In figure 1, lines  ab,  cd,  ef,  and  gh  are  straight lines, and  cd  ⊥  ab.  indicate whether the following pairs of  angles are supplementary, complementary, or equal. (note: some  pairs of angles may satisfy more than one condition.)figure 1a.  ∠bogand ∠goab. ∠aoeand ∠eod  c. ∠godand ∠cohd. ∠bocand ∠coa  e. ∠hoband  ∠bog  f. ∠bohand ∠hod  g. ∠dohand  ∠cog  h. ∠boe  and ∠aoe  i. ∠bod  and ∠coa  j. ∠bof  and ∠foc

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

hi! i think the answer is 1/2 : )
