The answer is m = 7.


1. (<span>13−m=2(m−4) </span>Regroup terms
2. Expand (<span>13−m=2m−<span>8)
3. </span></span>Add <span><span>m</span></span> to both sides (<span>13=2m−8+<span>m)
4. </span></span>Simplify (<span>2m−8+m</span> to <span><span><span>3m−8)
5. add 8 to both sides (13 + 8 = 3m)
6. </span></span></span>Simplify <span>13+8 to 21
7. </span>Divide both sides by <span><span>33</span></span> (21/3 = m)
8. simplify 21/3 to 7 (7 = m)
9. switch sides ( finally m = 7)

Let T:ℝ2→ℝ2 be the linear transformation that first rotates points clockwise through 45∘ (????/4 radians) and then reflects poin
Alisiya [41]

Answer:

T = \left[\begin{array}{ccc}-\frac{1}{\sqrt{2} } &\frac{1}{\sqrt{2} }\\\frac{1}{\sqrt{2} }&\frac{1}{\sqrt{2} }\end{array}\right]

Step-by-step explanation:

Let General Transformation matrix be denoted as T

Step 1: Clockwise rotation of 45 degrees

General counterclockwise rotation matrix in 2-dimension is given as

                                        R(\theta)=\left[\begin{array}{ccc}cos\theta & - sin\theta\\sin\theta&cos\theta\\\end{array}\right]

For clockwise rotation we need to insert θ as negative in the above matrix. Therefore, the resulting matrix is

                                        R(-\theta)=\left[\begin{array}{ccc}cos\theta & sin\theta\\-sin\theta&cos\theta\\\end{array}\right]

as sin(-θ) = -sin (θ) and cos(-θ) = cos (θ)

For 45 degrees

sin(45)  = \frac{1}{\sqrt{2} }   and   cos(45)  = \frac{1}{\sqrt{2} }

                                       R(-45)=\left[\begin{array}{ccc}\frac{1}{\sqrt{2} }  & \frac{1}{\sqrt{2} }\\-\frac{1}{\sqrt{2} }&\frac{1}{\sqrt{2} }\\\end{array}\right]

Step 2: Reflection through line y = x

This type of reflection maps (x,y)→(y,x)

Therefore the general matrix is

                                           R(x,y)=\left[\begin{array}{ccc}0&1\\1&0\end{array}\right]

Step 3: General Transformation Matrix

T = R(x,y) R(-θ)

                                    T=\left[\begin{array}{ccc}0&1\\1&0\end{array}\right] \left[\begin{array}{ccc}\frac{1}{\sqrt{2} }  & \frac{1}{\sqrt{2} }\\-\frac{1}{\sqrt{2} }&\frac{1}{\sqrt{2} }\\\end{array}\right]

                                           T = \left[\begin{array}{ccc}-\frac{1}{\sqrt{2} } &\frac{1}{\sqrt{2} }\\\frac{1}{\sqrt{2} }&\frac{1}{\sqrt{2} }\end{array}\right]

You earn $49 for washing 7 cars. How much do you earn for washing 4 cars?
ICE Princess25 [194]

Answer:

Step-by-step explanation:

We can use the rule of three!

We know we have the following relationship:

\frac{49}{7} = \frac{x}{4}

From here, we can solve this like any other equation:

4(\frac{49}{7}) = x\\x = 28

Therefore, you would earn $28 after washing 4 cars.

Good luck!
