X=30 is the correct answer

Since they are alternate interior angles, they will be congruent with each other.

4x= 5x-30

Subtract 5x on each side.

-1x= -30

Divide -1 into both sides.

x= 30

Now just plug in 30 too (4x) for the angle measure of both sides.

4*30 = 120

Each angle is equal to 120.

Hope this helps!

Write an equation of the line that passes through the point (3,-2) with slope -2.

Virty [35]

Answer:

y + 4 = -2(x - 3)

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h). Substitute -2 for k and 3 for h, as well as -2 for m:

y + 4 = -2(x - 3).

Let f and g be the functions defined by f(x) = 10^ (x+2 / 3) and g(x) = log (x3 / 100) for all positive real numbers,

Vaselesa [24]

Answer:

F(x) and g(x) are not inverse functions.

Step-by-step explanation:

In order to calculate the inverse function of a function, we have to isolate X and after that, we change the variables.

As our function f(x) is a exponentian function, we can apply logarithm with base 10 (log) in both sides in order to isolate X. Remember that log10=1.

$[tex]y=10^{(x+\frac{2}{3}) }\\\\log y=log 10^{(x+\frac{2}{3}) }\\log y = (x+\frac{2}{3}) . log10\\\frac{log Y}{log10} = (x+\frac{2}{3})\\\frac{log Y}{1} = (x+\frac{2}{3})\\log Y-\frac{2}{3}=x$ [/tex]
