Answer:
21:9
Step-by-step explanation:
when you divide 21 and 9 by 3, you get 7 and 3 respectively
wouldn't it be 6+8 I think that that's what it means by algebraic equation. Hope I could help.
(1/4)^-2 - (5^0 x 2) x 1^-1 =
(4/1)^2 - (1 x 2) x 1 = 16-2 = 14
If you raise something to the power of -2, swap numerator and denominator and remove the minus.
So (1/4)^-2 = 4^2 = 16
Also 1^-1 is just 1, not -1.
Where is crosses the x axis is the x intercept
it is also when y=0
so set y to zero
2x-3y=12
2x-3(0)=12
2x-0=12
2x=12
divide by 2
x=6
t
the y intercept=6 or (6,0)
