Sin45=AC/BC
1/(square root)2=(square root5)/x
X=(square root 2) x (square root 5)
X=(square root 10)
Answer:
y =
x
Step-by-step explanation:
given y varies directly as x, the the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition y = 10 when x = 6, hence
k =
=
= 
y =
x ← is the equation
Answer:
a = −bx+7x−4 over x
Step-by-step explanation:
solve for a:
7+ax−5x=3+2x−bx
add 5x to both sides:
ax−5x+7+5x=−bx+2x+3+5x
ax+7=−bx+7x+3
add -7 to both sides:
ax+7+−7=−bx+7x+3+−7
−bx+7x−4
lastly divide both sides by x.
