Answer:

$\bold{m=-2}$

Step-by-step explanation:

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(-2,\,5)\ \implies\ x_1=-2\,,\ y_1=5\\(3,\,-5)\ \implies\ x_2=3\,,\ y_2=-5\\\\m=\dfrac{-5-5}{3-(-2)}=\dfrac{-10}{3+2}=-\dfrac{10}5=-2$

Answer: 30

Step-by-step explanation: To solve this problem, we're going to have to use the Pythagorean theorem...

a² + b² = c²

24² + 18² = c²

576 + 324 = c²

c² = 900

$\sqrt{900}$

30 = c

I hope this helps!

QUICK HELP!!!!

sasho [114]

Answer:

$y = \frac{3}{4} x - \frac{3}{2}$

Step-by-step explanation:

$y = \frac{3}{4} x - 1→y - y1 = m( x - x1)$

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

$2(y - 6) = 2( \frac{3}{4} )(x - 6)$

$2y - 6= \frac{3}{2}( x - 6)$

$2y - 6 = \frac{3}{2} x - 9$

$- 6 \: from \: both \: sides$

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

$divede \: by \: 2 \: on \: both \: sides$

$y = \frac{3}{4} x - \frac{3}{2}$

Hope this helps!

A cab charges $1.75 for the flat fee and $0.25 for each mile. write and solve an inequality to determine how many miles eddie ca

ad-work [718]

The answer is a. $1.75 + $0.25x ≤ $15; x ≤ 53 miles

x - the number of miles
C - the cab charge

A cab charges $1.75 for the flat fee and $0.25 for each mile: C = 1.75 + 0.25x.
Eddie has $15 to spend. So, he cannot spend more than 15 on the cab and the maximum amount he can spend is 15. Therefore:
1.75 + 0.25x ≤ 15

Now, let's solve it:
0.25x ≤ 15 - 1.75
0.25x ≤ 13.25
x ≤ 13.25 / 0.25
x ≤ 53

If R is the midpoint of QS, RS=2X-4, ST=4X-1, and RT=8X-43, find QS

Cloud [144]

RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19

QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68
