I’m not positive but I think all you have to do is minus 62 from 180 which would be 119

What are the solutions of x ^ 2 + 6x - 6 = 10 ? x = - 11 x = 1 x = - 11 x = - 1 x = - 8x = - 2 x = - 8x = 2
zmey [24]

Answer:

x=-8 ,2

Step-by-step explanation:

x ^ 2 + 6x - 6 = 10

Add 6 to each side

x ^ 2 + 6x - 6+6 = 10+6

x ^ 2 + 6x  = 16

Complete the square  take the coefficient of the x terms, divide by 2 and square it.  Then add it to each side

6/2 =3  , 3^2 =9  

x ^ 2 + 6x +9 = 16+9

(x+3)^2 = 25

Take the square root of each side

sqrt((x+3)^2) = ±sqrt(25)

x+3= ±5

Make 2 equations

x+3 = 5    x+3 = -5

Subtract 3 from each side

x+3-3 =5-3             x+3-3 = -5-3

x =2                           x=-8

HURRY PLEASE!!!!! Triangle RST is translated 2 units left and then reflected over the y-axis.
AVprozaik [17]

Answer:

The correct options are 1 and 2.

Step-by-step explanation:

The vertices of triangle are S(-4,4), T(-1,4), R(-1,1).

If triangle translated 2 units left,

(x,y)\rightarrow (x-2,y)

and then reflected over the y-axis,

(x-2,y)\rightarrow (-x+2,y)

The relation between image and preimage is

(x,y)\rightarrow (-x+2,y)                          ..... (1)

The vertices of image are

S(-4,4)\rightarrow S'(6,4)

T(-1,4)\rightarrow T'(3,4)

R(-1,1)\rightarrow R'(3,1)

Therefore the vertices of image are S'(6,4),T'(3,4), R'(3,1).

1. A reflection over the y-axis and then a translation 2 units right is defined as

(x,y)\rightarrow (-x+2,y)

It is equivalent to relation 1, therefore option 1 is correct.

2. A 180 rotation about the origin, then a translation 2 units right, and then a reflection over the x-axis is defined as

(x,y)\rightarrow (-x+2,y)

It is equivalent to relation 1, therefore option 2 is correct.

3. A reflection over the y-axis and then a translation 2 units left is defined as

(x,y)\rightarrow (-x-2,y)

It is not equivalent to relation 1, therefore option 3 is incorrect.

4. A 180 rotation about the origin, then a translation 2 units left, and then a reflection over the x-axis is defined as

(x,y)\rightarrow (-x-2,y)

It is not equivalent to relation 1, therefore option 4 is incorrect.

5. A reflection over the x-axis and then a translation 2 units right is defined as

(x,y)\rightarrow (x+2,-y)

It is not equivalent to relation 1, therefore option 5 is incorrect.

6. A reflection over the x-axis and then a translation 2 units left is defined as

(x,y)\rightarrow (x+2,-y)

It is not equivalent to relation 1, therefore option 6 is incorrect.

Therefore the correct options are 1 and 2.

zysi [14]

Answer:

41

Step-by-step explanation:

The number 1 is in the ones place. 1x4=4, so 4 is in the tens place. If you reverse 41, you get 14. 41+14=55.
