9514 1404 393

Answer:

  24 square units

Step-by-step explanation:

The triangle is a right triangle with legs 6 and 8. Its area is ...

  A = 1/2bh = 1/2(6)(8) = 24 . . . . square units

_____

<em>Additional comment</em>

The equation for a line in <em>intercept form</em> is ...

  x/a + y/b = 1

where 'a' and 'b' are the x- and y-intercepts, respectively. If we divide the given equation by 2, we get ...

  x/6 +y/8 = 1

showing us that the x- and y-intercepts are 6 and 8. This is also clear on the graph.

If B is the midpoint of AC and AB = 4x + 14 and BC = x + 20, determine how long AC is.
Serhud [2]

Answer:

44 units

Step-by-step explanation:

Since B is the mid-point of AC

AB=BC

or,4x+14=x+20

or, 4x-x=20-14

or 3x=6

or,x=6/3=2

AC=AB+BC

= 4x+14+x+20

= 4(2) + 14 +2 +20

= 8+14+22

=44 units

Which point gives the vertex of ƒ(x) = –x2 + 4x – 3?
Dmitriy789 [7]

Answer:

The vertex is (2,1)

Step-by-step explanation:

ƒ(x) = –x^2 + 4x – 3

Factor out the negative

   = -(x^2 -4x+3)

 Factor

What 2 numbers multiply to +3 and add to -4

-3*-1 = 3

-3+-1 = -4

f(x) =  -( x-3)(x-1)

Find the zeros

0 = -( x-3)(x-1)

0 = x-3   0 = x-1

x=3            x=1

The x value of the vertex is 1/2 way between the two zeros

(3+1)/2 = 4/2 =2

To find the y value, substitute x=2 in

f(2) =  -( 2-3)(2-1)

       =-(-1)(1) = 1

The vertex is (2,1)
