Let the unknown number be x.

Sum means addition, so sum of an unknown number and 0.5 = x + 0.5.

Hence, the algebraic expression is x + 0.5

The word "sum" implies that this equation involves the addition of two or more numbers. Using 'x' in place of "a number" and 'y' as "the sum" we get this:

y=x+.5

Plz help, <br> Graph f(x)=|x−6|−4
sattari [20]

MrBillDoesMath!


Answer: I don't know how to draw graphs  on this website but here's the "picture".  Imagine the function y = absolute value(x). It looks like the English letter "V". The bottom of our V (i.e f(x) touches the x-axis when x = 6, so the "V" graph has been translated 6 units to the right of the origin. But  when x = 6 the value of f(x) is 0-4 = -4 so the tip of the V is located 4 units below the x axis. Summary:  g(x) looks like the absolute value function but  is translated 6 units to the right of the origin and 4 units down

s344n2d4d5 [400]
A square garden plot has an area of 75 ft2.
a. Find the length of each side in simplest radical form.
First, a square area (A) = length (l)^2
A(ft2) = l^2 --> so l(ft) = square root (sr) of A
l = srA = sr75
Next, factor out 75 into number with even roots: 25•3 = 75
So l = sr25•sr3 --> l = 5•sr3 ft
5•sr3 is in the simplest radical form

b. Calculate the length of each side to the nearest tenth of a foot.
l = sr3 = 1.732 --> so 5•1.732 = 8.66ft
Tenth is one place to the right of the decimal, so l = 8.7 ft
