Rhoda is asked to graph this system of equations: 5x - 6y = 4 3y + 2x = 7 How many times will the lines intersect? O A. The line
Daniel [21]

Answer:

  • C. The lines will intersect once, because this system has one solution

Step-by-step explanation:

<u>System of equations: </u>

  • 5x - 6y = 4
  • 3y + 2x = 7

The system of linear equations has one solution if the lines intersect, no solution if the lines are parallel, infinitely many solutions if lines are same

Let's put the lines into slope-intercept form to compare

<u>Line1 </u>

  • 5x - 6y = 4
  • 6y = 5x - 4
  • y = 5/6x - 4/6

<u>Line </u>2

  • 3y + 2x = 7
  • 3y = -2x + 7
  • y = -2/3x + 7/3

As we see lines have different slopes so they are different and they intersect once

This system has one solution

Match the equation with its corresponding solution for x.
Fudgin [204]

To solve for x, you need to isolate/get the variable "x" by itself in the equation:

3x - 3(x + 1) = 3     Distribute/multiply -3 into (x + 1)

3x + (-3)x + (-3)1 = 3

3x - 3x + 1 = 3

1 = 3

Your answer is no solution because the variable "x" is canceled out and 1 ≠ 3

Expand the binomial (2x+5)^5
Whitepunk [10]
That would simplify to 32x^5+400x^4+200x^3+5000x^2+6250x+3125
You would do that because you have to write it repeatedly as (2x+5)(2x+5) and so on.
