Answer:

reflect across x axis: (x,-y)

reflect across y axis: (-x,y)

reflect across y=x: (y,x)

reflect across y= -x: (-y,-x)

90 cc rotation: (-y,x)

180 rotation: (-x,-y)

270 cc rotation: (y,-x)

Step-by-step explanation:

reflect across x axis: (x,-y) - x coor stays same and only y coor becomes negative

reflect across y axis: (-x,y) - x coor becomes negative and y coor stays the same

reflect across y=x: (y,x) - both coordinate switch places, no signs are changed

reflect across y= -x: (-y,-x) - both coordinates switch places and the signs are switched to the opposite sign of the original number

90 cc rotation: (-y,x) - opposite of the original y coor and both coordinates switch place (same as 270 clockwise)

180 rotation: (-x,-y) - both coordinates stay in there original place but with the opposite values of the original value

270 cc rotation: (y,-x) - both coordinates switch places and the x values is the opposite of the original value (same as 90 clockwise)

*to find the third columns answer all you have to do is plug in the given x and y values into the coordinate rule

If x- 2 is a factor of x^2 -bx+ b, where b is a constant, what is the value of b
KATRIN_1 [288]
\bf x^2-\underline{b} x+b\implies \stackrel{given}{(x-2)}~(x-y)\impliedby \textit{now let's do some FOIL}\\\\
-------------------------------\\\\
\begin{cases}
-yx-2x=-\underline{b}x\implies y+2=\underline{b}\\
(-2)(-y)=b\implies 2y=b
\end{cases}
\\\\\\
\underline{b}=b\implies y+2=2y\implies 2=y

what is b?   from the first equation in the system, y + 2 = b.

F(x)= x+3<br> h(x)= x^2+4<br><br> Find (f•h)(x)
Dmitrij [34]

Answer:

x³+3x²+4x+12

Step-by-step explanation:

you are going to write both equations and distribute. if there are like terms, combine them and then put it order.

(x + 3) × (x² + 4)

x³ + 4x + 3x² + 12

when putting in order, you want the highest power to the left and then the lowest power to the right.

so

x³+3x²+4x+12

What else would need to be congruent to show that ABC DEF by SAS? E AA. А B OA. BC = EF B. CF OC. ZA ZD D. AC = OF F Given: AC =
serg [7]

The two triangles exist congruent if they contain two congruent corresponding sides and their contained angles exist congruent.

Let $&\overline{A B} \cong \overline{D E} \\ and $&\overline{A C} \cong \overline{D F}

Angle between $\overline{A B}$ and $\overline{A C}$ exists $\angle A$.

Angle between $\overline{D E}$ and $\overline{D F}$ exists $\angle D$.

Therefore, $\triangle A B C \cong \triangle D E F$ by SAS, if $\angle A \cong \angle D$$.

<h3>What is SAS congruence property?</h3>

Given:

$&\overline{A B} \cong \overline{D E} \\ and

$&\overline{A C} \cong \overline{D F}

According to the SAS congruence property, two triangles exist congruent if they contain two congruent corresponding sides and their contained angles exist congruent.

Let $&\overline{A B} \cong \overline{D E} \\ and $&\overline{A C} \cong \overline{D F}

Angle between $\overline{A B}$ and $\overline{A C}$ exists $\angle A$.

Angle between $\overline{D E}$ and $\overline{D F}$ exists $\angle D$.

Therefore, $\triangle A B C \cong \triangle D E F$ by SAS, if $\angle A \cong \angle D$$.
