Find the value of x.
Answer:
x = 27
Step-by-step explanation:
because the angles are on a line that means they add up to 180
18 + x + 5x = 180
then combine like terms
18 + 6x = 180
then you subtract 18 from both sides
6x = 162
lastly divide both sides by 6
x = 27

Someone pls help I’ve been stuck on this all day and it’s due tomorrow!
Step-by-step explanation:
the first : e.g. a trapezoid
only 2 lines are parallel, but still it is a closed object with 4 vertexes and therefore 360° sum of internal angles. and 2 of the angles are smaller than 90°, and 2 are larger than 90°.
the second : a parallelogram, with all 4 sides having the same length. a square that is pushed e.g. on the top while the bottom stays.
the third : a rectangle. perpendicular means intersecting at 90°. but not a square. length and width must be different.

Find the domain of the inverse
The domain of the inverse of the function f(x) = 5e^x + 3 is found being all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
What is inverse of a function?Suppose that the given function is
[tex]f:X\rightarrow Y[/tex]
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
[tex]f^{-1}: Y \rightarrow X[/tex]
such that:
[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]
(and vice versa).
It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'
The domain of the inverse of a function (if it exists) is the range of the function it is inverse of. Similarly range of the inverse of that considered function is the domain of that considered function.
The function given is:
[tex]f(x) = 5e^x + 3[/tex]
The domain of the inverse of this function is this function's range.
Assuming only real values are allowed, for any real number x, we have:
[tex]e^x > 0[/tex]
And therefore, we get:
[tex]5e^x > 0 \: \forall x \in \mathbb R\\5e^x + 3 > 3 \: \forall x \in \mathbb R\\[/tex]
Also, since the function [tex]f(x) = 5e^x + 3[/tex] is strictly monotonically increasing and continuous, it touches all the values as its output from any real number > 3 till any finitely large number.
Thus, its range is (3, ∞) (it is an interval consisting of all the real numbers > 3)
This is the domain of its inverse function.
Thus, the domain of the inverse of the function f(x) = 5e^x + 3 is found being set of all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)

A group of friends wants to go to the amusement park. They have $318.50 to spend on parking and admission. Parking is $17, and tickets cost $33.50 per person, including tax. How many people can go to the amusement park?
Answer:
9 people
Step-by-step explanation:
The amount spent on tickets
318.5 - 17 = 301.5
If 301.5 was for tickets alone, the number of tickets can buy
301.5/33.5 = 9
Now

Answer:
x = -1/2.
Step-by-step explanation:
x^2 - 4 = (x - 2)(x + 2) so if we multiply each term by x^2 -4 we get:
2 - 1(x - 2) = 3(x + 2)
2 - x + 2 = 3x + 6
2 + 2 - 6 = 3x + x
4x = -2
x = -1/2.
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
1. Multiply both sides of the equation by the LCM (x - 2)(x + 2):
[tex]\frac{2}{x^{2} -4} (x-2)(x+2)[/tex]
factor x² - 4 by rewriting it as x² - 2²
x² - 2² = (x + 2)(x - 2)
now we have;
[tex]\frac{2}{(x+2)(x-2)} (x-2)(x+2)[/tex]
cancel the common factors (x - 2)(x + 2)
= 2
-------------------------------
[tex]\frac{-1}{x+2} (x-2)(x+2)[/tex]
cross cancel the common factor (x + 2)
[tex]\frac{-1}{x-2}=-(x-2)=-x+2[/tex]
-------------------------------
[tex]\frac{3}{x-2} (x-2)(x+2)[/tex]
cross cancel the common factor (x - 2)
3(x + 2)
distribute the 3
3x + 6
-------------------------------
combining all new values, we have;
2 + (-x) + 2 = 3x + 6
-x + 4 = 3x + 6
2. Isolate x:
-x + 4-4 = 3x + 6-4
-x = 3x + 2
-x-3x = 3x-3x + 2
-4x = 2
-4x/-4 = 2/-4
x = [tex]-\frac{1}{2}[/tex]
