I think its 9 because 5x+15=50 you subtract 15 from both sides and then divide.

Yoko drove 522 miles in 9 hours. At the same rate, how many miles would she drive in 13 hours?
Stella [2.4K]

Yoko would drive 754 miles in 13 hours.

First you would have to find how many miles Yoko drives per hour so you divide 522 miles/9 hours to get 58 miles per 1 hour. Then you multiply 58 * 13 to get 754 miles.

Solve the problem. A $8920 note is signed, for 160 days, at a discount rate of 6.5 % Find the proceeds.
GuDViN [60]
<h2>Hello!</h2>

The answer is $101688

<h2>Why?</h2>

Since there is not enough information about the rate, let's assume that it's a daily rate.

<h2>Calculations</h2>

Let's say:

P : Proceeds

o : original amount

d : number of days

r  : percentual rate

So,

P = o + o*(r*d)\\

Let's make the percentual rate (6,5%) a real number by dividing into 100,

\frac{6,5}{100}=0,065


By substituting, we have

P = $8920 + $8920*(0,065*160)= 8920 + 8920*10,4\\P= $8920 + $92768 = $101688

P = $101688

Have a nice day!

Print out the graph paper from the "Let's Review" section. Sketch the graph of y = 2tanx for -pi/2 ≤ x ≤ pi/2
snow_lady [41]

Answer:

<h2>The graph is attached below.</h2><h2>Same asymptote as similarity and the slopes are different.</h2>

Step-by-step explanation:

We need to find the graph of y = 2 \times tanx.......... \frac{-\pi }{2} \leq  x \leq \frac{\pi }{2}

When x = 0; y = 0\\x = \frac{\pi }{4} ; y = 2\\x = - \frac{\pi }{4} ; y = -2

and \lim_{x \to \frac{\pi }{2} } y =  \infty\\ \lim_{x \to - \frac{\pi }{2} } y = - \infty

The asymptotes are x = \frac{\pi }{2} \\ x = - \frac{\pi }{2}

If we compare the graphs of y = 2 \times tanx.....(1)\\y = tanx......(2)

then the similarities are, they have same asymptote.

Difference between them is the rate of change that is the slope of the equations.
