answer:

slope = \frac{y_2 - y_1}{x_2 - x_1}

that's how you find the slope in any equation

The perimeter of a triangle is 199 inches. If one side of the triangle is six more than the shorter side, and the longer side is
Keith_Richards [23]
Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77

the 3 sides a + b + c = 199
b = a + 6
c = a + 19

substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58

then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77

*Brainliest*<br> I need help with 4 problems like this...KHAN ACADEMY.
Sedaia [141]

9514 1404 393

Answer:

  1. (x +1)² = 4
  2. (D)  x = -1 ±2

Step-by-step explanation:

Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.

  3 = x² +2x

Now, add the square of half the x-coefficient.

  3 +1 = x² +2x +1

  (x +1)² = 4 . . . . . . . . write as a square in the desired form

__

To solve, take the square root, and add the opposite of the left-side constant.

  x +1 = ±2

  x = -1 ±2 . . . . . . matches choice (D)

Through:(4,4),parallel to y=-6x +5
ad-work [718]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following equation of the line:

y = -6x + 5

Where:

m = -6

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have an equation of the form:

y = -6x + b

Substitute the given point(x, y) :( 4,4)to find "b":

4 = -6 (4) + b\\4 = -24 + b\\4 + 24 = b\\b = 28

Finally, the equation of the requested line is:

y = -6x + 28

Answer:

y = -6x + 28
