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
Answer:
No solution
Step-by-step explanation:
we have
Apply distributive property left side
subtract 2x both sides
------> is not true
therefore
The system has no solution (two parallel lines)
I am gonna go with graph B...simply because I know it is a positive slope...but it is not linear
Answer:
p = 8
Step-by-step explanation:
17 = 3 ( p - 5 ) + 8
Distribute
17 = 3p - 15 + 8
Simplify
17 = 3p - 7
Inverse operations
17 = 3p - 7
+7 +7
24 = 3p
/3 /3
8 = p
Answer:
3
Step-by-step explanation:
-(x-4)+5=3x+6-x(BODMAS)
-x+4+5=3x+6-x(collect like terms )
4+5=3x+x-x
9=3x (divide both sides by 3)
9/3=3x/3
3=x
