If LN = 6x - 5, LM = x + 7, and MN = 3x + 20, find MN
Ostrovityanka [42]

Answer:

68

Step-by-step explanation:

LM   +    MN     =   LN

x + 7  + 3x + 20 = 6x - 5

           4x + 27 = 6x - 5

          -4x         -4x      

                   27 = 2x - 5

                    +5        +5

                   32  = 2x

                   ÷2   ÷2    

                    16 = x

MN: 3x + 20

      3(16) + 20

        48   + 20

              68

Whoever answers correctly gets 100 points and brainlest
aleksklad [387]

Answer:

The only complete ordered pair in the given table is:

5 months → $60 saved

Therefore, to determine the <u>relationship between the variables</u>, divide the amount saved by the number of months:

\implies \sf \dfrac{Amount\:saved}{Number\:of\:months}=\dfrac{\$60}{5}=\$12

So we can assume that <u>$12 is saved each month</u>.

To complete the table:

  • <em>Multiply</em> the given number of months by $12 to determine the <u>amount saved</u>.
  • <em>Divide</em> the given amount saved by $12 to determine the <u>number of months</u>.

⇒ 3 × $12 = $36

⇒ $72 ÷ $12 = 6

⇒ 10 × $12 = $120

Completed table:

\large\begin{array}{| c | c |}\cline{1-2} \sf Times\:(month) & \sf Amount\:Saved\: (\$) \\\cline{1-2} 3 & 36 \\\cline{1-2} 5 & 60 \\\cline{1-2} 6 & 72 \\\cline{1-2} 10 & 120 \\\cline{1-2} \end{array}

Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (-5, -1); slop
RSB [31]

Answer:

The slope-intercept form of the equation of the line is y = -\frac{3}{5} \cdot x -4.

Step-by-step explanation:

We know that the slope-intercept form of the equation of the line is represented by:

y = m\cdot x + b

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

m - Slope, dimensionless.

b - y-Intercept, dimensionless.

From statement we find that m =-\frac{3}{5}. If x = -5 and y = -1, the value of the y-intercept is:

-1 =-\frac{3}{5}\cdot (-5)+b

-1 = 3 + b

b = -4

The slope-intercept form of the equation of the line is y = -\frac{3}{5} \cdot x -4.
