Answer:
y = 80-16x
Step-by-step explanation:
She made a total of 80 cups and sells 16 cups per hour
So in x hours she would have sold 16 * x = 16x cups
So the number of cups remaining will be;
y = 80-16x
Answer:
Reflection over the x-axis
Step-by-step explanation:
The transformation rule for a reflection over the x-axis is (x, -y)
Answer:
(5, -1)
Step-by-step explanation:
x + y = 4
x - y = 6
Add the equations to eliminate y
2x = 10----> x=5
Substitute this value in any equation
5 + y = 4 ----> y = 4-5 ----> y= -1
64 : [4 x ( 27 - 5²)
= 64 : [ 4 x ( 27 - 25)
= 64 : ( 4 x 2)
= 64 : 8 = 8
5² = 5 x 5 = 25
50.64 - [4 x ( 27 - 5²)] = 50.64 - 4 ( 27 - 25) = 50.64 - 4 x 2 = 50.64 - 8 = 42.64
