a car rental company charges an initial fee plus a constant fee per kilometer driven this table compares a total distance driven
ollegr [7]

Answer:

$120

Step-by-step explanation:

The initial fee that was charged is the y-intercept of the equation that represents the situation given.

Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.

Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.

First, using two pairs, (105, 183) and (140, 204), find the slope (m):

m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{204 - 183}{140 - 105} = \frac{21}{35} = \frac{3}{5}

m = ⅗

To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into y = mx + b.

183 = \frac{3}{5}(105) + b

183 = 63 + b

Subtract 63 from each side

183 - 63 = b

120 = b

The initial fee of the company is $120.

PLEASE HELP !!! ONLY AN HOUR LEFT
kolbaska11 [484]

Answer: arc ef is 68

Step-by-step explanation:

Since EF and FG are the same length (given)

and DE and DG are the same length (both are radius of the circle)

and DF is a shared side, the 2 inscribed triangles are congruent, making angle EDF also 68

The measure of an arc is the same as the measure of the angle across from it
