USPshnik [31]2 years ago
8 0

Answer:

Step-by-step explanation:

Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula} 2. Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2.

Area is found by taking the length time width or A=lw

240=L x 15    divide both sides by 15

Length = 16 meters

Can someone help me with this question?
charle [14.2K]
Finding the sol'n to f(x) - g(x) = 0 is the same as finding the solution of f(x)=g(x).  You could do this analytically by setting the actual function f(x) = g(x) and solving for x (and then for y), or you could estimate the solution from the given graph.  The two lines intersect at approx. x=-3.75, y=2.5.

Write the linear eqaution in slope form for x and y. 1/3x+y=-2
Anit [1.1K]

Answer:

y = -1/3x -2

Step-by-step explanation:

Slope intercept form of a line is

y= mx+b

We need to solve for y

1/3x +y = -2

Subtract 1/3x from each side

1/3x -1/3x +y =-1/3x -2

y = -1/3x -2
