Yes
[5.5+(-2.3)] can be rearranged to be 5.5-2.3. It will be 3.2
(-5.5+2.3) can be rearranged to be 2.3-5.5. It will be -3.2
3.2-3.2=0
Answer:
Length = 502 ft
Width = 212 ft
Step-by-step explanation:
Recall the formula for the perimeter of a rectangle of length "L" and width "W":
Perimeter = 2 L + 2 W = 1428 ft
Now, since the length is 78 ft more than twice the width, then we can write this in mathematical form as:
L = 2 W +78
so, 2 W = L -7 8
and now replace "2 W" with it equivalent "L - 78" in the first perimeter equation and solve for "L":
2 L + L - 78 = 1428
3 L = 1428 + 78
3 L = 1506
L = 1506/3
L = 502 ft
Then the width W can be obtained via:
2 W = L - 78
2 w = 502 -78
2 W = 424
w = 212 ft
Answer:
Step-by-step explanation:
We have the equation 
with the initial condition 
. It is not difficult to notice that this is a linear equation, which has the general expression
.
The solution of this equation is expressed by a general formula:
.
In the particular case of our equation, we have
.
Then, we must calculate the integrals
that implies
,
and
Then,
.
In order to obtain the value of the constant we substitute the initial condition
that implies 
Therefore,
.
When using the format of y=mx+b, m is equivalent to the slope and the y intercept is equivalent to b. When you plug the values into the equation, the result is y=-1x+7.
