Answer:
f⁻¹(7) = 1
Step-by-step explanation:
Step 1: Write out function
f(x) = 3x + 4
Step 2: Find f⁻¹(x) (or known as inverse f(x))
y = 3x + 4
x = 3y + 4
-3y + x = 4
-3y = 4 - x
y = -4/3 + x/3
Step 3: Plug in 7 into inverse f(x)
f⁻¹(7) = 7/3 - 4/3
f⁻¹(7) = 3/3
f⁻¹(7) = 1
The angle between sides GM and MT is ∠M.
The 2 sides that include ∠T are MT and GT.
The angle between sides GT and MG is ∠G.
There's not much to say about this, but I can answer questions if you have any.
Yes. B/c as long as it has the same variable, you can add them, subtract, or anything else to them. As long as they have the same variable in common.
Hope this helps (:
Answer:
c. -1
b. 5
Step-by-step explanation:
x^2 - 4x - 5 = 0
Factor
What two numbers multiply to -5 and add to -1
-5*1 = -5
-5+1 = -4
(x-5) (x+1) =0
Using the zero product property
x-5 =0 x+1 =0
x=5 x=-1
