Answer:
The correct answer is 1
Step-by-step explanation:
The composite function g(f(x)) will be given by;
(1+x)^2 -(1+x)
Substituting x with zero yields g(f(0)) =0.
On the other hand, the composite function f(g(t)) will be given by;
1+t^2-t
Substituting t with zero yields f(g(0)) =1
Finally, g(f(0)) + f(g(0)) =0+1 = 1.
Required polynomial is (x - 4)(x + 5)(x - 7) = (x - 4)(x^2 - 2x - 35) = x(x^2 - 2x - 35) - 4(x^2 - 2x - 35) = (x^3 - 2x^2 - 35x) - (4x^2 - 8x - 140) = x^3 - 2x^2 - 35x - 4x^2 + 8x + 140 = x^3 - 6x^2 - 27x + 140
7 1/5 = 36/5
6 2/5 = 32/5
36/5 - 32/5 = 4/5
a. 4/5
Answer:
Should have worked out brackets first then kept it to two subtractions (one being negative number total and the other being positive total number at step 3 ) taking you to step 4 as finish to just add the two numbers a( - 5.3) + (5.5) = 0.2
Step-by-step explanation:
(3.9 − 9.4) − 0.6 + 6.1. To simplify do brackets first so the first error was Step 2 line we show (3.9 − 9.4)− 0.6 + 6.1 below = to (-5 .3) − 0.6 + 6.1 Then to simplify Step 3 line there was a second error as 3.9 was never a simplification of the brackets and here is how it should be ( - 5.3) − 0.6 + 6.1 = ( - 5.3) + (5.5) = ( - 5.3) + (5.5) Then to simplify Step 4 line we wont need a step 5 and are left to just add the two numbers ( - 5.3) + (5.5) = 0.2
I think its either 1% or 2%
