Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
Answer:
<h2>Option A</h2>
Step-by-step explanation:
<h3>To round to ONE decimal place means one significant number should be after the decimal point (.)</h3><h3>Option A is the correct answer because if I a zero leads after the decimal point then it isn't significant.</h3><h3>The zero in option A is insignificant but other numbers are and it says to ONE decimal place so option A is the correct answer.</h3><h3>Hope this helps.</h3>
Good luck ✅.
The true statement is Peter walks at a rate of 13 over 4 miles per hour.
<h3>What is the true statement?
</h3>
Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases. When the hour Peter walks increases, the distance he walks also increases.
Here are the options:
Peter walks at a rate of StartFraction 4 over 13 EndFraction miles per hour.
Peter walks at a rate of 4 miles per hour.
Peter walks at a rate of StartFraction 13 over 4 EndFraction miles per hour.
Peter walks at a rate of 13 miles per hour.

Answer:
B. All real numbers
Step-by-step explanation:
2(x + 1) = 2x + 2
Distribute the 2 inside the parenthesis.
2x + 2 = 2x + 2
Since the two expressions are equal and will stay equal with any value, the answer to this question is All real numbers.
Example:
2(x + 1) = 2x + 2
2(5 + 1) = 2(5) + 2
2(6) = 10 + 2
12 = 12
2(x + 1) = 2x + 2
2(150 + 1) = 2(150) + 2
2(151) = 300 + 2
302 = 302
The expression is equal for any value put in x.
Answer:
x =0,1,2,3,4,5,6
P(x) =0,4,8,12,16,20,24
Step-by-step explanation:
P(x)= 4x
4 x 1 = 4
4 x 2 = 8
4 x 3 =12
4 x 4 = 16
4 x 5 = 20
4 x 6 = 24
