If you know that b=0, then ab=bc doesn't tell you anything about
'a' or 'c', because no matter what they are, it's always true.
Answer:
f(1) = 5, f(2) = 8, f(3) = 11
Step-by-step explanation:
Common difference refers to how you get from one value in the sequence to the next.
If f(0) = 2, f(1) = 2 + 3 = 5 etc
Using the given information, we can say the following:
Width (W) = x
Length (L) = (2x - 4)
Area of Rectangle = L × W
Using this, we can formulate an equation for rectangle in question:
x(2x - 4) = 30
Expand and move everything to one side:
2x² - 4x - 30 = 0
Simplify by dividing everything on both sides by 2:
x² - 2x - 15 = 0
Factorise:
(x + 5)(x - 3) = 0
Set each factor equal to 0 and solve for x:
x + 5 = 0
x = -5 (a dimension cannot be negative so this is not the solution we want)
x - 3 = 0
x = 3 (this is the solution)
x = W = 3"
L = 2x - 4
L = 2(3) - 4
L = 2"
So, the length the rectangle is 2" and the width is 3"
(4,3)(2,2)
slope = (2 - 3) / (2 - 4) = -1/-2 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur sets of points...(4,3)...x = 4 and y = 3
now we sub and find b, the y int
3 = 1/2(4) + b
3 = 2 + b
3 - 2 = b
1 = b
so ur equation is : y = 1/2x + 1 <==
Answer: y = -9x + 0.5
