9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
Answer:
6
Step-by-step explanation:
y + 1
= 7
y +
= 
y = 40/6 = 20/3 = 6
2 ones and 8 hundredths
00.00
the first zero is tens, ones, and after the decimal, to the right is the tenths, hundredths and so on
1/2 t-4(2+t)=20
1/2 t-8-4t=20
least common multiple=2
t-16-8t=40
-7t=40+16
-7t=56
t=56/-7=-8
Answer: t=-8
To check
-8/2 - 4(2-8)=-4-4(-6)=-4+24=20
