Equation: Y = mx + b
1. Slope
Slope = 3

2. Y-Intercept
Y = mx + b
2 = (3)(-1) + b
2 = -3 + b
2 + 3 = -3 + 3 + b ***-3 on the right side cancels out.
5 = B

So, in conclusion, the equation for this line is: Y = 3x + 5.

vesna_86 [32]
This is an Arithmetic Progression with 1st term 11 and common difference d=6

Number of Rows     Number of seats      Common difference " d" 
-----------------------     -----------------------     -------------------------------------
1st                                  a₁     = 11                                 
2nd                                 a₁+d =17               d =2nd - 1st = 6
3rd                                  a₁ +2d = 23           d =3rd - 2nd = 6
4th                                  a₁ +3d = 29            d= 4th - 3rd = 6
-------------------------------------------------------------------------------
nth ROW                         a(n) = a₁ + (n-1)d
18th ROW                       a₁₈ =   11 + (18-1).6 = 11+(17)(6) = 113 

General equation to predict the number of seat an the nth row:
Number of seats in nth row = a₁ + (n-1).d

Svetradugi [14.3K]

Answer: Total cost to make 12 pennants is $52.5.

Step-by-step explanation:

Since we have given that

There is a rectangle and a triangle.

Length of rectangle = 1 ft

Width of rectangle = 3 ft

So, Area of rectangle is given by

Area=Length\times Breadth \\\\Area=1\times 3\\\\Area=3\ ft^2

Base of triangle = 1 ft

Height of triangle = 1 ft

So, Area of triangle is given by

Area=\frac{1}{2}\times base\times height\\\\Area=\frac{1}{2}\times 1\times 1\\\\Area=\frac{1}{2}\ ft^2

So, Total area of the pennants will be

3+\frac{1}{2}\\\\=\frac{6+1}{2}\\\\=\frac{7}{2}\ ft^2

Number of pennants = 12

Cost per square foot of pennant = $1.25

So, Total cost for 12 pennants is given by

12\times \frac{7}{2}\times 1.25\\\\=\$52.5

Hence, Total cost to make 12 pennants is $52.5.
