Answer:

Given points (-8, -4) and (4,5)

Step-by-step explanation:

The equation of the line is given by

y - y1 = ((y2 - y1)/(x2 - x1)) (x-x1)

y + 4 =( 5+4)/ (4+8) ( x +8 )

y + 4 = 9/12 (x+ 8 )

y + 4 = 3/4 (x + 8)

4( y + 4 ) = 3(x + 8)

4y + 16 = 3x + 24

3x + 24 - 4y - 16 = 0

3x - 4y +8 = 0

Which is the required equation

-1≤ 3x-10≤ 2 please help me

kicyunya [14]

Answer:

3 ≤ x ≤ 4

Step-by-step explanation:

Step 1: Add 10 to all parts/sections.

$-1 + 10 \leq 3x - 10 + 10 \leq 2+10$
$9\leq 3x\leq 12$

Step 2: Divide all parts/sections by 3.

$\frac{9}{3} \leq \frac{3x}{3} \leq \frac{12}{3}$
$3 \leq x \leq 4$

Therefore, the answer is 3 ≤ x ≤ 4.

Prove cos a = 5/13 pls solve it and no link pls..........

Scorpion4ik [409]

Answer : The demonstration is below :)

Step-by-step explanation :

We use Pythagoras' theorem :

In the triangle ABC we have :

AB² = AC² - BC² = 15² - 9² = 144 = 12²

In the triangle ABD we have :

DB² = AD² - AB² = 13² - 12² = 5²

cos(a) = BD/AD = 5/13
