A polygon is said to be a heptagon if it has 7 vertices, 7 sides and 7 angles. A heptagon is called a convex heptagon if the lines connecting any two non-adjacent vertices lie completely inside the heptagon

The formula of number of diagonals in any polygon is $d=\frac{n(n-3)}{2}$ , where

d is the number of the diagonals of the polygon
n is the number of sides of the polygon

∵ The heptagon has 7 sides

∴ n = 7

∵ The number of diagonals = $\frac{n(n-3)}{2}$

- Substitute n by 7 in the rule above

∴ The number of diagonals = $\frac{7(7-3)}{2}$

∴ The number of diagonals = $\frac{7(4)}{2}$

∴ The number of diagonals = $\frac{28}{2}$

∴ The number of diagonals = 14

The convex heptagon has 14 distinct diagonals can be drawn

Jodie bought some shirts for $6 each. Marge bought some shirts for $8 each. The girls spent the same amount of money on shirts.

Given f = 95c + 32, the conversion formula for fahrenheit to celsius, solve for

vodomira [7]

The conversion formula is f = (9/5) c + 32 [ The 95c is very confusing!]

(9/5)c = f - 32

Multiply both sides by 5/9:-

c = (5/9) ( f - 32)

That's option a).

1. ( -1,2) is the same as (x=-1, y=2)
Substitute in your equation
y=3x-2
2=3•(-1)-2
2=-5 this is NOT true so (-1,2) is not a solution for the equation y=3x-2

2. (0,-2)
9x-6=3y
9(0)-6=3•(-2)
-6=-6 this is true so ( 0, -2) is a solution for the given equation
