Point-slope form is y - y1 = m (x + x1)

First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1

13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2

Plug in the first point (as instructed) into the equation.

y - (-9) = -2 (x - 9)

Simplify the beginning.

y + [9] = [-2] (x + [-9])

(The brackets are the fill in the blanks)

Write the first trigonometric function in terms of the second for θ in the given quadrant.. sec θ, sin θ; θ in quadrant I

Grace [21]

We have sec = 1/cos

Then we also have cos^2 = 1 – sin^2

Also we have cos = sqrt (1 – sin^2)

Substitute the derived cosine function to sec then we have

Sec = 1/(sqrt(1-sin^2)

it's 3 miles around Westwood Park exercise Trail. after skating around the trail 5 and 1/2 times Mr Zorn lost a wheel. how many

svet-max [94.6K]

Mr. Zorn had skated total 17 miles.

Explanation

The length of the exercise trail around the Westwood park is 3 miles.

Mr. Zorn is skating around the trail 5 and 1/2 times.

So, the distance skated in 5 times $= (3* 5) miles = 15 miles$

and the distance skated in $\frac{1}{2}$ of the trail $= (3* \frac{1}{2})miles = 1.5 miles$

Thus, the total distance he had skated will be: $(15+1.5) miles = 16.5 miles \approx 17 miles$ (Rounded to the nearest mile)

Tickets for the community fair cost $12 for adults and $5 dollars for children. On the first day of the fair, 312 tickets were s

givi [52]

With this information we can set up 2 equations:

x + y = 312 (# of tickets sold for adults + # of tickets sold to adults = 312)

12x + 5y = 2204 ( # of tickets sold for adults times $12 + # of tickets sold to adults times $5 = $2204)

Where x is how many tickets were sold to adults and y how many tickets were sold to children

Now we can solve this system of equations by substitution:

isolate y in the first equation to find its value and plug it in the second equation

x + y = 312

isolate y by subtracting x from both sides:

x - x + y = 312

y = 312 - x

Apply y = 312 - x to the second equation

12x + 5y = 2204

12x + 5( 312 - x) = 2204

12x + 1560 - 5x = 2204

7x + 1560 = 2204

Subtract 1560 from both sides to isolate x

7x + 1560 - 1560 = 2204 - 1560

7x = 644

Divide both sides by 7

7/7x = 644/7

x = 92

Now plugin 92 for x in the first equation to find the value of y

x + y = 312

92 + y = 312

subtract 92 from both sides

92 - 92 + y = 312 - 92

y = 220

x = 92, y = 220

92 tickets were sold to adults and 220 tickets were sold to children

Hope it helps :)
