Answer:

The work shown is not correct.

The subtraction sign did not get distributed to the –10i.

The sign on –10i should have changed.

The imaginary part should be 12i.

Sample response: The work shown is not correct. When the distributive property was used, the -10i should have changed to +10i, making the sum 8+12i.

Find f(x) if it is known that f(2a−1)=7a−13.
sattari [20]

Answer:

f(x)=3.5x-9.5

Step-by-step explanation:

Given:

The given function in terms of 'a' is given as:

f(2a-1)=7a-13

In order to determine f(x), we need to make 2a-1 equal to 'x' and find the value of 'a'. Therefore,

2a-1=x\\2a=x+1\\a=\frac{x+1}{2}

Now, plug in the value of 'a' on both sides, we get:

f(2\frac{x+1}{2}-1)=7\frac{(x+1)}{2}-13\\f(x+1-1)=3.5(x+1)-13\\f(x)=3.5x+3.5-13\\f(x)=3.5x-9.5

Therefore, the expression for the function in terms of 'x' is:

f(x)=3.5x-9.5

Annabelle and Navene are multiplying (4275)(4372). Annabelle's Work Navene's Work (4275)(4372) = 42 + 375 + 2 = 4577 (4275)(4372
natta225 [31]

Neither are correct.

Navene has broken the problem up and simply added numbers together to get "4577"

Annabelle is also wrong because whereas she multiplied, she also broke up the numbers in the equation to get "46710"

The answer should be 18,690,300
