Answer:

its the second one

Step-by-step explanation:

its the second one because the statement RWS=TUV shows which angles are congruent in order meaning that ang r and t are congruent angle w and u are congruent and angle v and s are congruent. so t and s are not congruent

B.T S is the answer to the question you asked

Answer:

2 ordered pairs are solutions:

(1, -11) and (3, -9)

Step-by-step explanation:

The pairs (1, -11) and (3,-9) are the solution to the system of equations.

Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.

For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.

If any coordinate or point is satisfy an equation then it will be solution of that equation.

Taking y = x - 12

If we keep all points one by one then we get to know that,

Point (1,11) and (3,-9) are satisfying;

(1, -11) ⇒ -11 = 1 - 12 = -11

(3,-9) ⇒ -9 = 3 - 12 = -9

Hence "The pairs (1, -11) and (3,-9) are the solution to the system of equations".

Answer:

It will take 10.63 years.

Step-by-step explanation:

Giving the following information:

Present value (PV)= $4,000

Future Value (FV)= $10,000

Interest rate (i)= 9% annual compounded

To calculate the time required to reach $10,000, we need to use the following formula:

n= ln(FV/PV) / ln(1+i)  

n= number of years

n= ln(10,000 / 4,000) / ln(1.09)

n= 10.63

It will take 10.63 years.

Answer:

y = 16

Step-by-step explanation:

you can set 6x - 13 and 8x - 61 equal to each other because they are Alternate-Exterior angles and are congruent; this will give you the value of 'x'

6x - 13 = 8x - 61

-13 = 2x - 61

2x = 48

x = 24

3y + 1 + 8x - 61 = 180   (they form a straight line)

substitute 24 for 'x'

3y + 1 + 8(24) - 61 = 180

3y + 132 = 180

3y = 48

y = 16

Answer:

ABCD is a trapezoid which has two equal sides => this is an isosceles trapezoid

=> BAD = CDA

=> BAD = 37⁰ + 34⁰ = 71⁰

because AD//BC

=> BAD + ABC = 180⁰

=> ABC = 180⁰ - BAD = 180⁰ - 71⁰ = 109⁰

6x+7y=14

Step-by-step explanation:

this may be wrong

but i tried

Step-by-step explanation:

y - x = 3x +2

y=3x+x+2

y=4x+2.......(1)

2x + 2y = 14 - y

2x+2y+y=14

2x+3y=14.........(1)

substituting value of y in equation 1

2x+3(4x+2)=14

2x+12x+6=14.

14x=14-6

14x=8

x=8/14=4/7

substituting value of x in equation 1

y=4×4/7+2=30/7

x=4/7

y=30/7

Answer:

The Direction of the rotation is counterclockwise around the origin.

What was Given was that Point G is rotated 90°. The coordinate of the pre-image point G was (7, –5), and its image G’ is at the coordinate (5, 7).

What you need to find was : What is the direction of the rotation.

So coming to conclusions is we have given that Point G is rotated 90°.

The Pre-image of G = ( 7, -5).

Translated image G' = ( 5 ,7).

By the Rotation rule of 90° is : (-y, x) 90 degree rotation counterclockwise around the origin.

(y, -x) 90 degree rotation clockwise about the origin.

We can from G (7,-5) and G'( 5 ,7) it is rotation counterclockwise around the origin.

Therefore, Direction of rotation is counterclockwise around the origin.
