<em>Complete Question:</em>
<em>Alicia is writing the program for a video game. For one part of the game she uses the rule (x,y)->(x-3,y+4) to move points on the screen. </em>
<em>A) what output does the rule give when the input is (-6,0)? </em>
<em>B)What output does the rule give when the input is (3,-4)? </em>
<em>C) Is the rule a function? Explain why it is or why it is not
</em>
Answer:
a. The output is (-9,4)
b. The output is (0,0)
c. See Explanation
Step-by-step explanation:
Given
Rule: (x,y)->(x - 3, y + 4)
Solving (a):
Inputs:
The outputs is as follows;
Hence:
The output is (-9,4)
Solving (b):
Inputs:
The outputs is as follows;
Hence:
The output is (0,0)
Solving (c):
The function is a rule and the rule is that:
It shifts the graph left by 3 units and up by 4 units
I'm assuming you meant 62p=610. If this is the case, then p = 610/62, or 9.84.
This does not match any of the four answer choices.
I'd suggest you ensure that you have copied down this problem completely and accurately.
Answer:
Audrey can afford 4 hours of lesson.
Step-by-step explanation:
Given that:
Amount Audrey has to spend = $111
Cost of racket = $55
Cost per lesson = $14
Let,
y be the total cost
x be the number of hours
According to given statement;
y = 14x + 55
111 = 14x + 55
111 - 55 = 14x
14x = 56
Dividing both sides by 14
Hence,
Audrey can afford 4 hours of lesson.
From the given equations below,
(1) 6x + 6y = 7.50
(2) 10x + 5y = 8.75
Solving for the values of x and y simultaneously gives an answer of x = 0.5 and y = 0.75.
Thus, the cost of apples and oranges are $0.5 and $0.75, respectively.
