Q1) 4a + 7b +5a - b Q2) 6c + 4d - c - 7 d

mel-nik [20]

Answer:

4a+5a+7b-b

the first thing is to put the like terms together

Step-by-step explanation:

then add or subtract as given after pairing.

Therefore;

our answer is; 9a+6b

since it is factorisable we can further write it this way; 3(3a+2b)

q2) 6c+4d-c-7d

we first put the like terms together

6c-c+4d-7d

we then add and subtract

5c-3d

since our answer is not factorisable we leavem;

5c-3d as our final answer

Simplify each of the following powers of i. i^99=

Scorpion4ik [409]

I= sqrt (-1)

If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i

99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd

Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i

Solve 4(8-2x)=2(7-x)

VladimirAG [237]

Answer and Step-by-step explanation:

Solve for x.

First, we divide both sides of the equation by 2.

2(8 - 2x) = 7 - x

Distribute the 2.

16 - 4x = 7 - x

Add 4x to and subtract 7 from both sides of the equation.

9 = 3x

Divide by 3 to both sides of the equation.

x = 3 <-- This is the answer.

What is the range of the function g(x)=[x]+1

Lerok [7]

Assuming [x] means the closest integer to x

Answer:

$(-\infty, \infty)$

Step-by-step explanation:

We can see that for any integer $x$ , there will always be a $[x]$ , so there will always be a $[x]+1$ . So, we don't need to worry about the domain impacting the range.

$[x]$ can be any integer from $-\infty$ to $\infty$ , and as $\infty+1=\infty$ (at least in terms of a function's range and domain), the range of $[x]+1$ is equal to the range of $[x]$ , which is $(-\infty, \infty)$ .
