Step-by-step explanation:

m \angle \: C =  \frac{1}{2} (m \: arc \: AB)\\(By\:inscribed \:\angle\:theorem) \\  \\  \therefore \: (x + 5) \degree =\frac{1}{2} (4x)\degree  \\  \\ \therefore \: x + 5=\frac{1}{2} \times  4x \\  \\ \therefore \: x + 5=2x \\  \\ \therefore \: x  - 2x =  - 5 \\  \\ \therefore \:  - x =  - 5 \\  \\ \:  \:  \:  \:  \:   \huge \purple{ \boxed{\therefore \:  x =   5}}

Leona [35]

Answer: D.

Step-by-step explanation: First you find the common factor, which is 5x³y. Then you write in parenthesis what's left over from each term. So  the answer should look like: 5x³y(-3x⁵-4z+9).

What set of transformations could be applied to rectangle ABCD to create A″B″C″D″? 'Rectangle formed by ordered pairs A at negat
CaHeK987 [17]

Answer:

Reflection over the y-axis and rotation of 180°

Step-by-step explanation:

We have,

Rectangle ABCD with co-ordinates A(-4,2), B(-4,1), C(-1,1) and D(-1,2).

It is transformed to a new rectangle A'B'C'D' with co-ordinates A'(-4,-2), B'(-4,-1), C'(-1,-1) and D'(-1,-2).

The graph of both the triangles is shown below.

we see that,

The rectangle ABCD is reflected about y-axis and then rotated 180° to obtain A'B'C'D'.

                     Reflected about y-axis                     Rotation of 180°

A= (-4,2)                     (4,2)                                              A'= (-4,-2)

B= (-4,1)                      (4,1)                                                B'= (-4,-1)

C= (-1,1)                       (1,1)                                                 C'= (-1,-1)

D= (-1,2)                      (1,2)                                                 D'= (-1,-2)

Hence, the second rectangle is formed by: Reflection over the y-axis and rotation of 180°.

romanna [79]

Answer:

-6.20x-6.20y=-948.6

add this to equation 2

6.20x-6.20x +9.30y-6.20y=1125.30-948.60

3.10y= 176.70

/3.10

y=176.70/3.10

y = 57 number of adult tickets

153-57=96 child tickets

Step-by-step explanation:

child admission is $6.20 : x numbers

adult admission is $9.30 : y numbers

153 tickets were sold  

sales of $1125.30 .  

x+y = 153.........................1

6.20x+9.30y= 1125.30..............2
