Answer:

78,624,000 license plates

Step-by-step explanation:

For each of the 4 numbers, we have the following possibilities:

First number: 10 digits possible

Second number: 9 digits possible (one used)

Third number: 8 digits possible (two used)

Fourth number: 7 digits possible (three used)

For each of the 3 letters, we have the following possibilities:

First letter: 26 digits possible

Second letter: 25 digits possible (one used)

Third letter: 24 digits possible (two used)

The total number of license plates is the product of all these possibilities:

Number of plates = 10 * 9 * 8 * 7 * 26 * 25 * 24 = 78,624,000 license plates

lozanna [386]

Answer:

3) 5.4

Step-by-step explanation:

Given two points (x1, f(x1)) and (x2, f(x2)), the average rate of change is computed as follows:

[f(x2) - f(x1)]/[x2 - x1]

From the original photograph to the fourth enlargement, the points are (0, 15) and (4, 36.6). Replacing into the equation we get:

[36.6 - 15]/[4 - 0] = 5.4

What is the y-value of the solution to the system of equations? 3x + 5y = 1 7x + 4y = −13
brilliants [131]
3x + 5y = 1 . . . . . . . . (1)
7x + 4y = -13 . . . . . . .(2)
(1) x 7: 21x + 35y = 7 . . (3)
(2) x 3: 21x + 12y = -39 .(4)
(3) - (4) = 23y = 46
y = 46/23 = 2
