7. For a triangle to be equilateral, all 3 sides must be of equal length. This implies that all corners must be equal. To find out if this is the case we have to find variable x. Never draw conclusions from the drawing.

We know that all corners of the triangle should add up to 180. So:

2x + 2x + (3x-30) = 180 => 7x = 210 => x=30

Also, 2x = 3x-30. All cornders are 60°!

So yes, this triangle is indeed equilateral. If it is equilateral, it is for sure also isosceles (for that, only two sides need to be the same).

k0ka [10]
The total revenue for the event would the total amount earned from the tickets sold. So if x people attended the event, then there would be $(161x). We must keep in mind though the the maximum seating is 76 876. That means that the maximum revenue that can be earned must not exceed $(161)(76 867) = . Hence we have f(x) = 161x where 0 ≤ x ≤ 76867. From this, we can see that the domain is [0, 76867] while range is [0, 12375587]<span>.</span>

Which is the equation of the line that passes through the points (-4, 3) and (2, -6)?
olga55 [171]

Answer:

B) y=-3/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-6-3)/(2-(-4))

m=-9/(2+4)

m=-9/6

simplify

m=-3/2

y-y1=m(x-x1)

y-3=-3/2(x-(-4))

y-3=-3/2(x+4)

y=-3/2x-12/2+3

y=-3/2x-6+3

y=-3/2x-3
