Answer:

Step-by-step explanation:

11. 76x + 23x = 33

99x = 33

x = 33/99 which reduces to 3

12. 140r - 8r - 4r = 216

128r = 216

r = 216/128 which reduces to 27/16

13. 98c - 99c = 1

-1c = 1

c = -1/1

c = -1

14. 104mn + (-84mn) = 36

104mn - 84mn = 36

20mn = 36

mn = 36/20 which reduces to 9/5....I am not sure about this one...I was not sure if u were looking for m or n..so I didn't separate them. But if ur looking for m, it is m = 9/5n...and if ur looking for n, it is n = 9/5m

15. 118j - 234j = 234

- 116j = 234

j = -234/116 reduces to - 117/58

Graph △XYZ with vertices X(2, 3), Y(−3, 2), and Z(−4,−3) and its image after the translation (x, y)→(x+3, y−1)

viktelen [127]

Answer:

X'(5, 2)
Y'(0, 1)
Z'(-1, -4)

Step-by-step explanation:

The translation increases each x-coordinate by 3, moving the point 3 units to the right. It decreases each y-coordinate by 1, moving the point 1 unit down.

(x, y) ⇒ (x+3, y-1)

X(2, 3) ⇒ X'(5, 2)

Y(-3, 2) ⇒ Y'(0, 1)

Z(-4, -3) ⇒ Z'(-1, -4)

The red arrows show the translation of each point in the graph.

6x + 4y=10 12x + y= -29

Olin [163]

Answer: x=-3 y=7.

Step-by-step explanation:

$\displaystyle\\\left \{ {{6x+4y=10\ \ \ \ \ (1)} \atop {12x+y=-29\ \ \ \ (2)}} \right.\\ We\ multiply\ both\ sides\ of\ equation\ (1)\ by\ -2:\\\left \{ {{(-2)*6x+(-2)*4y=(-2)*10} \atop {12x+y=-29}} \right. \\\\\left \{ {{-12x-8y=-20} \atop {12x+y=-29}} \right. \\$ $We\ summarize\ equations\ (1)\ and\ (2):\\-7y=-49\\-7*y=-7*7\\Divide\ both\ sides\ of\ the\ equation\ by\ -7:\\y=7.\\We\ substitute\ the\ value\ of\ y\ into \ equation\ (1):\\6x+4*7=10\\6x+28=10\\6x+28-28=10-28\\6x=-18\\6*x=6*(-3)\\Divide\ both\ sides\ of\ the\ equation\ by\ 6:\\x=-3.$
