The straight line L has equation 4x + 3y = 72 The point A has coordinates (0, -1)
The straight line M is perpendicular to L and passes through A.
Line L crosses the y-axis at the point B.
Lines L and M intersect at the point C.
Work out the area of triangle ABC.
You must show all your working.

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
