Answer:

x = 10

z = 116°

Step-by-step explanation:

By the definition of supplementary angles, we have:

Step 1: Find x

7x + 46 + 5x + 14 = 180

12x + 60 = 180

12x = 120

x = 10

Step 2: Find the supplementary angle to z

5(10) + 14

50 + 14

Step 3: Find z

180 - 64 = 116

PLEASE HELP SOLVE FOR Y

alexgriva [62]

Hello!

$\large\boxed{y = 5(\frac{1}{2})^{x} }$

Recall that the equation of an exponential graph is:

$y = a(b)^{x}$

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

$5 = a(b)^{0}\\\\5 = a(1)\\\\a = 5$

Solve for b by plugging in another point on the graph:

$10 = 5(b)^{-1}\\\\2 = b^{-1}\\\\b = 1/2$

Write the final equation:

$y = 5(\frac{1}{2})^{x}$

Answer:

$x^{36}-x^{16}$ is already at its simplest form

Step-by-step explanation:

You cannot factor or GCF anything out of it, and you cannot just subtract exponents. Therefore, it is simplified already.
