The answer would be 150
To solve this do 50x30 and you would get 150
Answer:
Step-by-step explanation:
Calculate the length using the distance formula
• d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(0, 6) and (x₂, y₂ ) = B(7, 0)
AB =
=
= =
Answer: B
Step-by-step explanation:
To solve this problem, we first need to find the inverse of f(x). Then, you would plug in x=8. To find teh inverse, you switch y with x and x with y, then solve for y.
y=2x+5 [switch y with x and x with y]
x=2y+5 [subtract both sides by 5]
x-5=2y [divide both sides by 2]
y=(x-5)/2
Now that we have the inverse function, we plug in x=8 and solve.
y=(8-5)/2 [subtract]
y=3/2
Now, we know that f⁻¹(8)=3/2.
You were close it's actually 7/20. There's no way to simplify it as for 7 is a prime number.
