A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2,

Oksanka [162]

Answer:

A. one B. (3, 4)

Step-by-step explanation:

1. A good graph can answer both parts (see attached image).

2. Write equations for the two lines and find a simultaneous solution.

Line A: Slope from (2, 6) to (5, 0) is $m=\frac{6-0}{2-5}=\frac{6}{-3}=-2$

Using point-slope form $y-y_1=m(x-x_1)$

$y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10$

Line B: Slopt from (6, 6) to (0, 2) is $m=\frac{6-2}{6-0}=\frac{2}{3}$

Using point-slope form, the equation for Line B is

$y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2$

To find the simultaneous solution, set the y's equal.

$-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3$

Find y using either equation to get y = 4.

The area of a field shaped like a right triangle is 750yd^2.One leg of the field is fenced with wood costing $5/yd. the remainde

Elenna [48]

Assume that
a and b = the two legs of the right triangle.
c = the hypotenuse.

The area of the right triangle is 750 yd², therefore
(1/2)*a*b = 750
ab = 1500 (1)

The perimeter is 150yd, therefore
a + b + c = 150 (2)

Let the side fenced with wood be a, at $5/yd. Sides b and c are fenced with steel at $10/y. The total cost is $1200, therefore
5a + 10b + 10c = 1200
or
a + 2b + 2c = 240 (3)

From (2), obtain
c = 150 - a - b (4)

Substitute (4) into (3)
a + 2b + 2(150 - a - b) = 240
-a + 300 = 240
a = 60

From (1), obtain
60b = 1500
b = 25

From (4), obtain
c = 150 - 60 - 25 = 65

Answer:
A. The length of the leg fenced with wood is 60 yd.
B. The length of the leg fenced with steel is 25 yd.
