Answer:
Step-by-step explanation:
Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}
This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2
However we must double the values to get back to the original list. So the rule is y = 2*x^2
What she should do:
1ft = 12 in.
12 in - .5 = 11.5 in.
How much more she needs to mark:
11.5 inches
X+y=30
2x-3y=5
y=30-x
2x-3(30-x)=30
2x-90+3x=30
5x=120
x=24
y=30-x
y=30-24
y=6
The positive difference between the two numbers is 18.
Answer:
$1,020
Step-by-step explanation:
0.06x + 0.16(20,000 - x) = 1500
