Answer:
a = -4/9
Step-by-step explanation:
(9a + 4) = 0
Subtract 4 from each side
9a + 4-4 = 0-4
9a = -4
Divide each side by 9
9a/9 = -4/9
a = -4/9
Answer:
(5,6)

please mark me the brainiest i hope this has helped
Answer:
40/41
Step-by-step explanation:
From the given diagram;
BA is the hypotenuse = 41
AC is the opposite = 9
CB is the adjacent = 40
Cos<B = adjaccent/hyp
Cos<B = CB/BA
Cos<B = 40/41
Hence the required ratio is 40/41
Answer:
X = 18
Y = 18
Step-by-step explanation:
first make two equation like
x + y = 36
1180x + 125y = 23490
from equation one we have
y = 36- x
put in second equation
1180x + 125 (36-x) = 23490
1180x + 4500-125x = 23490
1055x = 23490-4500
x = 18990/1055
x = 18
put this x value in equation 1 to find y value
18+ y = 36
y = 36-18
y = 18
