The answer should be 1. Reflection over the x-axis and shifted 3 units to the left.

Answer:

Option A is the answer

Step-by-step explanation:

Here f(x) =-4^x

in order to change the sign in front ,we need to  reflex it with respect to x axis

and since here 3 is added to x  [ as its x+3 in place of x ] which means  it change in x  which gives 3 units to the left.

  Option A is the answer.

Paul wants a bike that cost $400. If he had saved 60% of this amount, how much had he saved.
enyata [817]
Hey!


To solve this problem, we'll first start by creating an equation.

<em>Our Created Equation :
</em>
\frac{400 x 60}{100}

Now we'll solve it step by step to find the answer.

So we should begin by multiplying the to portion of our fraction.

<em>400 x 60 = 24,000</em>

Next, we divide our answer by 100, since that is the next step to our equation.

<em>24,000 ÷ 100 = 240</em>

So, our answer is...

<em>Paul has already saved</em>  $240.00  <em>of the $400.00 he must pay for a new bike.</em>

Hope this helps!

Answer:

  (a, b) = (-2, -1)

Step-by-step explanation:

The transpose of the given matrix is ...

  A^T=\left[\begin{array}{ccc}1&2&a\\2&1&2\\2&-2&b\end{array}\right]

Then the [3,1] term of the product is ...

  (A\cdot A^T)_{31}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}1&2&2\end{array}\right]=a+2b+4

and the [3,2] term is ...

  (A\cdot A^T)_{32}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}2&1&-2\end{array}\right]=2a-2b+2

Both of these terms in the product matrix are 0. We can solve the system of equations by adding these two terms:

  (a +2b +4) +(2a -2b +2) = (0) +(0)

  3a +6 = 0

  a = -2

Substituting for 'a' in term [3,1] gives ...

  -2 +2b +4 = 0

  b = -1

The ordered pair (a, b) is (-2, -1).
