Answer:

When the shape reflects about the x-axis, the x-coordinate is unchanged but the y-coordinate becomes negative. When the shape reflects about the y-axis, the y-coordinate is unchanged but the x-coordinate becomes negative.

The x values stay the same but the y values change to their opposites.
For example: (2,4) reflected across the x-axis would be (2, -4)
and (6, -3) reflected across the x-axis would be (6, 3)
I hope you understand my explanation.

4. Harry is going to send some flowers to his wife. Summerfield Florist charges $1 per rose, plus

k0ka [10]

The number of roses purchased will be; 12 roses

The total cost of the bouquet is; $51

Let number of roses be x

For Summerfield florists;

At $1 per rose and $39 for the vase, cost is;

C = x + 39

For grayson's flowers;

At $3 per rose and $15 for the vase,total cost is;

C = 3x + 15

We are told when he orders a certain number of roses, the cost will be the same with each flower shop.

Thus;

x + 39 = 3x + 15

3x - x = 39 - 15

2x = 24

x = 24/2

x = 12

Total cost is;

C = 12 + 39

C = $51

Answer:

A. 18

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

A = 1/2(b1 +b2)h

Here, the parallel bases have lengths 3 and 9. The height is 3, so the area is ...

A = 1/2(3 +9)(3) = 18

The area of the trapezoid is 18 square units.

Which two points are on the graph of y=x - 4?

julia-pushkina [17]

Replace x with the value in the answers and solve for Y to see which ones match.

y = 1-4 = -3

y = -1-4 = -5

(1,-3), (-1,-5) is the answer.

A set of weights includes a 10 lb barbell and 8 pairs of weight plates. Each pairof plates weighs 20lbs. If x pairs of plates ar

Leni [432]

It is given that the weight of the barbel is given by:

$f(x)=20x+10$

It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:

$\begin{gathered} x=0,f(x)=10 \\ x=1,f(x)=30 \\ x=2,f(x)=50 \\ x=3,f(x)=70 \\ x=4,f(x)=90 \\ x=5,f(x)=110 \\ x=6,f(x)=130 \\ x=7,f(x)=150 \\ x=8,f(x)=170 \end{gathered}$

So the range is:

$\mleft\lbrace10,30,50,70,90,110,130,150,170\mright\rbrace$

Option B is correct.
