<span>Simplifying 4(-8x + 5) + -1(-33x + -26) = 0 Reorder the terms: 4(5 + -8x) + -1(-33x + -26) = 0 (5 * 4 + -8x * 4) + -1(-33x + -26) = 0 (20 + -32x) + -1(-33x + -26) = 0 Reorder the terms: 20 + -32x + -1(-26 + -33x) = 0 20 + -32x + (-26 * -1 + -33x * -1) = 0 20 + -32x + (26 + 33x) = 0 Reorder the terms: 20 + 26 + -32x + 33x = 0 Combine like terms: 20 + 26 = 46 46 + -32x + 33x = 0 Combine like terms: -32x + 33x = 1x 46 + 1x = 0 Solving 46 + 1x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-46' to each side of the equation. 46 + -46 + 1x = 0 + -46 Combine like terms: 46 + -46 = 0 0 + 1x = 0 + -46 1x = 0 + -46 Combine like terms: 0 + -46 = -46 1x = -46 Divide each side by '1'. x = -46 Simplifying x = -46</span>

Find the slope of the line that goes through the points (-1,-4) and (9, 20). You must show all of your work in the space provide
Setler [38]

Answer:

12/5

Explanation:

To find the slope of the line, we'll need to use the below formula;

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

where x1 = -1, y1 = -4, x2 = 9, y2 = 20, so let's go ahead and substitute these values into our formula and solve for m;

m=\frac{20-(-4)}{9-(-1)}=\frac{20+4}{9+1}=\frac{24}{10}=\frac{12}{5}

Answer:

B:  (x - 4)² = 44

Step-by-step explanation:

Start with x^2 - 8x - 10  =  18.

Simplify the constants by adding 10 to both sides:  x^2 - 8x - 10 + 10 = 18 + 10.

Then x^2 - 8x = 28.

Now identify the coefficient of x.  It is -8.  

Take half of this, obtaining -4.

Square this result, obtaining 16.

Add 16, and then subtract 16, to x^2 - 8x:

x^2 - 8x + 16 - 16 = 28.

Add 16 to both sides:

x^2 - 8x + 16 = 28 + 16 = 44

Rewrite x^2 - 8x + 16 as (x - 4)², so that we have:

(x - 4)² = 44.  This is in the form (x - p)² = 44, and matches Answer B.

Note:  Please use " ^ " to indicate exponentiation:  (x - 4)^2 = 44

HELP PLEASEEEE!! First correct answer gets brainliest ! ​
mylen [45]

Answer:

2

Step-by-step explanation:

The slope of a line is rise/run.

First, you must choose any two points on the line.

Rise is how many spaces a line moves upward or downward from one point to another.

The run is how many spaces a line moves left or right from one point to another.

It is given that from point M to point N, the line moves up 4 spaces and runs to the right 2 spaces.

  • 4 = rise
  • 2 = run
  • Slope = 4/2, which can be simplified to 2, because 4 divided by 2 is 2.
