Answer:
A'(-4, -2), B'(4, -7), C'(5, -1)
Step-by-step explanation:
Reflection in the x-axis changes the sign of each y-coordinate.
(x, y) ⇒ (x, -y)
A(-4, 2) ⇒ A'(-4, -2)
B(4, 7) ⇒ B'(4, -7)
C(5, 1) ⇒ C'(5, -1)
Answer:
y = 0.75x + 12
Step-by-step explanation:
The estimated total cost, y, of a child's toy is partially based on the number 1 point of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?
y = 12x + 0.75
y = 0.75x + 12
y = 12x − (775
y = 0.75x − 12
y = total cost of a child's toy
Cost of each battery = $0.75
Number of batteries = x
Cost of the toy = $12
Therefore,
total cost of a child's toy = Cost of the toy + Cost of each battery * Number of batteries
y = 12 + 0.75 * x
y = 12 + 0.75x
y = 0.75x + 12
Answer:
2.5 pie/person
Step-by-step explanation:
(5 pie)/(2 person) = (5/2) pie/person = 2.5 pie/person
Answer:
32 minutes
Step-by-step explanation:
This can be calculated with some good old division and multiplication:
Step 1 - Divide the word count by the number of words every 2 minutes:
2000 ÷ 125 = 16
Step 2 - Multiply the 16 by the 2 minutes:
16 * 2 = 32
The 16 is the number of words it would take and multiply the 16 by 2 will tell us the number of minutes it would take for the whole document to be written.
So it would take him 32 minutes.
Hope this helps!
