Answer:
y + 9 = - 10(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, - 9) and (x₂, y₂ ) = (- 10, 101)
m = 
= 
= - 10
Using (a, b) = (1, - 9), then
y - (- 9) = - 10(x - 1), that is
y + 9 = - 10(x - 1)
Answer:
194
Step-by-step explanation:
Rectangles :
7 x 10 = 70
6 x 10 = 60
4 x 10 = 40
Triangles
= 12 (two of them = 24)
70 + 60 + 40 + 24 = 194
The product of 9 and a to the power of 2
To answer this question, we will need to get the price of one cake in each package.
For package 1:
The package has 12 cakes and costs $6.80, this means that:
price of one piece = 6.80 / 12 = 0.5666 which is approximately $0.6
For package 2:
The package has 30 cakes and cost $15.16, this means that:
price of one piece = 15.16 / 30 = 0.505 which is approximately $0.5
Comparing the two prices, we will find that the best buy is the second package where the price of one piece is less.
