Answer:

a) x = 9 b) x = 10

Step-by-step explanation:

6² + (x - 1)² = (x + 1)²

36 + x² - 2x + 1 = x² + 2x + 1

36 = 4x

x = 9

x² + (x + 14)² = 26²

x² + x² + 28x + 196 = 676

2x² + 28x = 480

2x² + 28x - 480 = 0

x² + 14x - 240 = 0

(x + 24)(x - 10) = 0

x = -24 or 10

Answer:

a. 41.5

b, 26.5

Step-by-step explanation:

2x + 6 = 180

2x = 172

x = 86

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] $ y =

Advocard [28]

Answer:

The answer is " $\frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}$ ".

Step-by-step explanation:

Given:

$y = e^{{\color{\red}5}\sqrt{x}}$

let

$\to t= 5\sqrt{x}\\\\\frac{dt}{dx}= 5 \frac{1}{2\sqrt{x}}\\\\\frac{dt}{dx}= \frac{5}{2\sqrt{x}}\\\\$

and

$\to y=e^t\\\\\to \frac{dy}{dt}=e^t\\$

$\to \frac{dy}{dt}=e^{5\sqrt{x} }\\$

So,

$\to \frac{dy}{dx}= \frac{dy}{dt} \times \frac{dt}{dx}$

$=e^{5\sqrt{x} }\times \frac{5}{2\sqrt{x}}\\\\= \frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}$

$\to g(x) = 5\sqrt{x} \\\\\to f(x) = e^{(x)}\\\\$

Derivate:

$\to f''g' = \frac{e^{(5\sqrt{x})}5}{(2\sqrt{x})}$

There were 450 tickets purchased for a major league baseball game. the general admission tickets cost $6.50 and the upper box ti

lidiya [134]

Answer:

Step-by-step explanation:

So you first pretend they were all the general admission tickets which is

450x6.50$=2925$ So the number is 4237.50$-2925$=1312.50$ away from the actual price. The price difference between the two is 10.00$-6.50$= 3.50$

Then you put the total price difference 1312.50$ and divide by 3.50$ then you get the amount of upper box tickets. 1312.50$/3.50$=375( Amount of Upper box. So now you know how many upper box were bought. You take it away from 450 tickets sold. 450-375=75

375x10=3750$

75x6.5=487.5$

3750$+487.5$=4237.5$

Hope that helped you!

How do you equations like these? help a bro out pls

icang [17]

First solve for y

3x-y-2=1

subtract 3x from each side

-y-2=-3x+1

add 2 to both sides

-y=-3x+3

divide each side by -1

y=3x-3

To graph you could make a table:

x y

0 -3

graph that.... point and use rise over run for slope 3/1 and graph.
