Answer:

Step-by-step explanation:

The sum of measures of angles in triangle is 180°, so the measure of the ohter acute angle:

180° - 90° - 47° = 43°

Write an equation in slope intercept form for <br> the given slope.<br> (5,9).(6,8)

vovangra [49]

<u>Answer: </u>

The equation in slope intercept form for (5,9) and (6,8) is y = 3x-10

<u>Solution: </u>

Given that (5,9) and (6,8)

Here, $x_{1}=5 ; y_{1}=5 ; x_{2}=6 ; y_{2}=8$

We know the slope of an equation is given by y = mx+c

To find the value of m, we use the below given formula

$\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting the values we get,

$\mathrm{m}=\frac{8-5}{6-5}$

$m = \frac{3}{1}$

m = 3

Putting the value of m in the slope intercept form we get,

y = 3x+c

To find the value of c, we substitute the value of x and y from any two given point. Let’s take x = 5 and y = 5

5 = 3(5) + c

5 = 15 +c

5-15 = c

c = -10

Therefore the slope intercept equation becomes y = 3x -10

Please help<br> if x = 3 and y=-4 find x2 + y2 and x2 -y2

lions [1.4K]

1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2

Hope this helped, have an awesome day!

18 out of the 25 students are going on the field trip. What percent of the students are going on the field trip?

il63 [147K]

Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25.
18/25 = 0.72

Convert decimal into fraction.
0.72 = 72%

Thus, 18 out of 25 students = 72% of students who are going on the field trip.

You're welcome.

(High points) please solve with explanation. Legit answers only thank you!

Step-by-step explanation:

The x-intercept is at (-3, 0). To find the slope of the perpendicular line, let's rewrite the equation to its slope-intercept form, which is

y = (2/3)x + 2

This means that the perpendicular line has a slope m = -3/2. So the slope-intercept form of this new line is

y = -(3/2)x + k. Since this line passes through (-3, 0), we cal solve for k:

0 = -(3/2)(-3) + k or k = -9/2

So our equation becomes (slope-intercept form)

$y = - \frac{3}{2}x - \frac{9}{2}$

or in its standard form,

$3x + 2y + 9 = 0$
