Answer:
x=2
Step-by-step explanation:
Solve for x:
-20 = -10 x
-20 = -10 x is equivalent to -10 x = -20:
-10 x = -20
Divide both sides of -10 x = -20 by -10:
(-10 x)/(-10) = (-20)/(-10)
(-10)/(-10) = 1:
x = (-20)/(-10)
The gcd of -20 and -10 is -10, so (-20)/(-10) = (-10×2)/(-10×1) = (-10)/(-10)×2 = 2:
Answer: x = 2
The answer is 16.
—Explanation—
•] You can calculate how much you save by simply moving the period in 10.00 percent two spaces to the left, and then multiply the result by $16 as follows: $16 x .10 = $1.60 savings.
•] you get the final price by simply deducting .10 from 1 and multiplying it by $16 as follows: (1 - .10) x $16 = $14.40 final price.
To find the inverse of this function, we need to perform some steps.
f(x) = 2x + 9
Replace f(x) with y.
y = 2x + 9
Swap x and y.
x = 2y + 9
Solve for y.
Subtract both sides by 9.
x - 9 = 2y
Divide both sides by 2.
(x - 9)/2 = y
Replace y with f^-1(x)
<h3><u>f^-1(x) = (x - 9)/2</u></h3>
