So let's say he was earring x before his raise. That means that:
x times 1.09 = 654 (1.09 represents 100% (this is the 1.0) of his original salary plus 9% (this is the .09) his raise.
So,
1.09x = 654; now divide both sides by 1.09 to isolate and solve for x, and you get x = $600.
The equation of a line in slope-intercept form is equal to
y=mx+b
where
m is the slope
b is the y-intercept
we have
m=-5/2
point (4,-3)
substitute in the expression above
-3=-(5/2)(4)+b
solve for b
-3=-10+b
b=10-3
b=7
therefore
the equation of the line is
<h2>y=-(5/2)x+7</h2>

Answer:
-5/3, or in decimal form, -1.666.
Step-by-step explanation:
a. -146 (3k+5) --- distribute the -146 to "3k" and "+5."
b. -438k - 730 = 0 --- get the variable k to one side of the equation.
c. -438k=730 --- divide by -438 on both sides.
d. the answer you get is 730/-438, which, in simpler terms, is -5/3, or -1.666.
