Answer:
y-intercept is zero
Step-by-step explanation:
The general equation of the line passing through the points is
y = mx + b
where m is the slope and b is the y-intercept
We can pick any two points to get the slope of the line;
m = (55.25-8.5)/(13-2) = 46.75/11 = 4.25
So partially , the equation will be;
y = 4.25x + b
To get b , substitute any point and use its x and y values
We have (2,8.5)
8.5 = 4.25(2) + b
b = 8.5-8.5
b = 0
Set up variables:
l = length
w = width
p = perimeter
A = area
Relations:
A = lw
32 = 2l + 2w (perimeter)
l = 3w
Find the missing info:
32 = 2(3w) + 2w (solve for w)
32 = 6w + 2w = 8w
w = 32/8 = 4
If width equals to 4, then length would be 4 * 3, 12.
Area = 12 * 4 = 48
Answer:
2 1/2 or 2.5
Step-by-step explanation:
For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
Then, we can rewrite the expression as:
