Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
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:
4.0833333333333333333333333333333333
Step-by-step explanation:
You need to add all the numbers up together 3,4,8,5,2,5, and even 0,5,3,4,3,7
then you get 49 and then you have to divided by how many numbers there are in this case we have 12 numbers including 0 and you get your answer 4.083 repeating so its just going to be 4.083333333333333333333333
Answer:
a = b/4
Step-by-step explanation:
Note that the LCD in this equation is 6. Rewriting 2a-b/6 = b/3 using this LCD, we get:
2a-b/6 = 2b/6
Multiplying all three terms by 6 eliminates the fractions:
12a - b = 2b
Combining like terms:
12a = 3b
3b
Solving this for a, we get a = ------------ = b/4
12
a = b/4
