Korvikt [17]3 years ago
8 0

Answer:

y=10x+3

Step-by-step explanation:

you can't solve this because there is only one equation, so i guess you want it in slop-intercept form

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle J
Lynna [10]

Answer:

option C. KL=2*JL

option D. JK=\frac{\sqrt{3}}{2}*KL

option F. JK=\sqrt{3}*JL

Step-by-step explanation:

step 1

we know that

In the right triangle JKL

sin(30\°)=\frac{JL}{KL}

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{JL}{KL}

KL=2*JL

step 2

cos(30\°)=\frac{JK}{KL}

cos(30\°)=\frac{\sqrt{3}}{2}

so

\frac{\sqrt{3}}{2}=\frac{JK}{KL}

JK=\frac{\sqrt{3}}{2}*KL

step 3

tan(30\°)=\frac{JL}{JK}

tan(30\°)=\frac{1}{\sqrt{3}}

\frac{1}{\sqrt{3}}=\frac{JL}{JK}

JK=\sqrt{3}*JL

What is the equation of the line that passes through the point (5, -2)<br> and has a slope of 6/5
liubo4ka [24]

Answer:

        y + 2 = ⁶/₅(x - 5)     {the point-slope form of the equation}

        y = ⁶/₅x - 8            {the slope-intercept form of the equation}  

         6x - 5y = 40           {the standard form of the equation}

Step-by-step explanation:

The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.

m = ⁶/₅

(5, -2)    ⇒   x₀ = 5,  y₀ = -2

So, the point-slope form of the equation:

y + 2 = ⁶/₅(x - 5)

Therefore:

y + 2 =  ⁶/₅x - 6          {subtract 2 from both sides}

y = ⁶/₅x - 8              ←  the slope-intercept form of the equation

-⁶/₅x + y = - 8                    {multiply both sides by (-5)}

6x - 5y = 40               ←  the standard form of the equation

Write the equation of the line parallel to the given line and passing through the given point. y= 1/2 x+2 through (0,4)
marshall27 [118]

Parallel lines have the same slope, so the slope of the new line is 1/2.

The line passes through (0,4), and this gives the y-intercept, which would equal 4.

The equation now would be: y = 1/2x + 4
