3x + y = -5

-3x + 3x + y = -3x - 5

y = -3x - 5

The points (-6, r)<br> and<br> (6,3) lie on a line with slope 3/4. Find the missing coordinate r.

NeTakaya

Answer:

r = -6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Slope 3/4

This means that $m = \frac{3}{4}$ , and thus:

$y = \frac{3}{4}x + b$

(6,3)

This means that when $x = 6, y = 3$ . We use this to find b. So

$y = \frac{3}{4}x + b$

$3 = \frac{3}{4}(6) + b$

$b = 3 - \frac{18}{4} = \frac{12}{4} - \frac{18}{4} = -\frac{6}{4}$

So

$y = \frac{3}{4}x - \frac{6}{4} = \frac{3x - 6}{4}$

(-6, r)

r is y when $x = -6$ . So

$y = \frac{3(-6) - 6}{4} = -6$

So r = -6.

Find x in each triangle.

arsen [322]

#1. x= 5

(because it’s a 3,4,5 triangle and follows pythagorean theorem)

#2. x= 9

(225-144= 81, square root of 81 is 9)

#3. x= 8

(100-36= 64, square root of 64 is 8)

hope this helps!

Which sequence is arithmetic?

Evgen [1.6K]

9, 18, 27, 36…
This is because the growth is linear. When you add 9, you get the next number in the sequence.
