First you need to determine the defined range
(9x + 38) -
(x + 2) =
(81), x∈ (-2, + ∞)using the
(x) -
(y) =
(
), simplify the expression
(
) =
(81)
write the number in the second set of parenthesis in exponential form
(
) =
(9²)
using
(
) = x, simplify the expression
(
) = 2
the expression
(x) = b is equal to x =
= 7²
evaluate the power
= 49
multiply both sides of the equation by x + 2
9x + 38 = 49(x + 2)
distribute 49 through the parenthesis
9x + 38 = 49x + 98
move the variable to the left side and change its sign
9x - 49x + 38 = 98
move the constant to the right side and change its sign
9x - 49x = 98 - 39
collect the like terms
-40x = 98 - 38
subtract the numbers
-40x = 60
divide both sides of the equation by -40
x = -
, x ∈ (-2, + ∞)
finally,, check if the solution is in the defined range
x = -
this means that the correct answer to your question is x = -

3% Because if you would subtract the number of people that were invited and the number of people that only came, it would give you a total of 3% (hope that helped a little?)
Answer:
Step-by-step explanation:
y=mx+b
1/4 is your y intercept
-1/2 is your slope, so B
Answer:
16.6 degrees (to nearest tenth)
Step-by-step explanation:
Angle of inclination = the angle whose sine is 2/7.
Its the sine because 7 miles = hypotenuse and elevation ,2 miles , = opposite side).
This is 16.6 degrees (to nearest tenth)
Steps:
1. Turn 5 into 4 3/3
2. Do 4 3/3 - 1 2/3
3. 4-1=3
4. 3-2=1
5. Your answer is
3 1/3
