Answer:

Concept: Vectors

  1. I think the confusion here might be the usage of i and j
  2. Just to let you know, i=x and j=y
  3. So let's use that fact to conceptualize this
  4. 6x^3+4y^2-6x
  5. We can simplify by applying a common factor
  6. 2(x^3+2y^2-3x)
  7. Thats the most we can simplify this

the sum of two numbers is 7 five times the larger number plus four times the the smaller number is 47.
Natali5045456 [20]
Let x and y represent the larger and smaller numbers, respectively. The problem conditions give rise to two equations:
  x + y = 7
  5x +4y = 47

You can use the first equation to write an expression for y, then substitute that into the second equation.
  y = 7 - x
  5x +4(7 -x) = 47 . . . . substitute for y
  x + 28 = 47 . . . . . . .. simplify
  x = 19 . . . . . . . . . . . . subtract 28

Using our expression for y, we have
  y = 7 -19 = -12

The larger number is 19.
The smaller number is -12.

Find the slope of the line containing the pair of points.<br> (-3,1) and (1, - 11)
ololo11 [35]

Answer:

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

x2 = -3

x1 = 1

y2 = 1

y1 = - 11

slope = (1 - - 11) / (-3 - 1)

slope = 12 / - 4

slope = - 3
