A seamstress is making a decorative pillow and wants to sew lace around the trim. The pillow is in the shape of a triangle with

vertices (7, 7) (10, 3) (7, 3). How many inches of lace will she need if each unit on the grid is one inch?

Use the distance formula in order to find the length of each side of the triangle. 

<span>>(7, 7) & (10, 3)
</span>√[(7-10)² + (7-3)²] = 5
<span>
></span><span>(10, 3) & (7, 3)
</span>√[(10-7)² + (3-3)²] = 3

>(7, 7) & (7, 3)
√[(7-7)² + (7-3)²] = 4

Adding all lengths (or solving for perimeter), we have: 5 + 3 + 4 = 12 

The seamstress will need 12 inches of lace.

A line passes through the point (0,2) and has a slope of -1/2 what is the equation of the line
emmasim [6.3K]

Answer:

y = -1/2x + 2

Step-by-step explanation:

A line in slope-intercept form in y = mx + b

"m" is the slope

"b" is the y-intercept

x and y represent points on the graph

To write an equation, you need "m" and "b".

We already know m = -1/2

The point (0, 2) is the y-intercept. The y-intercept occurs when x = 0.

Points are in the form (x , y), so x = 0 and y = 2.

Therefore b = 2.

Substitute m = -1/2 and b = 2 into the equation:

y = mx + b

y = -1/2x + 2

Answer:

Area: 135 ft^2

Perimeter: 50 ft

Step-by-step explanation:

area:

take the rectanle so length 12 x 9 = 108 so that is the length of the rectangle and now we need to find that of the triangle left over

subract 18 - 12 = 6 so that is the base of the trianle and we know the side length is 9 so plus it in A = (9)(6)/2

A = 54/2

A = 27

add 27 + 108 to get the total area

135

perimeter:

18 + 9 + 11 + 12 = 50
