Answer:
(0, 32)
Step-by-step explanation:
The function hits the vertical line (y-axis) at it's 32 mark, and 0 is always the first coordinate of a y-intercept, so it's (0, 32).
Answer:
The required expression is 
Step-by-step explanation:
Given : Expression 'Nine less than the quotient of two and a number x'.
To find : Write the expression ?
Solution :
Writing the expression from word form to numerical form,
The quotient of two and a number x is represented as 
Nine less than the quotient of two and a number x is represented as
Therefore, The required expression is
We are given the total earnings of the school, $2800.
The earnings of each grade level are as follows:
2nd grade = $200
5th grade = $200
kindergarten = 2 * $200 = $400
4th grade = 2 * $200 = $400
1st grade = 3rd grade = x
The amount which is left for us to determine is the earnings of the first and third grade. This can be determined by equating all earnings to the total school earnings and let 1st and 3rd grade be the variable x:
$2800 = $200 + $200 + $400 + $400 + x + x
$2800 = $1200 + 2x
$1600 = 2x
x = $800
Therefore, 1st grade and 3rd grade earned $800 each. <span />
