You may substitute -2x + 11 for the y in the first equation.
3x - (-2x + 11) = 9
3x + 2x - 11 = 9 Distribute the negative.
5x - 11 = 9 Combine like terms
5x = 20 Add 11 to both sides
x = 4 Divide both sides by 5.
Substitute 4 into one of the equations for x to solve for y.
3(4) - y = 9
12 - y = 9
-y = -3
y = 3
1300 u look at the number on the right and if it is greater than 5 u add 1
Answer:
m∠2 = 103°
Step-by-step explanation:
Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180.
Answer:
the X=1 and F=6 i think
Step-by-step explanation:
the table shows X increases by 1 and f is decreasing by 6 but im sure this is not the best explanation don't count on mine lol
