Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
Answer:
the answer is 4pi or 12.56637061
Step-by-step explanation:
the arc length equals 2pi x radius ( known angle (120) / 360 which equals 4pi or 12.56637061
Answer:
The graph with B(2,-3) i.e) y=
x goes through the point M(-10,15).
Step-by-step explanation:
Consider M(-10,15) and given that equation is y = kx.
Now, substitute M(-10,15) in the equation
⇒ 15 = k × -10
⇒ k =
= 
⇒ y =
x
Now, check with the given points B(2,-3) and B(
, -2)
1) B(2,-3)
y =
x
⇒(-3) =
× 2
⇒ -3 = -3 ⇒ LHS = RHS
⇒ B(2,-3) is the required point.
2) for b(
, -2)
LHS ≠ RHS.
So,The graph with B(2,-3) i.e) y=
x goes through the point M(-10,15).
Im pretty sure it is length times width :)
