Answer:
f^-1(x) = x + 5
Step-by-step explanation:
f(x) = x-5
y = x-5
Exchange x and y
x = y-5
Solve for y
x+5 = y-5+5
x+5 =y
The inverse is x+5
Answer:
35% of 800
35% = 0.35
0.35 × 800 = 280
Your answer is 280 tickets ; 0.35 × 800
Answer: x2 + 34x - 13
Step-by-step explanation:
STEP
1
Trying to factor by splitting the middle term
1.1 Factoring x2+34x-13
The first term is, x2 its coefficient is 1 .
The middle term is, +34x its coefficient is 34 .
The last term, "the constant", is -13
Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13
Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .
-13 + 1 = -12
-1 + 13 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 + 34x - 13
Answer:
18.84
Step-by-step explanation:
c=2×3.14(pi) × 6(diameter)/2
c=2×3.14×6/2
c=18.84
Answer:
x = 67.5 ft.
Step-by-step explanation:
The triangles MBA and MPN are similar.
So corresponding sides are in the same ratio.
Therefore x / 97.5 = (71.5 - 22) / 71.5
x / 97.5 = 49.5 / 71.5
x = 49.5 * 97.5 / 71.5
x = 67.5 ft,
