Answer:
there both similar by using inverse operations to isolate the variable term by using addition or subtraction and multiplying or dividing to solve for the variable .
the difference is for an inequality if u multiply or divide by a negative number then u have to reverse the inequality symbol, for regular equations u don't have to do that , and for regular equations there is a equal sign and not a inequality symbol
Step-by-step explanation:
just explained it above
hope I helped ! pls mark me brainlest if I got it right thanks :)
Answer:a
Step-by-step explanation: it follows a proportional rate since on the y it goes up by 5 and on the x it goes by 1
Answer:
B. $57.00
Step-by-step explanation:
The totals add up to just under $55.00, so an overestimate would be $57.00
The answer is $542.40. To get this answer you subtract 20% from the total cost, $678. The discount is $135.60.
$678 - $135.60 = $542.40
Newton's numerical method to estimate the square root of N uses the iterative relation
x₀ = initial guess
We want to estimate the square root of 15, so N = 15.
We know that √{16) = 4, therefore let x₀ = 4 for the initial guess.
Calculate relative error after n iterations as
When the relative error is less than 0.01, we shall accept the approxmate answer.
Iteration #1:
x₁ = 0.5(x₀ + N/x₀) = 0.5(4 + 15/4) = 3.875
e₁ = |1 - 4/3.875| = 0.032
Iteration #2:
x₂ = 0.5(3.875 + 15/3.875) = 3.873
e₂ = |1 - 3.875/3.873| = 5.2 x 10⁻⁴
This is good enough.
Therefore the approximate value for √(15) is 3.873.
On a number line, the progression to find the square root is shown below.
Answer: 3.873
