\\ \rm\longmapsto y-6=4(x+5)

  • Convert to y=mx+c

\\ \rm\longmapsto y-6=4x+20

\\ \rm\longmapsto y=4x+20+6

\\ \rm\longmapsto y=4x+26

  • c is y intercept
  • m is x intercept

y intercept=26

What is the equation for this line
pogonyaev

The equation of the line is y=\frac{-1}{5} x-\frac{21}{5}.

Solution:

The points on the line are (–6, –3) and (4, –5).

 x_{1}=-6, y_{1}=-3, x_{2}=4, y_{2}=-5

Slope of the line:

 $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

 $m=\frac{-5-(-3)}{4-(-6)}

 $m=\frac{-5+3}{4+6}

$m=\frac{-2}{10}

$m=\frac{-1}{5}

Point-slope formula:

 y-y_{1}=m\left(x-x_{1}\right)

 $y-(-3)=\frac{-1}{5}(x-(-6))

 $y+3=\frac{-1}{5}(x+6)

 $y+3=\frac{-1}{5} x-\frac{6}{5}

Subtract 3 from both sides of the equation.

$y=\frac{-1}{5} x-\frac{21}{5}

The equation of the line is  y=\frac{-1}{5} x-\frac{21}{5}.

The level of the tide in a harbor changed from 9 1/4 ft to 4 1/2 ft above sea level over a period of 3 1/4 hr
kumpel [21]

Answer:

The answer is "\bold{- \frac{19}{13} \ / hour}"

Step-by-step explanation:

Please find the complete question in the attached file.

Calculating the difference of 9 \frac{1}{4}\ and \ 4 \frac{1}{2}  dividing the value by 3 \frac{1}{4}

\to 4 \frac{1}{2} - 9 \frac{1}{4}\\\\ \to  \frac{9}{2} - \frac{37}{4}\\\\  \to  \frac{18-37}{4} \\\\ \to -\frac{19}{4}\\\\\to -\frac{19}{4} \div \frac{13}{4}= -\frac{19}{4} \times \frac{4}{13} = -\frac{19}{13}\\

Please solve with working much appreciated
mojhsa [17]

Answer:

x°= 55°

Step-by-step explanation:

First, find the degrees of the larger triangle.

Since every triangle equals 180° degrees, make an equation.

60°+90°+a°= 180°

Now, add the degrees together.

120°+a°= 180°

Then subtract from both sides.

120°+a°= 180°

-120 °      -120°

a°= 60°

Now that you know the sum of all the angles, subtract 25° from 60°(which is the measure of a).

60°-25°= 35°

Now that we have the measurement of the angle from the smaller triangle inside the larger one, make an equation.

35°+90°+x°= 180°

Then, add the degrees.

125°+x°= 180°

Subtract from both sides of the equation to get the answer for the variable.

125°+x°= 180°

-125°       -125°

x°= 55°
