Answer:
y = ±√(x-16)
Step-by-step explanation:
To find the inverse of an equation, swap the x- and y-variables:
y = x² + 16
x = y² + 16
Then, solve for the y-variable:
x = y² + 16
y² = x - 16
y = ±√(x-16)
Answer:
13 batches of cookies
Step-by-step explanation:
12 2/3 ÷ 2/3 = 12.6666667, it's 13 because 2/3 as a decimal is .6666666 and .6666667 is more than 2/3. So you add one to the answer.
X4 hm I’m pretty sure that’s it
Answer:
4/5
Step-by-step explanation:
In a right triangle such as this one
cos (angle) = adjacent leg / hypotenuse
cos(k) = KL / 15
You will need to find the leg length KL using Pythagorean Theorem
15^2 = 9^2 + (KL)^2 KL = 12
then cos k = 12/15 = 4/5
