This is a parabola which opens upwards 

y - (-3) = sqrt ((y+1)^2 + (x + 5)^2

(y + 3)^2 = y^2 + 2y + 1 + (x + 5)^2
y^2 + 6y + 9 = y^2 + 2y + 1 + (x + 5)^2

(x + 5)^2 =  4y + 8

(x + 5)^2 = 4(y + 2)

Which graph best represents -5y = -6x + 15
frutty [35]

Answer: Option c.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

-5y = -6x + 15

Solve for "y" in order to write in Slope-Intercept form:

y = \frac{-6}{-5}x + \frac{15}{-5}\\\\y = \frac{6}{5}x -3

Now you can identify that that the slope and the y-intercept are:

m=\frac{6}{5}\\\\b=-3

A posive slope means that the the line moves upward from left to right.

With this information, you can conclude that the the graph that  best represents the given equation is the graph shown in the Option c.

Is 15,36,39 a right triangle
NeTakaya

Answer:

Yes, is a right triangle

Step-by-step explanation:

To know if you can build a right triangle with those sides we have to make the following equality

h² = l1² + l2²

The hypotenuse is always the longest side so it should be 39

we check the equality of the equation

39² = 15² + 36²

1521 = 225 + 1296

1521 = 1521

Equality was fulfilled so it is a right triangle
