Answer:

-12

Step-by-step explanation:

The coordinates of B' are just 3 times the coordinates of B, so the multiplier in the dilation is 3.

C' is the point with coordinates 3 times the coordinates of C, making C'(3, -12).

The y-coordinate is -12.

-4r-11=4r+21 pls help <br>

Masja [62]

-4r-11=4r+21

Move 4r to the other side

Sign changes from +4r to -4r

-4r-4r-11=4r-4r+21

-4r-4r-11=21

-8r-11=21

Move -11 to the other side

Sign changes from -11 to +11

-8r-11+11=21+11

-8r=21+11

-8r=32

Divide both sides by -8

-8r/-8=32/-8

Answer:

1 ft : 2.5 yd or 1 ft : 2 1/2 yd

Step-by-step explanation:

He wants a real dimension of 10 yards to be represented by a scale dimension of 4 ft.

4 ft : 10 yd

Divide both sides by 4.

1 ft : 2.5 yd or 1 ft : 2 1/2 yd

Tell whether the ordered pair is a solution to the system of linear equations. 1 point

viktelen [127]

Answer:

(5,-6) is a solution

Step-by-step explanation:

Given

$6x + 3y = 12$

$4x + y = 14$

Required

Tell whether (5,-6) is a solution

In (5,-6): x = 5 and y = -6.

Substitute these values in the given equations

$6x + 3y = 12$ becomes

$6 * 5 + 3 * -6 = 12$

$30-18 = 12$

$12 = 12$

$4x + y = 14$ becomes

$4 * 5 - 6 = 14$

$20 - 6 = 14$

$14 = 14$

Because both solutions are true, then (5,-6) is a solution
