Answer:
<u>Percent Error</u> = -2.8%
Step-by-step explanation:
Percent error is found by the formula:
Percent error = 
- Recorded value is 44.25 m
- Original value is 45.5 m
<em> Putting it in the formula, we get:</em>
Rounded to nearest tenth of a percent: -2.8%
Answer:
The answer to your question is -5k⁶
Step-by-step explanation:
Polynomial
- z³ + 5k⁶ - (-z³ + 10k⁶)
Use law of signs for the parenthesis
- z³ + 5k⁶ + z³ - 10k⁶
Use associative property for like terms
(-z³ + z³) + (5k⁶ - 10k⁶)
Simplify like terms
(0) + (-5k⁶)
Result
-5k⁶
When we want to find the distance between two integers using the difference, the best way is to plot them on number line. And then count distance between them. For example -3 and -1. But distance can not be negative.
Answer:
x = -5 and y = 1
Step-by-step explanation:
a) 2x + 5y +5 = 0
a) 2x + 5y = -5
b) 2y = 3x + 17
b) y = 3/2x + 17/2
a) 2x + 5(3/2x + 17/2) = -5
a) 2x + 15/2x + 85/2) = -5
a) 19/2x = -5 - 85/2
a) 19/2x = -95/2
a) x = (-95/2) / (19/2)
x = -5
b) 2y = 3(-5) + 17
b) y = 2/2
y = 1
