The constant of proportionality is 1/5
Also flexing on us with that 5G
3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
Step-by-step explanation:
1. set it equal to 0 so t=5,9
2. this is wriiten in vertex notation so vertex is (7,4)
Step-by-step explanation:
3 3/5 - 1 1/10
3 6/10 - 1 1/10
2 2/10= 2 1/5 is the answer
Answer:
11
Step-by-step explanation:
4x - y = 13 >>>> y = 4x - 13
2x + y = 17 >>>> y = -2x + 17
so
4x - 13 = -2x + 17
4x + 2x = 17 + 13
6x = 30
x = 5
y = 4x - 13 = 4(5) - 13 = 7
then
3y - 2x = 3(7) - 2(5) = 21 - 10 = 11
