Help me out please simple

const2013 [10]

A straight line is 180 degrees in measure

The straight line is made up of three angles

--> angle 1

--> angle 2

--> angle with a little square on it

(angle with a little square means it is 90 degrees in measure)

Let's set up an equation

$angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3$

Thus angle 1 is 3 degrees or the second choice

Hope that helps!

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:

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