Answer:
v =7/75
Step-by-step explanation:
5/3v = 125/7
cross multiply
5*7 = 125 *3v
35 = 375v divide by 375
v = 35/375
v =7/75
Answer:
g(f(x)) = x
Step-by-step explanation:
You are given f(x) = -4x - 1 and g(x) =
. Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.
You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).
It will look like: g(-4x - 1) = 

Now evaluate the expression to solve the problem. Start by combining like terms.

You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:

Hello from MrBillDoesMath!
Answer:
Yes!
Discussion:
a + b= 2a => subtract "a" from both sides
a - a + b = 2a - a => as (a-a) = 0 and (2a-a) = a
b = a (*)
Then from (*) above
b-a = b - b => b-b = 0
b -a = 0
Thank you,
MrB
<span>Congruence between two triangles means six items, all three sides and all three angles, are congruent. Thus the statement ABC DEF has a very precise meaning. It succinctly summarizes the six statements (assume lines atop these segments): ABDE, BCEF, ACDF, AD, BE, and CF. It is very important to maintain the vertices in the proper order. Not doing so is a common mistake.</span>
Formula for area of a rectangle is: A = l x w
A: Area
l: length
w: width
length of football field is 100 yards and width is 53.3 yards.
To find the area we need to multiply the length by width.
Area of football field = 100 x 53.3 = 5330 square yards (yards^2)
