Answer:
The positive zero is 11
Step-by-step explanation:
Given in the question an equation,
f(x) =x² - 121
We are asked to find the positive zero of f(x)
means x > 0 for which f(x) = 0
so,
<h3> x² - 121 = 0</h3>
x² = 121
Take square root on both sides of the equation
√x² = √121
x = ±11
which means that x = 11 and x = -11
Since x > 0 so we will reject x =-11 and we will accept x = 11
They’re equivalent because 3 • 3 is 9 and whatever you do to the top, you do to the bottom, therefore 4 • 3 is 12. That would equal 9/12.
Answer:
a. y = -x
b. Area = xy
c. x = -y
Step-by-step explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y
