A student ID number is a letter of the alphabet followed by 2 digits. How many different IDs are possible if the digits can be r
mars1129 [50]
First, there are 26 distinct alphabets and 10 distinct digit numbers.

Then, the first digit of ID has 26 possibilities.

For the rest of 2 digits, the total cases are 10*10 = 100 possibilities.

However, there are 10 cases are repeated when two digits are the same. so you have  to subtract it by 10

So answer will be 26 * (100-10) = 23400

I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.

Choose the equations which have a greater rate of change than the graph.
NemiM [27]

Option C: y=\frac{3}{10} x is the equation that have a greater rate of change.

Explanation:

From the graph the coordinates are (0,0), (20,6), (40,12), (60,18) and (100,30)

We need to determine the rate of change.

The rate of change can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the any two coordinates in the formula, we get, the slope of the equation.

Let us substitute the coordinates (20,6) and (100,30)

Thus, we have,

m=\frac{30-6}{100-20}

Simplifying, we get,

m=\frac{24}{80}

Dividing, we get,

m=\frac{3}{10}

Also, the y - intercept of the equation is b=0

The equation of the line becomes y=\frac{3}{10} x

Thus, the equation that has a greater rate of change is y=\frac{3}{10} x

Hence, Option C is the correct answer.

Solve the system of equations by using the substitution method.<br><br> 3x - 5y = 17<br> y=x-5
Karolina [17]

Answer:

x= 4, y= -1

Step-by-step explanation:

3x -5y= 17 -----(1)

y= x -5 -----(2)

Substitute (2) into (1):

3x -5(x -5)= 17

Expand:

3x -5x +25= 17

-2x= 17 -25

-2x= -8

x= -8 ÷(-2)

x= 4

Substitute x= 4 into (2):

y= 4 -5

y= -1
