Y = ax + b;
0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;
y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
The information we know:
1 week = 134 inches
x = 714
What I did was, I divided 714 by 134 to find the amount of weeks:
So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long

Answer:
21
Step-by-step explanation:
cross multiply
42 x 24 = 48x
1008 = 48x
x = 21
Answer: 8x - 6
Step-by-step explanation:
Perimeter is found by doing 2l + 2w
The length is 3x - 7 and width is x + 4
2(3x - 7) + 2(x + 4) =
6x - 14 + 2x + 8 =
8x - 6
