Answer:

  (0, 1/5)

Step-by-step explanation:

Since b is 2/5 of the distance from a to c, it is ...

  b = a + 2/5(c -a) = 3/5a +2/5c

  b = (3a +2c)/5 = (3(-8, 3) +2(12, -4))/5 = (-24+24, 9-8)/5 = (0, 1/5)

Point b is (0, 1/5).

Answer:

364.8 ft^2.

Step-by-step explanation:

I  assume you want the area of the figure.

Total area = area of the top triangle + area of the trapezium

= 1/2 * base * height + 1/2 * height * ( sum of the parallel sides)

= 1/2 * 18 * 6 + (14/2)( 18 + 26.4)

=  54 + 310.8

= 364.8 ft^2.

What shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6
Arlecino [84]

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

ax^2+bx+c=0

So, a is the coefficient of x^2, b is the coefficient of x and c is the constant term.

In your case, the coefficient of x^2 is -3, so a=-3

The coefficient of x is -2, so b = -2

The constant term is 6, so c = 6
