A. -6/7

Because:
(2,6) (8,-1)

(x1,y1) (x2,y2)

x1 = 2. Y1=6. X2=8. Y2= -1.

Equation for slope is m = y2-y1
x2-x1
-1-6 = -7
8-2=6

Determine the range of the following graph:
Vlada [557]

Answer as an inequality:    \boldsymbol{2 \le y \le 7}

Answer in interval notation: [2, 7]

==========================================================

Explanation:

The range is the set of all possible y outputs of a function.

The lowest point occurs when y = 2

The highest point occurs when y = 7

The range is the set of every y value between 2 and 7, including the endpoints.

The range as an inequality is 2 \le y \le 7

It is equivalent to [2, 7] in interval notation. The square brackets include each endpoint.

olchik [2.2K]

Answer:

  $18500 at 6% and $28500 at 8%

Step-by-step explanation:

Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:

  x·6% +(x+10000)·8% = 3390

  0.14x + 800 = 3390 . . . . . . . . collect terms

  0.14x = 2590 . . . . . . . . . . . . . .subtract 800

  2590/0.14 = x = 18500 . . . . . divide by the coefficient of x

Sue has invested $18500 at 6% and $28500 at 8%.

Answer:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
