To find the sum and difference of the two rocks, you would do:

\frac{3}{8} + \frac{2}{8} =  \frac{3+2}{8} =\boxed{\bf{\frac{5}{8}}}\\\\\\ \frac{3}{8} - \frac{2}{8} =  \frac{3-2}{8} =\boxed{\bf{\frac{1}{8}}}

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

Consider the figure shown below. Find the value of BL
Gnesinka [82]

Answer:

BL = 2

Step-by-step explanation:

Given:

AL = 3

AC = 10

BC = 9

AL = AM = 3 (tangents drawn form am external point)

CM = AC - AM

CM = 10 - 3

CM = 7

CM = CN = 7 (tangents drawn form am external point)

BN = BC - CN

BN = 9 - 7

BN = 2

BN = BL = 2 (tangents drawn form am external point).

BL = 2
