(6y - 11)(6y + 11) = ay
² - b |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b |add b to both sides
ay² = 36y² - 121 + b |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
Answer:
B
Step-by-step explanation:
I'm not really sure tho
Answer:
<h2>
</h2>
Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>
</h3>
where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>
</h3>
So the formula for the variation is
<h3>
</h3>
From the question
when x = 4
<h3>
</h3>
Hope this helps you
Answer:
x = 4
Step-by-step explanation:
A vertical line has an equation of the form x=constant. The constant value can be read from the graph as being 4, so the equation is ...
x = 4
_____
The relation does not pass the vertical line test. (A vertical line intersects the graph in an infinite number of points, not just 1.) So, this is <em>NOT A LINEAR FUNCTION</em>.
