Answer:
y-3=-3(x+2)
Step-by-step explanation:
Point-slope form is y-y1=m(x-x1).
So if the coordinates given are (-2,3) you substitute the y1 and x1 with those variables, along with determining the slope which is -3/1 because the line goes up towards the left rathar than the right side making it negative.
And there's your equation! Hope that helped.
Answer:
3, 6, 9
Step-by-step explanation:
To find the first 3 terms , substitute n = 1, 2, 3 into the n th term rule.
a₁ = 3(1) = 3
a₂ = 3(2) = 6
a₃ = 3(3) = 9
The area of a triangle is (base*height)/2
Therefore: 12*10=120/2=60. Since there are three triangles then you multiply 60 by three. 60*3=180
Since the triangle in the middle is equilateral the height is 10. (10*10)/2=50
180+50=230
The answer is 230 inches²
4y:5y would be the simplest form
