Answer:
25 choices
Step-by-step explanation:
Given
Possible Combinations: 1 to 25
Selections: 3 numbers
Required
Determine the number of choices of the first number
The first number of the lock can be any of 1 to 25.
This is so because when you counting from 1 to 25, there are 25 numbers
<em>Hence, number of choices is 25 numbers</em>
Answer:
y = 3 and x = - 6
Step-by-step explanation:
y + 4 = 0 ( subtract 4 from both sides )
y = - 4
this is the equation of a horizontal line, parallel to the x- axis.
a parallel line will also be horizontal with equation
y = c ( c is the value of the y- coordinates the line passes through )
the line passes through (- 6, 3 ) with y- coordinate 3 , then
y = 3 ← equation of parallel line
a line perpendicular to the given line will be a vertical line with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (- 6, 3 ) with x- coordinate - 6 , then
x = - 6 ← equation of perpendicular line
