What is the equation of the line? Write in standard form. (4,5).
dezoksy [38]

Answer:

\large\boxed{5x+4y=20}

Step-by-step explanation:

The equation of a line in slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the x-intercept = 4 → (4, 0), and y-intercept = 5 → b = 5.

Therefore we have the equation:

y=mx+5

Put the coordinates of x-intercept to the equation:

0=4m+5          <em>subtract 4m from both sides</em>

-4m=5           <em>divide both sides by (-4)</em>

m=-\dfrac{5}{4}

Finally we have the equation of a line if slope-intercept form:

y=-\dfrac{5}{4}x+5

The standard form:

Ax+By=C

Convert:

y=-\dfrac{5}{4}x+5             <em>multiply both sides by 4</em>

4y=-5x+20               <em>add 5x to both sides</em>

5x+4y=20

The perimeter of an equilateral triangle is 51 feet.what is the length of one of its side?explain your work
satela [25.4K]

Hello!

The answer is: 17 ft.

Explanation:

To find this out, just divide the perimeter, and the amount of sides in a triangle, which is 3. This will only work with equilateral triangles because an equilateral triangle has all three sides the same length. Anyway, divide 51 and 3. (51 / 3 = 17) Just to make sure, you can add three 17's together, 17 + 17 + 17 = 51, the perimeter.

I hope this helped! ~Q
