Find the slope of a line PERPENDICULAR TO LM: L(3,-5), M(-4, -1)

Mathematics
1 answer:
Ede4ka [16]3 years ago
7 0

Answer:

\frac{7}4

Step-by-step explanation:

First, we need to find the slope, which is defined as the change in y over the change in x:

\frac{-5-(-1)}{3-(-4)} = \frac{-4}{7}

To find a slope that's perpendicular to that, we just take the negative reciprocal of that slope, which is \frac{7}4.

I hope this helped.

Frida started to solve the equation 3x = 36 by adding 3 to both sides. Explain why Friday’s method will not solve the equation.
vlada-n [284]

Explanation:

The equation is 3x=36

Frida started to solve the equation by adding 3 to both sides.

Thus, the equation becomes,

3x+3=39

This will not solve the equation.

To solve the equation 3x=36, we need to divide both sides of the equation by 3.

Thus, the equation becomes,

\frac{3x}{3} =\frac{36}{3}

Dividing we get,

x=12

Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.

Thus, to solve the equation 3x=36 Frida needs to divide both sides of the equation by 3.

Simplify the expression. Use standard polynomial format.<br> x(2x + 3) + (x - 3)(x - 4)
timofeeve [1]

Answer:

x(2x + 3) + (x - 3) (x - 4) = 3x²- 4x + 12

Step-by-step explanation:

<em>Expand:</em>

x(2x + 3): 2x² + 3x

2x² + 3x + (x - 3) (x - 4)

<em>Expand</em>:

(x - 3) (x - 4):  x²- 7x + 12

2x² + 3x + x²- 7x + 12

<em>Simplify:</em>

2x² + 3x + x² - 7x + 12:  3x² - 4x + 12

= 3x² - 4x +12
