Answer:

15m +2n

Step-by-step explanation:

8m+4n+7m-2n

Combine like terms

8m +7m +4n-2n

15m +2n

To simplify combine like terms:

8m + 7m = 15m

4n - 2n = 2n


Simplified: 15m + 2n

HELP ASAP
Naily [24]

Answer:

y+4 = -\frac{1}{3} (x-1)

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula m = \frac{y_2-y_1}{x_2-x_1} to find the slope. Substitute the x and y values of the given points into the formula and solve:

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

So, the slope is -\frac{1}{3}.

2) Use the point-slope formula y-y_1  = m (x-x_1) to write the equation of the line in point-slope form. Substitute values for m, x_1, and y_1 into the formula.

Since m represents the slope, substitute -\frac{1}{3}  in its place. Since x_1 and y_1 represent the x and y values of one point on the line, choose any one of the given points (it doesn't matter which one) and substitute the x and y values of it into the formula. (I chose (1,-4), as seen below). This gives the equation of the line in point-slope form.    

y-(-4) = -\frac{1}{3} (x-(1))\\y+4 = -\frac{1}{3} (x-1)

Determine if the two triangles shown are similar. If so, write the similarity statement.

I don’t think those are similar... not 100% sure tho. I think they need 2 matching angles to be similar.

Whats would the slope of (-3,10),(-5,-4) coordinates be?
valentina_108 [34]

Answer:

The slope is 7.

Step-by-step explanation:

Let the given points are (p, q)= (-3, 10) & (r, s) =(-5, -4).

Then the slope (m) = (s-q)/(r-p)

⇒ m = (-4 -10)/(-5-(-3))

⇒ m = (-14) / (-5 +3)

⇒ m = -14/- 2

⇒m = 7

Hence the slope is m =7 .
