Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27,
Vera_Pavlovna [14]

Answer:

y=9x

y=\frac{18x}{2}

y=\frac{81x}{9}

Step-by-step explanation:

The given equation is

3y=27x

If we isolate y, we can find the constant

y=\frac{27x}{3}\\ y=9x

So, the constant is k=9.

Another proportions that have the same constant as the given equation are

y=9x

y=\frac{18x}{2}

y=\frac{81x}{9}

<u>Correct </u><u>Inputs </u><u>:-</u>

In ΔABC right angled at A, D and E are points on BC, C such that BD = CD and AD ⊥ BC

\underline{\underline{\large\bf{Solution:-}}}\\

\longrightarrow Let us know about definition of altitude first. The altitude of a triangle is the perpendicular line segment drawn from the vertex to the opposite side of the triangle.

\leadstoMedian is the line segment from a vertex to the midpoint of the opposite side.

<u>Let us Check all options one by one </u>

  • CD is line segment which starts from vertex C but don't falls on opposite side AB thus it is not an altitude.❌

  • BA is line segment which starts from vertex B and falls perpendicularly on opposite sides AC and is thus an altitude.✔️

  • AD is line segment which starts from vertex A and falls perpendicularly on opposite side BC and is thus an altitude.✔️

  • AE is a line segment which starts from vertex A but doesn't falls perpendicularly on opposite side BC and is thus not an altitude.❌

  • AD falls on BC with D as mid point because BD = CD and is thus a median. ✔️

Write the standard form of the equation of the line through the given points.
fenix001 [56]
You first have to find the slope using the slope formula.  That looks like this with our values:  \frac{-2-(-1)}{5-(-3)}=- \frac{1}{8}.  So the slope is -1/8.  Use one of the points to first write the equation in y = mx + b form.  We have an x and a y to use from one of the points and we also have the slope we just found.  Filling in accordingly to solve for b gives us -2=5(- \frac{1}{8})+b  and  -2=- \frac{5}{8}+b.  Adding 5/8 to both sides and getting a common denominator gives us that  b=- \frac{11}{8}.  Writing our slope-intercept form we have y=- \frac{1}{8}x- \frac{11}{8}.  Standard form for a line is Ax + By = C...no fractions allowed.  So let's get rid of that 8 by multiplying each term by 8 to get 8y = -x - 11.  Add x to both sides to get it into the correct form:  x + 8y = -11

Graph a parabola whose vertex is at (3,5)(3,5)left parenthesis, 3, comma, 5, right parenthesis with yyy-intercept at y=1y=1y, eq
Rudik [331]

Using the given information we found that the equation of the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.

<h3>How to get the equation of the parabola?</h3>

For a parabola with vertex (h, k), the equation is:

y = a*(x - h)^2 + k

Here the vertex is (3, 5), so the equation is:

y = a*(x - 3)^2 + 5

And the y-intercept is y = 1, this means that:

1 = a*(0 - 3)^2 + 5

1 = a*9 + 5

1 - 5 = a*9

-4/9 = a

So the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.
