Step-by-step explanation:
L.H.S
tanA * cosecA
=sinA/cosA * 1/sinA
now cancel sinA and sinA
then,
1/cosA
= secA
= RHS
hence proved
Answer:
$6.32
Step-by-step explanation:
m + L = total $
6.35 + 7L = 50.59
7L = 44.24
L = 6.32
(-15x-3)+(7x-6)+(-2x+9)=-15x-3+7x-6+(-2x)+9=-15x-3+7x-6-2x+9=-10x
Answer:
Can I please have more details on what your question is?
Step-by-step explanation:
Answer:
-25 ≠ 21
Step-by-step explanation:
it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)
you would substitute -5 for x and 3 for y in the equation
5(-5) = 4(3) + 9
-25 = 12 + 9
-25 = 21
the question is asking you to see if the left side is equal to the right side of the equation
-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
