Answer:

A translation 2 units downward and reflection about the y-axis.

Step-by-step explanation:

The sequence of transformations that is applied to the quadrilateral ABCD to map onto the quadrilateral A"BC"D" is:

A translation 2 units downwards and then a reflection of the quadrilateral about y-axis.

( Since on translating two units downward all the coordinates of the vertex of the quadrilateral will be shifted two units down i.e. there will be a change in y-values and no change in x-values of the coordinates; and hence on reflecting about the y-axis, the image A"B"C"D" will be obtained )

bazaltina [42]

Answer:

the number of different three course meals that can be ordered equals 45

Step-by-step explanation:

In selecting Salads we have 5 choices.

In selecting pizza's we have 3 different choices

IN selecting dessert's we have 3 different choices

Thus the total number of choices to order the meal is

5 x 3 x 3=45.

Thus the number of different three course meals that can be ordered equals 45.

Which table describes the behavior of the graph of f(x) = 2x3 – 26x – 24?

In-s [12.5K]

Answer:

For x∈ {-∞,-3} y<0, below x-axis

x∈ {-3,-1} y>0, above x-axis

x∈ {-1,4} y<0, below x-axis

x∈ {4,∞} y>0, above x-axis

Step-by-step explanation:

f(x)= $2x^{3}-26x-24$

$2x^{3}-26x-24$ =0

$2x^{3}-26x-24=0\\2x^{3}-2x-24x-24=0\\2x(x^{2} -1)-24(x+1)=0\\2x(x+1)(x-1)-24(x+1)=0\\(x+1)(2x^{2} -2x-24)=0\\=> x+1=0 => x_{1}=-1\\$

$=> 2x^{2} -2x-24=0\\=>2(x^{2} -x-12)=0\\=> x^{2} -x-12=0\\=> x^{2} -4x+3x-12=0\\=> x(x-4)+3(x-4)=0\\=> (x-4)(x+3)=0\\$

$=> x-4=0\\=> x_{2}=4\\=> x+3=0\\=>x_{3}=-3\\$

For x∈ {-∞,-3} y<0, below x-axis

x∈ {-3,-1} y>0, above x-axis

x∈ {-1,4} y<0, below x-axis

x∈ {4,∞} y>0, above x-axis

Need help (pic included)

ValentinkaMS [17]

Answer:

(-4,-2)

x=-4

y=-2

Step-by-step explanation:

-3x-4y=20

3(x-10y=16)=3x-30y=48

The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.

-3x-4y=20

+ <u>3x-30y=48</u>

-34y=68

Divide -34 from both sides.

y=-2

To find x you need to plug in -2 for y into one of the equations.

x-10y=16

x-10(-2)=16

Remember a negative times a negative equals a positive.

x+20=16

Subtract 20 from both sides.

x=-4

Hope this helps!

If not, I am sorry.
