Answer:

The point (2, -1 ) is not on the graph of the line.

Step-by-step explanation:

3x–4y–12=0

3*2 - 4*(-1) - 12= 0

6 + 4 - 12 =0

10 - 12 = 0

- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.

Goryan [66]

Answer:

See below.

Step-by-step explanation:

Recall that the biggest angle will always be opposite from the biggest side.

IT is opposite from Angle S, which we can figure out to be 180-108-25=47.

SI is opposite from Angle T, which is 41.

ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.

The smallest side is SI, then IT, then ST.

The correct order is: SI, IT, and ST.

The center of a circle lies on the line y=6x+2 and is tangent to the X axis at (-2,0) what is the equation of the circle in stan
Murrr4er [49]

Answer:

(x+2)^2 + (y+10)^2 = 100

Step-by-step explanation:

y = 6x + 2

Z(-2,0)

x = -2

y = 6 x (-2) + 2

y = -12 + 2

y = -10

M(-2, -10)

r = 0 - (-10) = 10

(x + 2)^2 + (y + 10)^2 = 100

First Hour :
--------------------------------
150 people bought the tickets

--------------------------------
Second Hour :
--------------------------------
20 % of 150 = 0.2 x 150 = 30
150 + 30 = 180

180 people bought the tickets

--------------------------------
Third Hour :
--------------------------------
10% of 180 = 0.1 x 180 = 18
180 - 18 = 162

162 people bought the tickets

Total customers :
--------------------------------
150 + 180 + 162 = 492
