68 ÷ 170 = 0.4
0.4 * 100 = 40
68 of 170 = 40%
393 ÷ 60% = ?
60% ÷ 100 = 0.6
393 ÷ 0.6 = 655
393 is 60% of 655

Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
Answer:
Step-by-step explanation:
One
<em>Part A</em>
5, -3*5, (-3)^2 * 5, (-3)^3*5, (-3)^4 * 5
5, - 15, 45, -135, 405
<em>Part B</em>
Second term = -15
Fourth term = -135
The difference = -15 - (-135) = 120
Two
(4 + 2)*(6-2)/(-1)
(8/2) * (5 + 1) * (2 - 1)/(-1)
(16/4) * (3+3) * (2 -1) / (- 1)
(30 - 6) * (0 + 1) / - 1
Answer:
Step-by-step explanation:
Given function,
Step 1 : Replace g(x) by y:
Step 2 : Swap x and y:
Step 3 : Solve the equation for y ( isolate y in the left side ):
Step 4: Replace y by :
Hence, the inverse of the function g(x) is .
