Exponential
Step-by-step explanation:
So let’s start off by looking at how much x is growing by each time
X is growing by 8 each time
Next look at how much y is growing by
-6 to -24 is a difference of 18
-24 to -96 is a difference of 72
And lastly -96 to -384 is a difference of 288
So we can now say that it is not linear because a linear equation grows by a constant number (like adding)
To determine if it is exponential see if it is growing by a constant multiplier
24 divided by 6 is 4
96 divided by 24 is 4
384 divided by 96 is 4
It is exponentially growing by 4
Answer:
3
Step-by-step explanation:
f(3) = 2*3 -3
= 6-3=3
f(f(3)) = f(3)
so again,
f(3) = 2*3 -3
= 6-3= 3
The slope
and a point
that the line goes through, give us a equation for the line:
<h2>Length = 11</h2><h2>Width = 6</h2>
The area of a rectangle is 66 ft^2:
L * W = 66
Length of the rectangle is 7 feet less than three times the width:
L = 3W-7
Substitute L in terms of W:
(3W-7) * W = 66
Factorise the equation:
3W^2 -7W = 66
3W^2 - 7W - 66 = 0
Factors of 66 =
1 66, 2 33, 3 22, 6 11
(3W + 11) (W - 6) = 0
Solve for W:
3W + 11 = 0
3W = 11
W = 3/11
W - 6 = 0
W = 0 + 6
W = 6
Using the original equation, find L:
L = 3W-7
L = 3(6)-7
L = 18-7
L = 11
L * W = 66
11 * 6 = 66
