Answer:

1. Put the equation into the form ax 2 + bx = – c.

2. Make sure that a = 1 (if a ≠ 1, multiply through the equation by. before proceeding).

3. Using the value of b from this new equation, add. ...

4. Find the square root of both sides of the equation.

5. Solve the resulting equation. Hope this helps in some way.

Solve the equation. Round to the nearest thousandth. -12e-x + 8 = 7

Marysya12 [62]

Answer:

-12e-x + 8 = 7

-12e-x = 7-8

-12e-x = -1

12e-x = 1

e-x = 1/12

ln(e-x) = ln(1/12)

x = -ln(1/12)

x = -2.485

What is the answer to 10k-9=9k + 10?

oee [108]

K=19 which would leave the equation 181=181. The first step to solving this is subtracting 9k from each side.
after you do that it should be k-9=10
now you add 9 to both sides leave k=19. plug k into the equation and get 181=181

(3, 1.5) (4,0) the slope

Naya [18.7K]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -3/2</h3>

════════════════════

<h3>Known</h3>

x1 = 2

y1 = 1.5

x2 = 4

y2 = 0

════════════════════

<h3>Question</h3>

the slope = gradient (m)

════════════════════

$m = \frac{y2 - y1}{x2 - x1} = \frac{(0 - 1.5)}{(4 - 2)} = \frac{( - 1.5)}{2} = - \frac{3}{2}$

════════════════════

•Formula of the slope (m)

$\boxed {\ m = \frac{y2 - y1}{x2 - x1}}$
