So the rule with 270° counterclockwise rotation is the same as 90° clockwise rotation: <u>(x,y) → (y,-x)</u>

Now applying this rule to this coordinate,<u> (-5,1) would become (1,5).</u>

I need help with question number 2 and 3. But 2 if I can only get help with one question.

Number 2:

To solve the quadratic equation by using the factorization method;

$x^2-6x+8=0$

We note here that the factors of 8 that can also add up to -6 are -4 and -2.

Therefore we'll have;

$\begin{gathered} x^2-4x-2x+8=0 \\ (x^2-4x)-(2x+8)=0_{} \\ x(x-4)-2(x-4)=0 \\ \text{Collect like terms and we'll have;} \\ (x-4)(x-2)=0 \end{gathered}$

Therefore, we now have;

$\begin{gathered} x-4=0,x-2=0 \\ x=4,x=2 \end{gathered}$

To solve the quadratic equation by using the quadratic equation formula, we would have;

$\begin{gathered} x^2-6x+8=0 \\ \text{The formula is;} \\ x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ \text{Where;} \\ a=1,b=-6,c=8 \\ x=\frac{-\lbrack-6\rbrack\pm\sqrt[]{(-6^2)-4(1)(8)}}{2(1)} \\ x=\frac{6\pm\sqrt[]{36-32}}{2} \\ x=\frac{6\pm\sqrt[]{4}}{2} \\ x=\frac{6\pm2}{2} \\ \text{Hence, we now have;} \\ x=\frac{6+2}{2},x=\frac{6-2}{2} \\ x=\frac{8}{2},x=\frac{4}{2} \\ x=4,x=2 \end{gathered}$

Therefore, using the quadratic equation formula, we also have;

$x=4,x=2$

In an American Sign Language (A.S.L) class of 26 students, 15 are hearing impaired. What fraction of the students are hearing

postnew [5]

The best way to get this answer would be to divide 15 by 26, getting 0.576923077, then multiplying that number by 100, getting 57.6923077, then you round it to the nearest whole number if needed. The answer to the nearest whole number is 58%.
