The equation of a line is y = mx+b where m is the slope and b is the y-intercept.

The slope is 5/6 and y-intercept is -3


The equation would be y = 5/6m - 3

Hi BeeBeeBumble,

Solution:

To find the equation you look at the first sentence of your question.

You see that its 5/6 and -3

You know that you can take away the negative from negative 3 then just subtract.

Final Answer:

B. 5/6 - 3

Which is the standard form of the equation of the parabola that has a vertex of (3, 1) and a directric of x = -2?
vagabundo [1.1K]
Check the picture below.  So,the parabola looks like so, notice the distance "p". since the parabola is opening to the right, then "p" is positive, thus is 5.

\bf \textit{parabola vertex form with focus point distance}\\\\
\begin{array}{llll}
\boxed{(y-{{ k}})^2=4{{ p}}(x-{{ h}})} \\\\
(x-{{ h}})^2=4{{ p}}(y-{{ k}}) \\
\end{array}
\qquad 
\begin{array}{llll}
vertex\ ({{ h}},{{ k}})\\\\
{{ p}}=\textit{distance from vertex to }\\
\qquad \textit{ focus or directrix}
\end{array}\\\\

\bf -------------------------------\\\\
\begin{cases}
h=3\\
k=1\\
p=5
\end{cases}\implies (y-1)^2=4(5)(x-3)\implies (y-1)^2=20(x-3)
\\\\\\
\cfrac{1}{20}(y-1)^2=x-3\implies \boxed{\cfrac{1}{20}(y-1)^2+3=x}

Hello if someone could explain this question that would be great. Thanks.
guajiro [1.7K]

Answer:

Ok time to get math on

So this would be D

A non-filled in dot means < or > (depending where arrow is pointing)

A filled in dot means ≤ or ≥ (depending where arrow is pointing)

if an arrow points right, then it would be greater than, if arrow points left.. Then its less than

So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D

A is greater than which is not the answer

B is only equal to which is way off

C is less than but it is equal which is wrong

D is the only right answer

Hope this helps! :)

AURORKA [14]
1/2 (-4x + 12)= 26

-4x + 12= 52

-4x = 52 - 12

-4x = 40

x= 40/-4

x= -10

The answer is B. x = -10
