To find that , divide the estimate by the actual weight and multiply by 100.
8/6*100=133.33%(rounded)
Therefore the percent error is 133.33%.
Answer:
x= -1/4 , -.25,
Step-by-step explanation:
move terms, collect the like terms, calculate, divide both sides by 4
For this case we must write a number of the form:
Where,
a: power base
b: exponent of the power
We must write a power that complies with the following inequality:
Substituting values we have, for example:
Answer:
a power represented with a positive base and a positive exponent whose value is less than the base is:
First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1
</span>
Answer:
y = 3x
Step-by-step explanation:
x is number of cartons of eggs
y is cost
cost increases by 3 for every carton of eggs, so slope is 3
x and y intercepts are zero because there is no cost when there are no eggs
equation: y = 3x
