{1}{3}x+b\\0=\frac{1}{3}(6)+b\\0=2+b\\b=-2$

Thus,

equation of line = $y=\frac{1}{3}x-2$

The annual fixed costs of owning a small sedan are $4407, assuming the car is completely paid for. The cost to drive the car is

vodomira [7]

Answer:

y(Cost)=.17x(x=miles)+4407

y=.17x+4407

Step-by-step explanation:

The cost of the vehicle is 4407$ fixed, with .17$ per mile. A liner equation, y=mx+b can be substituted with m being the cost per mile and 4407$ being the fixed annual value. Y is the total Cost of everything.
