It would be equal to 0.45 = 45/100 = 9/20
so, your answer is 9/20
The equation for point-slope is y-yi=m(x-xi).
In your given problems, you would use the given coordinate and plug in the x for xi and the y coordinate for yi. The y and x are left alone ( this is how you solve for y=mx+b).
Ex. #1: (2,2) m=-3
Equation: y-yi = m(x-xi)
y-2 ( y coordinate) = -3(x-2)(the x coordinate).
Simplify y-2 = -3x+6 —> y=-3x+8
1500 + 6000 = 0.9(3 * 12)x
7500 = 32.4x
7500/32.4 = x
231.48 = x......hmmm...not quite...I would go with 232

Answer:
40 cm²
Step-by-step explanation:
The area is given by the formula ...
A = bh
A = (8 cm)(5 cm) = 40 cm²

The length of the slanted side is irrelevant. The height is measured perpendicular to the base.
