Henry built one garden that is 3 feet wide and 3 feet long. He also built a garden that is 3 feet wide and 6 feet long, and a ga
SOVA2 [1]

Let's calculate the areas of all three gardens

First garden

one garden that is 3 feet wide and 3 feet long

Area = length* width = 3 feet * 3 feet = 9 square feet


Second garden

3 feet wide and 6 feet long

Area = 3 feet * 6 feet = 18 square feet


Third garden

3 feet wide and 9 feet long

Area = 3 feet * 9 feet = 27 square feet


It means as we can see as the length increases by 2 times , the area also increases by 2 times every time.

(7.06) what function is represented below
wel

I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)


The pattern is each increment of 1/2 in x divides by two.


f(x) = (\frac k 2)^{2x} = \frac{k}{4^x}


Any of the points give k=16


f(x) = 16( 4 ^{-x} )  = 4^{2-x}


Check: x=1/2 4^(3/2)=2^2=8 good


x=1 4^(2-1)=4 good


x=2 4^(2-2)=1 good


x=3 4^(2-3)=1/4 good

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8. Simplify R - S + T
galben [10]

Q=7m+3n\\R=11-2m\\S=n+5\\T=-m-3n+8\\\\R-S+T=(11-2m)-(n+5)+(-m-3n+8)\\\\=11-2m-n-5-m-3n+8\\\\=(-2m-m)+(-n-3n)+(11-5+8)\\\\=\boxed{-3m-4n+14}

Write an augmented matrix for the following system of equations
chubhunter [2.5K]
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
