The linear function is y = .25x + 1
Answer:
t(n)= 0.2 * 2ⁿ
Step-by-step explanation:
Thickness= 0.2 millimeters
paper = 1
n= number of folds
The exponential function will be given by
t(n)= 0.2 * 2ⁿ
so if there's a single fold
t(1)= 0.2 * 2¹
t(1)= 0.4 mm
Now for 2 folds the thickness will be
t(2) = 0.2 *2 ²
t(2)= 0.2 *4
t(2) = 0.8mm
The exponential that represents this scenario is
t(n)= 0.2 * 2ⁿ
And for 3 folds the thickness will be
t(3) = 0.2 *2 ³
t(3)= 0.2 *8
t(3) = 1.6 mm
Answer:
no it isn't it would be 6/9
<h3>The solution is (x, y) = (-2, 3)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 5y = 7 ------ eqn 1
3x -2y = -12 ------- eqn 2
Multiply eqn 1 by 2
8x + 10y = 14 ------ eqn 3
Multiply eqn 2 by 5
15x - 10y = -60 ------- eqn 4
Add eqn 3 and eqn 4
8x + 10y = 14
15x - 10y = -60
( + ) -------------
23x = -46
<h3>x = -2</h3>
Substitute x = -2 in eqn 1
4(-2) + 5y = 7
-8 + 5y = 7
5y = 15
<h3>y = 3</h3>
Thus the solution is (x, y) = (-2, 3)
