6x = 9 – 3y
A) 1
B) None
C) Infinite
D) 2
B.)squaring both sides twice
C.)cubing both sides once
D.)cubing both sides twice
Answer:
cubing both sides once
Step-by-step explanation:
∛(5x-2)-∛4x=0
To solve this equation , we move second term to the other side
Add cube root (4x) on both sides
Now we remove cube root.
To remove cube root we take cube on both sides because cube and cube root will get cancelled.
So, cubing both sides once
Answer:
C
Step-by-step explanation:
rearrangeing:-
∛(5x - 2) = ∛((4x)
Cubing both sides:-
5x - 2 = 4x
Answer:
Let the full marks be y.
Then, the statement become : 30 marks is 40 % of y.
to solve for y;
40% of y can be written as
Then,
from the given condition we have;
or
Multiply both sides by in above equation;
Simplify:
Then, the full marks (y) = 75.
Therefore, 30 marks is 40% of 75.
Check:
30 =
30 =
30 =30 [True]
Answer:
Step-by-step explanation:
Let the equation of the line is y = mx + c
where m = slope = 3
and c = y-intercept
Now the equation of this line will become
y = 3x + c
Since this line passes through (2, )
so = 6 + c
c = - 6
=
So the line will be y = 3x +
