The answer is 150.
(5)^2(9-3)
25(6)
=150
Y varies inversely with x
means that y=k/x
with x=0.7 and y=80
we have 80=k/0.7
k=0.7x80=56
so the equation is
y=56/x
Answer:
I know this is late, but for<em> future people</em>:
I believe the answer is <u>2b+3c</u>.
Step-by-step explanation:
I'm pretty sure all you have to do is combine like terms.
I'm also taking the test at the moment.
Answer:
30
Step-by-step explanation:
Triangle containing 120° and y° is an isosceles triangle.
Therefore,
y° + 120° + y° = 180°
2y° = 180° - 120°
2y° = 60°
y° = 60°/2
y ° = 30°
y = 30
Answer:
No.
Step-by-step explanation:
Insert the x and y, (-5 is x and 6 is y) into the equation. It should look like 4(-5)+3(6)=9. 4(-5)=-20 and 3(6)=18. -20+18=2 not 9.
(hope this helps :P)
