Answer:

2-4(x-1)

Step-by-step explanation:

Begin at 2 then subtract 4 for every (x-1) terms after.

Ex. the 10th term in the sequence is 2 - 4(10-1) = -34

Annette [7]
<span>3x + y =3 
Y = 2x - 7

substitute </span>Y = 2x - 7 into  3x + y =3 
3x + y =3 
3x +2x - 7 =3 
5x = 10
x = 2

Y = 2x - 7 = 2(2) - 7 = -3

Solve for x(need help)
bija089 [108]

Answer:

x = 18

Step-by-step explanation:

I the given triangle, it appears that M and N are the midpoints of the segments BG and BD respectively. If it so, then let us solve it.

By mid segment theorem:

2MN = GD

2(6x - 51) = 114

12x - 102 = 114

12x = 114 + 102

12x = 216

x = 216/12

x = 18

O A PQR is reflected over the x-axis. What are the<br> coordinates of O'?
topjm [15]

Answer:

(8,-2)

Step-by-step explanation:

When reflecting something across the X axis the y axis coordinate is the one that will change to put the position further up or down.  In this case we are moving it down to the same amount below the axis that it is now above it.  That means that since it is currently 2 above the X axis it would then be 2 below the X axis making it at -2 so the coordinates would be (8,-2)

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Sharonda is plotting quadrilateral PQRS on the graph below. She will plot the fourth and
lana [24]

Answer:

11 units

Step-by-step explanation:

Length of side PS can be calculated using the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Where,

P(-2, 5) = (x_1, y_1) (the coordinate of P is gotten from the graph)

S(9, 5) = (x_2, y_2) (given)

PS = \sqrt{(9 - (-2))^2 + (5 - 5)^2}

PS = \sqrt{(11)^2 + (0)^2}

PS = \sqrt{121} = 11 units
