Answer:

y=2x + 5 I think it should be

C. g(x) = x - 3

Step-by-step explanation:

The given function is

$f(x)=x$

When we transform a parent function, we can translate it, rotate it, stretch it or expand it. However, in this case, the problem is asking for translations.

If we want to translate the function downside, we just have to subtract units from f(x), like this f(x) - u.

If we want to translate the function horizontally, we have to add or subtract units to the x-variable of the function.

So, in this case, to move the parent function 3 units down, we have to subtract 3 units.

Therefore, the transformation would be

$g(x) = x-3$

So, the right answer is C.

Answer:

g(x)=x-3

where is the mistake and what should be done differently?

Answers

Step-by-step explanation:

a) There's a mistake at the third step from the beginning.

b) Instead of adding 25 , Josh added 100. While solving an equation using "Completing Squares Method" , we need to write the L.H.S. in the form of $a^(2) + 2ab + b^(2)$ or $a^(2) - 2ab + b^(2)$ , so that in the next step it can be converted into $(a + b)^(2)$ or $(a - b)^(2)$ .

c) $x^(2) + 10x - 88 = 8$

Taking -88 to R.H.S. , it's sign changes and becomes +88.

$=> x^2 + 10x = 88 + 8 = 96$

Using "Completing Squares Method" , L.H.S. can be written as :-

$(x)^(2) + 2 * x * 5 + (5)^(2) = 96 + (5)^(2)$

$=> (x + 5)^(2) = 96 + 25 = 121$

$=> x + 5 = √(121) = -11 \: or +11$

$=> x = +6 \: or -16$

Ellen Saver went to her bank. She had a balance of $2,447.67 in her savings account. She withdrew $231.49 and the teller credited her account with $36.61. What is her new balance?

Answers

Answer:

$2,252.79

Step-by-step explanation:

To answer the question, we use the formula to calculate the balance:

Balance = initial balance - withdrawal + credited amount

Initial balance = $2,447.67

Withdrawal = $231.49

Credited amount = $33.61

Substituting the variables for their values, we have

Balance = $2,447.67 - $231.49 + $33.61

Balance = $2,252.79

In conclusion, Ellen's new balance in her bank account is $2,252.79

--------------------------------------------------------------------------------------------------

I hope this helps!

$2,447.67 - $231.49 = $2,216.18

$2,216.18 + $36.61 = $2,252.79

her new balance is $2,252.79
