Answer:
(4,0) and ( 0,-4)
Step-by-step explanation:
The solutions are the the graphs intersect
There are two points
(4,0) and ( 0,-4)
Since the straight line has a negative slope and passes therough the first, second and fourth quadrants, the value of y when x = -3 will be a positive number greater than 3.
Therefore, the correct answer is option A (y = 4)
Answer:
the answer is 7
Step-by-step explanation:
divide the numerator (21) by the denominator (3) and you will get 7 as the answer hope this helped
3y = -1/2x + 2 . . . . . . . . (1)
y = -x + 9 . . . . . . . . (2)
substituting (2) into (1), we have
3(-x + 9) = -1/2x + 2
-3x + 27 = -1/2x + 2
-1/2x + 3x = 27 - 2
5/2x = 25
x = (2 x 25)/5
x = 10
From (2)
y = -10 + 9
y = -1
solution (10, -1)
