According to his answer above, the factor is (a+8)(a-3). To solve for a, we could see what can give 0 when we multiply the factor. In (a-3), 3 can be subtracted by 3 which is 0, then is being multiplied by another factor, which is still 0. So let's plug 3 as a in our equation. 3^2+5(3)-24=0 is 9+15-24. Simplify. 9+15-24 is 0, so 3 can be an answer to our equation. Now let's see what can we add in (a+8) to get 0. That is -8, because -8+8=0. Now let's try in our equation. -8^2+5(8)-24 is 64+40-24. Simplify. 84-24 which is 60. So -8 can not be a possibility. Therefore 3 is the only answer.

Real answer: a=3

(a + 8)(a - 3)
You should think about what numbers multiply together to give -24 but add together to give you +5.

The parent function is f(x) = 2^x-6 + 3 and the new function is g(x) = 2^x-3 + 2

Greeley [361]

Answer:

Options C and D.

Step-by-step explanation:

The given functions are

$f(x)=2^{x-6}+3$

$g(x)=2^{x-3}+2$

We need to find the transformation from f(x) to g(x).

Now, write the function g(x) in the form of f(x).

$g(x)=2^{x+3-3-3}+2+1-1$

$g(x)=[2^{(x+3)-6}+3]-1$

$g(x)=f(x+3)-1$ ...(1)

The translation is defined as

$g(x)=f(x+a)+b$ .... (2)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (1) and (2), we get

$a=3>0$ , so graph shifts 3 units left.

$b=-1$ , so graph shifts 1 unit down.

Therefore, the correct options are C and D.

Answer: 16875

Step-by-step explanation:

Let the price of the washing machine be x.

Since she loses 20% in the bargain, this implies that she sold it at (100% - 20%) = 80%.

Therefore, 80% of x = 13500

0.8 × x = 13500

0.8x = 13500

Divide both side by 0.8

0.8x/0.8 = 13500/0.8

x = 16875

Therefore, the price at which she bought the washing machine is 16875 rupees.
